Captivate Cant Connect with USB

I've looked everywhere and cant seem to find an answer, so i figured i'd start a new thread.
My captivate used to connect to my computer just fine, but there was another computer it would just NOT connect too! Well, after a few months, it stopped connecting to my home computer as well.
I have USB debugging on, the phone is rooted and everything. When I plug it in and mount the USB drives, i get drives J and K on my computer, one for the internal storage, and one for the SD card i have in the phone.
When double clicking any of those drives, it just sits there and reads forever without ever doing anything. I can use the SDK to run "adb devices" and it see's the phone, Odin One Click finds the phone but freezes on reading file line, or just fails all together.
Any ideas?

Try reinstalling the samsung usb drivers and restart your computer, that'd be my first step.

You have to be on the touch wiz home screen if you're trying to connect to Kies, otherwise turn on USB debugging and you should be good to go

SeenNotScene: I've uninstalled, rebooted, re-installed several times. I've been having this problem for a couple months now and i've tried everything i can think of. It doesnt work
bkhams: I dont even know what Kies is? I always have USB debugging turned on, and once connected i bring down the drop down menu and mount the USB so i can access my phones files as if they were another drive.

I had the same problem, and Samsung peeps told me I had to use the USB cable that came with the phone, low and behold they were right. Connected right away with the USB that came with the phone, could that be your problem?

I had the same problem in the past and it was actually a hardware problem with the Captivate and not anything with the computer. I ended up taking the phone in and they exchanged it for me.
I do not know if yours could be having the same problem, but that was my experience. Frustrating, to say the least.

Hmm... Could be the hardware i guess.. I know its not the cable though because i've only ever used the cable that came with it.

Have you tried connecting to the USB port directly off the motherboard? My connections were "sketchy" at best when using the ports of the top of the computer case. Once I connected directly off the MOBO, zero problems since.

Sloved!

Thank you for suggestions! My front USB connector is probably connected to some internal HUB, not going straight to the motherboard and wont work. Connecting directly to MB USB solve the problem. I am a little bit surprised... but whatever - M$ bull*hits. I spend couple of hours yesterday to find out whats going on. Thank you again!

Phone not being seen by any PC

So this issue started a few days ago. Any time I plugged my phone in it would constantly connect and disconnect from the pc. I've tried multiple usb cables, ports, and the 3 PCs I have with the same result on each. Now when I plug it in, it is no longer being recognized by the PC, Odin, ADB, etc... It will charge but that is it.
I have a warranty replacement coming to me however I need to be able to get this one back to stock... Any suggestions?
Before anyone asks, NO it has never been wet, dropped, damaged in any way, set on fire, caught in a land slide, earthquake, what have you.. The phone itself functions perfectly fine. All drivers are up to date, none of my PCs configurations have changed. I have one I use specifically for app development and not even that one will see the phone.

I had the same problem. I used a different cable and it all worked better....now with that said it happened again so I flashed my phone back to stock and all was well.
Then went to flashing ROMS.

Really check out the micro usb cable. A bad cable will just about always allow a device to charge, but data transfer is another story. If you really have tried a few micro USB cables, then it the problem relies elsewhere. Try restarting both phone and PC, and if neither works, sounds like you have a busted port on the Skyrocket.

Thank you both for your responses. I am a PC technician so I followed my usual troubleshooting steps to figure this out. I narrowed it down to either all of my cables are bad (not a chance) or the phone is just f**ked (likely). Ah well ill have to try to use another way to force the stock firmware and recovery on here. Lol
HTC = Hate The Consumer

I use my old Nokia OEM USB cable. Connects with the right number of pins on the USB connection end. I'd check your USB cables for # of pins . Skyrocket uses 5 I believe. Also that there is sufficient power to your USB ports. Aka avoid front USB ports which could only be 4 pin....

When you plug the usb cable in, do you see the usb icon at the top left of your screen? I have to pull that window down to tell it to connect to pc, then confirm it again before mine connects. Mine doesn't auto connect on its own.
I see you've been a member for a few years so if its not connecting, that really sucks man. Hope you get it figured out.

