[Q] Transformer USB Cable Issue

I've been searching for days for an answer to this and I can't find it. The biggest issue is that every time I plug my TF101 into my computer, I get Windows' wonderful "One of the USB devices attaching to this computer has malfunctioned" message. I get this using the OEM cable and brand new after-market cables. I've found a lot of different forums with similar problems but my symptoms list is different. Here's what's going on:
* The tablet charges just find through all of the cables despite not connecting properly through the computer.
* The dock (keyboard) works without issue and charges properly.
* Flash drives work properly in the USB ports on the dock.
* Android phone (Razr MAXX HD) recognizes that it's plugged into a device, the tablet briefly acknowledges a device (quarter of a second) but then stops reading the phone is plugged in.
* Maybe of note or maybe another issue, it doesn't want to connect to bluetooth devices, either. It recognizes them but refuses to connect.
* Everything is stock.
I've tried a hard reset and deleting every driver associated with the device properly installed and not. I don't have another computer to plug it into so I can't test that. I fear it may be a hardware issue but I don't want to resign to hardware issues but rather definitively know that the issue is a hardware issue.
Any thoughts?
Thanks,

Linux emulated through VirtualBox, see if that detects it.

Tried it through VirtualBox with Ubuntu and another system (mine is Windows 7 Pro, the other system is Windows XP Pro). No dice on any of them.

My thoughts - bad USB cable.
You probably will say - BUT IT STILL CHARGES....
Yeah, mine does that too. But, one of the pins needed for computer connections is shorted. I used my cable 3 weeks ago to ADB, then last week nothing (trying to ADB to do the Ubuntu Touch resolution fix). Got a new OEM cable (and wall wart) from Office Depot, all better.

Virtualbox/ESXi/VMWare etc... I've had problems with all of them even in USB bridging mode. Nothing beats native.
Make sure the right drivers are installed; remove (not deinstall) completely the current ones as they may be corrupted and redownload ASUS Pad PC Suite from Asus' support site for your OS version, I believe it provides more recent Asus drivers (not 100% sure).

Also try the Universal 'naked' drivers for adb, I always have used those and they work flawlessly, and I included them in my peri tool because of this..

Here's where I'm at:
Don't have access to another OEM cable (hopefully fixing that in the next couple of days) so I can't test that. I did, however, install Ubuntu onto my system natively, plugged it in, and got zero response from the system using every cable that I have. I will buy that drivers may cause erratic behavior and such but not having the system recognize that a device was even plugged in makes me doubt the driver issue.
Thank you all for responses. I'll get another OEM cable and cross my fingers that solves the problem.

Just FYI, I know it's not convenient because it takes a month to get it, but I bought this cable and it works fine for data and charge. No need for an overpriced Asus branded one.

I've run into this problem with another device on my PC. Turned out to be a double whammy: the USB port on the PC acted up; and the driver for that device was partly corrupt. Tried it on another USB port to find out. It's not always the cable.

3 ports later I decided it wasn't a port issue (but I do appreciate the sentiment; I've been there with devices in the past).

I had the exact problem lol, I thought my cable went bad, I order another and threw that old cable away... damn what a bum, all it was was just the driver? Not sure, but when it does find the drivers and tried to install it, after installing the drivers knocked my wireless Ethernet off and disable too.

Still no dice
One, thanks everyone who has tried to help this out. I'm not tossing out "Thanks" yet because nothing has worked but I am thankful that people have tried.
Two, here's what I've done thus far that hasn't worked.
* Uninstalled and reinstalled (including fully deleting) every driver known to work with this device (including naked drivers). No dice.
* Uninstalled the driver while it was still plugged in and scanned for device changes. No dice (but this got me the closest; it "successfully" installed an "Unknown Device" and had me restart the computer).
* Used peri and hoped it would magically work after it installed the Naked drivers. No dice.
* Went through "[GUIDE] Getting ADB Setup; An Idiots' proof guide on getting ADB working for Rooting!" (no linking for me yet) hoping I missed something when I was installing. No dice.
* Installed Ubuntu and tried from the other operating system. No dice.
* Plugged into a Windows XP computer. No dice.
* Purchased the recommended cable. No dice.
* Prayed that it would work. No dice.
I'm stuck. I thought about sending it to Asus to have them repair it but I've not heard wonderful things about their repair service and I can't be without it for longer than a couple of days. It just frustrates me that Windows knows I've plugged something it but it simply refuses to recognize it, like it's taunting me into staring uselessly into a computer screen for hours without any solution (and hampering the work that actually means something to my life/career/marriage/etc.)
Any other thoughts? The only thing I haven't tried it is installing the drivers to plug it into my fiance's Mac to see if it will magically recognize it. I just wish I knew for sure it was a bad port on the bottom so I knew that I had to send it in to get fixed...
Thanks again!