Not running the AOKP ROM are you? The R3 build had an issue with this, and all AOKP will disable USB to PC if you enable 'fast charge' under ROM Control...
Good luck :S

According to what I've been reading you can try using the *#7284# code and setting the USB portion from PDA to MODEM and then back to PDA and it would kickstart the connection. No dice for me though. Ive been through 7 different USB cables already.. I am not about to go and buy one just to keep playing with it my other phones connect just fine using the same cables. No, I am running the latest Sky ICS

[Q] MacBook (Air and Pro) kills USB File Transfer on my Note Pro 12.2

QUESTION: is there anyone else using a Note 12.2 with an rMBP or MacBook Air, (or any 2012-or newer model Apple MacBook) and the USB connection is fine?
I have a strange issue with my 12.2- I'm trying to get some insight if it's just mine, or can anyone else confirm this one way or another?
When I attach via USB to my 12.2 ONLY on an Apple MacBook (I can replicate it either with my 15" rMBP running Mavericks or a 13" Air running Mountain Lion) the MacBooks completely disable USB file transfer on the device- as in for good, including with any other USB connection on any other computer- until I do a factory reset.
File Transfer works perfectly on all of my PC's running Windows, and on a Hackintosh running Mavericks and my genuine MacPro running Mountain Lion.
It's only the MacBooks that kill the USB connection every time. After it happens, no other device will connect via USB.
It's not a driver issue or anything else- my MacBooks connect perfectly to my Galaxy S3, Note 2 and Note 3 using Android File Transfer. (And other non-Samsung Android devices I own). But the 12.2's connection dies every time, until a factory reset.
I'm thinking this is probably just an issue with my tablet, but would be nice to have some insight before I return it for a replacement. Also I want to make sure I don't just get the same problem happening again, if it's somehow a Apple/MacBook problem not the Note Pro.
Anyone have any ideas why just the MacBook USB ports (and two different OS's) would kill the Galaxy Note Pro? Like maybe they use a different type of USB 3.0 connection or something?

Update: I was exploring the limitations of this issue- it only happens with the original dual Samsung USB 3.0 cable and the MacBooks. A standard microUSB cable and it connects fine and doesn't kill the USB connection.
Again, same Samsung USB 3.0 cable and any other device, no problem. Weird problem.

I also could not use the stock USB 3.0 cable on my rMBP.
I'm guessing it's a USB 3.0 driver issue since even through a VMW Fusion virtual machine I could not get a good connection.
Thanks for the advice on the use of a USB 2.0 cable. It's not as fast obviously but works in a pinch.

This has to be a hardware issue with the Note Pro.
Do you get the same problem? That connecting to your Macbook completely disables USB connections until you do a factory reset? (I'd love to know if there's a better way to fix the USB connectivity other than a factory reset. Nothing in the developer options does it that I know of.)
For now I think I'm still going to exchange for another and see if it's just a glitch with mine that the USB connection is completely killed. If it's true of all Note Pros then it's something Samsung needs to fix.

Not sure what you mean by completely disabling USB connections.
Host mode for external devices? I haven't done that with the tab yet since I don't have an adapter for it.
Or are you talking about only having one shot at connecting the tablet to my rMBP? I'd say no, I can plug and unplug repeatedly to my heart's content using a standard microUSB cable and copy files to/from the device without rebooting let alone factory resetting it.

Ah so clearly this is just my tablet.
Yes, I mean I get one shot to plug into either Macbook (using the Samsung USB 3 cable) and thereafter no USB transfer connection of any sort is possible. The tablet simply doesn't show up on anything. Not even with the standard micro USB cable, and not with any other computer. I have to do a reset to get USB transfer back. If I use the Samsung cable (or the same cable from my Note 3 so it's not the cable itself) with any other computer I own other than the MacBooks, everything is fine. Standard micro USB with anything including MacBooks is fine.
If I'm understanding you right, your tablet won't connect via the Samsung cable to your Macbook but at least it doesn't completely kill the USB transfer just by connecting it.
Any rate I'm taking it back in the morning, and bringing my rMBP to check how the replacement works.

Yep, just the stock cable that came with it doesnt work with my rMBP. At no time have I needed to do a factory reset.
I'm not on Mavericks yet, if that makes any difference or not I don't know.
Good idea to bring the computer in.
Good luck!

The Note Pro 12.2 doesn't connect well with my 15" Retina MacBook Pro either via USB 3.0 cable. The tablet says "connected via USB 3.0" but Android File Transfer (what a piece of junk) doesn't see it. I haven't had to factory reset (which means wipe out) the tablet though. At worst, a reboot gets the tablet working with a USB 2.0 cable. With both 3.0 and 2.0 cable, the tablet shows the "x" through the battery indicating the Mac isn't outputting enough juice to charge, even over USB 3.0. Using a USB hub in general works better than direct connection to the Mac.

Thanks pdagal. Does seem to be an issue with Macs and USB 3.0. An older MacPro with USB 2.0 works fine.
Took mine in and exchanged it this morning at Best Buy. The complete disabling of USB transfer was a unique bug. New Note Pro behaves like you describe- doesn't connect to MacBook via original USB 3 cable, but at least a reboot restores USB transfer function afterwards without a factory reset.
I hope a firmware upgrade will fix this entirely.

I cant comment on the Note pro 12.2 but my note 3 i tend to use OTG cable and a thumb drive to push large files or use drop box. I could never really get android file transfer to even work consistently with my Nexus 10 running Mountain lion or mavericks on different macs.

Do you have Samsung Kies installed? If so it kills AFT until it's completely removed using the uninstaller.
Otherwise I'm surprised people have issues with AFT. It's always worked flawlessly for me on every Mac and Hackintosh I use. Even this issue wasn't an AFT problem at all.

no never did have kies. I have owned Macs and Androids since the G1 and Nexus One and have never much had luck with AFT. I could get it to work every now and then but once i figured out a thumb drive and a OTG usb cable its been just easier to throw files on a thumb drive. But I dont move alot of files around unless its setting up a new phone. Now with my Nexus 10 I use the thumb drive to keep abunch of movies on it so i dont have to worry about space and i have stuff to watch while traveling. Speaking of Hackintosh AFT worked flawlessly on my wifes old dell netbook that I did the hackintosh on.

USB 3.0 Problem

Hi!
Got my Note yesterday, now I got a problem, again. I can't get it work on USB 3.0 no matter what I do (I'm sure about this but I ask this anyway: am I right that SM-P905 have USB 3.0?)
Okay, to the problem:
When connected to USB 3.0 I don't have option to choose USB 3, I only got MTP and PTP
- I updated Kies 3
- I reinstalled drivers (from Kies)
- I have 2 USB 3.0 ports on my PC so not so many to test but:
USB 3.0 works on my Note 3 (SM-N9005) on both USB-ports, It also works well with my Note Pro USB-cable
Note Pro doesn't work (don't give even option to choose USB 3 mode) on any of these two ports. I also tried both ports using my Note 3 USB-cable, but still no luck
So any ideas?
ps. I got ASUS motherboard and I found out someones having similar problems with their Android devices. Reason was ASUS Ai Charger -utility, but I don't have that one never ever istalled on my PC. Oooh, and one more thing, I'm using Win 7 Home Premium (x64)
---------------------------------------------------------------------
Updating BIOS and reinstalling Windows did the trick, now it works like it should

What exactly makes you say it doesn't work? Are you completely unable to transfer data to/from the tablet to a PC, are you not seeing a difference between transfer speeds using a USB 2.0 cable vs a 3.0 cable, OR is the appearance of everything working there but you are wanting the USB 3.0 nag screen to pop up to give you an indication that you're indeed using USB 3.0 ?

When I connect Note to PC USB 3.0 port, pull down notification bar and click USB notification, I get ONLY option to use MTP or PTP. USB 3.0 is not listed there as option. I also transferred about <10Gb size file to Note and it took about 50min, which really is loooooong time..

Okay, here is screenshot about what I meant. Can you please say how it's in your tablet.

Same - Mine connects MTP and I can see it and transfer files but on my tablet I get a Icon in the top tray that says connected to USB 3.0

Same here, when I'm getting a USB 3.0 connection to my PC I'll get the 3.0 indication in the notification screen.
I can't get 3.0 to work with my rMBP but it works with my Windows 7 based workstation and I can definitely see an increase in file transfer speed to the tablet when the USB 3.0 cable is used in a USB 3.0 port. Just did a test from a hard drive on my PC to the tablet, 2.1GB file transferred to internal memory on the Note Pro in 1:18 using a USB 2.0 cable and 0:48 using the stock USB 3.0 cable so I'm getting about 45mb/s with 3.0 and 27mb/s with 2.0.

Okay thanks. Tomorrow I'll check again if notification bar shows USB 3 or not, can't remember right now (still got thought that not). I'll get back here and tell if it's working or not.
EDIT: Yup, no USB 3.0 connection, in notifiction area there is that standard USB icon and it's not saying 3.0
EDIT2: Is there some way to find out if Note charges using USB 3.0? Shouldn't the 3.0 be a lot faster on recharging than 2.0, but how I can know which one it uses?
Sent from my SM-N9005 using XDA Premium HD app

Okay, back to subject..
Does USB 3.0 affect anyway to charging speed? Like if I use stock wall charger with 2.0 or 3.0 cable?
What's your charging speed? I did test and from 50% to 55% it took 15 minutes and from 50% to 65% 45 minutes (which makes average 5%/15min)
To charge I used stock wall charger and stock USB 3.0 cable. I didn't use my NP while charging and mobile data / wifi was OFF
Can you please check how fast is your Note Pro to charge? I still can't make my note to work on 3.0 mode when connected to my PC and I'm trying to find is the problem on my PC or Note before sending this to repair

How about trying Gsam Battery Monitor and observing the charging characteristics that way. It will give you charging current.

With wall charher charging current is 1900mAh, which is normal I think.
Now, if I plug my NP to my computers USB 3.0 port, I get BSOD --> PC reboots and I plug again --> now it works, but still not on USB 3.0 mode. So it could be with drivers or something, tried again install device drivers with Kies 3 but no luck. What could I do? I don't have skills to remove all the drivers and start from clean table (any other way than formatting my pc and that's not gonna happer for a while )
Any ideas?

Okay, just tried with laptop (Win 8.1) and my NP is ok, it connected using USB 3.0.
Now what, if my external HDD and Note 3 works on my own PC via 3.0, what I can do to make my Note Pro work also??
Problem have to be with drivers or something..

Mine doesn't show the "Use USB3.0" option that my Note 3 shows, but it clearly says "Connected as a media device via USB3.0" in the notification bar. (See attached screnshot)
Also, it just copied 1.03GB in 16 seconds from my laptop to my NotePro.
Clearly they removed the USB 3.0 setting from the menu, and it is now done automatically.

I'd start with USBDEVIEW. Google it. Run that with no android devices connected to the PC. Uninstall all drivers related to any android device and reboot the computer. Then try again.
If that doesn't work, consider repeating that, rebooting and then updating the chipset drivers for your motherboard.
After that, I'm out of ideas.
Us Mac users have the same issue; the tablet is simply not recognized as a USB 3.0 device on my rMBP which is running Mavericks. It doesn't matter if I'm running windows as a virtual machine in VMWare Fusion or not so I'm thinking its at the driver level of Mavericks.

I updated them twice, just to be sure. I got 2x USB 3.0 ports on my PC.
My external HD and Note 3 works well with both of them. And Note 3 also works with NP 12.2 cable.
Just my NP wont work no matter which port or cable I use.
On my friends laptop NP 12.2 with the cable that came in the box works well, immediately connects as 3.0 device.
I think I'll quit with this. Don't have the knowledge find out where the problem is.. I thought maby BIOS update might help, but since everything else works fine, I wont do that because the risk of totally f*** up my computer.
But if anyone here got any other/more ideas, I'm listening

You said you had an ASUS motherboard, right? I'd go ahead and update the BIOS, it's pretty fool proof with the newer ones (which you have USB3.0, so it's a safe assumption that it's new enough.)
I also have an Asus motherboard, funny thing is, my Note Pro does show the USB3.0 indicator in the notification bar, but I'm copying files over right now via Linux and it's copying at 9.9MB/s. That's pretty horrible. Added to that, my Note Pro won't charge from the USB port on my computer, but it will from the wall charger. It has a big red X over the battery when plugged into the PC. So I'm not sure if that's somehow related.
Another thought about both of our problems, is that maybe the cable is a little loose or something is in the port-hole. I know mine was a bit flakey for a bit there (as in I would plug it in, create a folder... then tried to rename it and it said it couldn't access the device... I had to try it three times after unplugging and plugging it back in.)
It doesn't make sense though that it's a BIOS and/or driver issue if you also have a Note 3 and it's working through USB3. I know on mine, when I tried it in Linux (can't recall if I did under Windows), it was extremely flakey there too. The Note Pro just autodetected it, but still copied slowly. I'll have to try that under Windows as well now.

Yes, you may want to update your BIOS.
(For the record, I'm using an Asus N76VB with the factory BIOS, no issue).
Hm, maybe a silly suggestion... Are you using any type of USB charging setting? I know some of these Asus motherboards come with an option to overvolt the USB port to enable fast charging.

Not related. A USBport doesn't supply enough amperé to register as charging. Even my old Galaxy Tab 2 10,1 has that issue.

I have that issue with my Note 3 and even my TF700T since day 1. It's an MTP bug. And now since 4.4.2 I can't rename anything on my Note 3 without explorer.exe crashing. Different pc's, different OS's, different cables, no difference.

I did read somewhere that Asus AI Suite (program to tune up voltage or something for usb charging) can somehow do "harm" to USB3 connection, but I don't have that one even installed.

The funny thing here is like I said: My Note 3 works perfectly when plugged to USB3, but my NP doesn't like recognize that it's plugged to 3.0 port. It just acts like using 2.0. Same PC, same cable, different device.

Yeah, I know mine isn't charging because I watched, even after plugging it into my computer, it slowly go from 70% battery down to 65%.
When looking at what is hogging all the battery, it's the retarded Indexing service. I'm still in the process of seeing if there's a fix for that, but it really seems like it's having an issue (which would also explain why mounting it on the computer is flakey, since they could be trying to read the same file systems.) Oddly, my Note 3 doesn't have any of these issues (except actually mounting as USB3). In fact, I was starting to suspect my PC at work had crap USB ports, but it's just the stupid Blackberry cable (it only successfully charges the blackberry, not my Note 3 or anything besides my mouse that I've plugged into it.)

USB Device not recognized / No fast charge

So I've had my S7 for around two months now, and all of a sudden fast charging just stopped working. Thought, oh, must be using the wrong cable (have loads of them micro USB cables floating around)
Now I'm certain I'm using the official Samsung fast charge plug and cable that came with the phone, and still no fast charge. When I try to plug into my Windows 10 Desktop or Laptop I have a message that says the device can't be recognized
Phone has already been rooted and flashed with a custom rom. Didn't think that was the issue as it wouldn't even show the mounted storage in TWRP, or identify the phone in ODIN.
Now I've flashed back to the stock rom that I made a backup of when I had the phone, and I still have the same problem!! Can't access internal / external storage using the supplied USB cable and can't fast charge.
I'm thinking the USB port on the device is just knackard.. but really, I've looked after it so well I fail to see how this could happen, unless it's a common fault.
Might just get a wireless fast charger, but do you guys have anything else I can try before giving up on the USB connectivity?

try to connect to a different pc, if same it means your usb connector is faulty

Sounds more like the cable is bad tbh, you won't get fast charge from a PC USB port, only from the Samsung charger
But if the device isn't recognised by the PC, and won't fast charge from the charger, the common thing between them is the cable
Possible it's the phone USB port, but more likely the cable is bad
Afaik certain cables can not fast charge either, so chances are the ones you have lying around that are not the official cable can not support it
Genuine Samsung USB cable is white with the USB port symbol on both ends and the phone end has two small ridges to grip when inserting and removing it, should help identify it

Yep I'm using the official cable and fast charger
I'm trying to fast charge via the fast charger and not USB. Only trying USB to access the internal / external storage.
Tried on my desktop and laptop and both have the same issue where my old HTC m8 connects without any issue.

To fast charge I've tried the original Samsung cable with the fast charge plug.
To connect to the PC I've used x3 different cables that all work with my HTC one m8. With all of them I get device not recognised. Already tried installing Samsung switch and reinstalling drivers which didn't work.

I mean for the HTC, does the Samsung fast charge cable work to connect to the PC?
Does sound possible the phones USB port is faulty if you can't get any connection at all to the PC with multiple cables
Try changing the USB mode in developer options
Networking > Select USB configuration

Yep the genuine Samsung cable works when connecting the htc to the computer.
I've tried enabling USB debugging and switching between charging, MTP, PTP, RNDIS, Audio Source and Midi.. all of them come back with the windows popup

Unfortunately it is starting to sound like the phone is at fault
Still under warranty? (KNOX 0x0)

Unfortunately not. Well it's been rooted and flashed so I guess not.
Ordered a wireless fast charger so hopefully that will see me through and WiFi network for file transfers.
I reckon the USB port will need replacing but I'm not really inclined to do that myself.

Just noticed you said you flashed back to stock using a backup you made
Have you tried stock using ODIN and 100% stock files, using CSC to reset?

My dad has a5 2016 with the same issue, and no warranty. I bought flex + connector , replaced it and still nothing. No fast charge ( it takes cca 4hrs to charge it fully ) and no usb connectivity. I gave up on that

@ClowsTyle
Any luck? I seen your recent post in another thread and it sounds like you tried to replace the USB but that didn't work.
I'm having the exact same issue now. Device suddenly stopped fast charging, Windows does not recognize it when plugged into PC. I ordered a new cable to double check and also tried on different computers. I also tried reinstalling drivers, but nothing has worked.

Hi my is doing the same thing no Fast charge and no pc connection, did anybody find out what happen with yours ?

You have to change power ic s535 for s7 edge.
When usb gets moisture power ic will damage.

I have same problem my phone charging 0-100 6hours but ı install notorious kernel and it takes 3 hours it is better than 6 hours

Same Issue
I've had the same issue for the past 3 weeks now and I've tried everything I know...
1. Tested cable and charger with another S7 and they work fine.
2. Factory Reset.
3. Changed the USB port chip.
4. Turned on "Low Battery Dump".
So far, the issue hasn't changed.

was this issue solved?
I´m having same issues whit my galaxy s7 active, I can not fast charge my phone no matter what cable I use, then noticed that evrytime I plug it to any computer it says the devicescan not be recognized, I´m about to buy a new charging port and install it, but I want to make shure this is not a software related issue.
I´ve tried several cables and several laptops/ pc´s
I´ve factory reseted my device and turned on low battery dump, wiped cache partition, and problem still there...

The charger could be faulty/damaged did you try a different charger?

I also have the same issue with my phone the phone charges but not recognize and also tried to change settings on phone and nothing? And my other samsung phone works and nothing wrong with USB tried to install smansung drivers on PC and still same issue.
I tried a different USB and nothing works and different ports on my comp.
My ports works with my other samsung phone so not sure why not with the S7?
Is the USB faulty?