PC connection

Hello all. I have a problem that is not unique, but I cannot for the life of me seem to fix it.
My S6 will not stay connected to my PC so I can transfer files, use Kies, SmartSwitch, or anything. Sometimes I hear the Windows notification that it's plugged in, but even when I do, it goes back and forth between being recognized and not. Most of the time it doesn't even show up in Device Manager.
I'm currently running Windows 10, but it did the same thing on Windows 8.1.
I have downloaded the Samsung USB drivers as well as allowed Kies and SmartSwitch to install them.
Thinking my Windows 10 being upgraded from 8.1 without a full wipe carried over whatever problem was in 8.1, I did a full wipe of my PC and reloaded Windows 10 clean. That also didn't help. Note: when I first installed Windows 10 clean, my PC didn't recognize my phone at all. It just acted like a charger. After I installed the Samsung USB drivers, it started making the 'connecting' and 'disconnecting' sounds. Also, the most I got Windows to recognize my phone was for about 5 seconds, and that was right after turning off USB debugging. But with it on or off, it still won't stay connected.
And yes, I've made sure (when the phone has connected for a second or two) that it was on MTP. But... I've tried the camera mode as well.
This makes it not only impossible to move files easily between my phone and PC, but also to use Odin.
I've read many posts where people have this problem, but everyone just tells them to go download the Samsung USB driver, and after having done so three different ways, I can say it doesn't work for me.
Anyone who could solve this for me... well... I'd be willing to donate a bit of money to the cause of your choosing, including yourself.

No one else has experienced this or is willing to shed some light on this?

When I had that issue with my nexus 7 I switched out the USB cable for a different one. Seems to have improved.

Try downgrading to windows 7. Before you connect your phone to the computer install necessary drivers, samsung driver and kies. Use USB 3.0.

Yeah, I'm definitely not going to downgrade to Win7. That would be 2 Windows versions ago for me. I've installed every driver available, from Samsung's (with and without Kies) to Google's universal Android USB drivers, and none have worked. I've also tried USB 3.0 and 2.0 ports (I have both on my laptop).

Hey, did you try connecting other usb devices to your pc to see if they connect? furthermore, you should also try to connect your phone to another pc to check if there is a USB port problem with your PC/Phone

For me the standard USB cable gives this problem, with another cable it works perfectly. So try another cable
Sent from my SM-G920F using XDA Free mobile app

Hi, everybody.
May you help me, please? My S6 SM-G920F, also is not recognised by windows 7. Smart Switch say S6 dont connect in emergency mode. I supose they means "emergency calls only", is that? I had bought the phone locked to O2 but I live in Portugal and I have no valid O2 SIM card. I bought an unlock SRS by TomMobile because I dont knew that needs a USB cable connection. What can I do, please?
Thanks in advance. AS

iphone and Samsung S6 same issues
Hello wvcadle,
I have the same issue and it is quite frustrating. Did you find a solution? As some additional info for you. My i-phone was doing the same thing on my computer. I thought it was the phone and I upgraded to a Samsung S6. It does the same thing as the I-phone, what you described and it works fine with other PCs. SO must be computer related. My bet is windows and my IT recommend a full wipe and reinstall of windows. We run Windows 7 Professional.

its not usb port or cable problem... this problem starts when someone trying to root ... & damage efs partition..

Its just Cable problem my friend.
Find and buy a reliable usb cable. You stated all options and fixes but you never been able to speak of your cable
For those whose saying that root and damaged efs will affect your phone connection to your pc, he's wrong . Rooting and corrupted efs partition doesnt have to do with windows driver etc.
Just think out of the box.
If it did not work with your pc. Then switch to other pc with smart switch & samsung usb driver installed.
I prefer installing samsung usb driver and then smart switch.
If it didnt work, try using different cables.
If it didnt work again, use other samsung phone and see if it connects.
And so on ...

Having exactly the same issue...
Started just today (yesterday and previously no problems experienced, phone would just connect & be visible and available for data tfr, no problems). Today, no go. To be clear, it's Galaxy S6 128 gb running Lollipop, which no longer connects for data tfr via USB to laptop running win7 ultimate. It only connects and charges. I have checked for updates for both windows and Android. There are none outstanding. I have downloaded & reinstalled samsung USB drivers on laptop. No change. I have tried 4 different USB cables, 2 new, and the cable supplied with phone. No go. I have tried these cables in all USB ports on laptop. I have tested other devices in all USB ports and connectivity to laptop with other devices is fine. I have tried connecting phone to another PC, same issue (only charging). I have done the developer thing and switched USB debugging on, no change, and off again, rebooted both devices multiple times, all with no change. Yesterday all was good, today - nada. Anyone got any other suggestions?? Wit's end, reached.

It's been said many times already, but I had this problem and it was the original white cord that came with the phone. It would not stay connected to my laptop nor would it stay connected to the charger. It sat there blinking and making the charge cord inserted sound when plugged into the charger/computer. I changed cables and it went away.
I remember picking the phone up one night in bed and forgot the charging cord was attached. I reached the end of the line and it yanked out of my hand and fell to the ground. This is the only thing I can think of that damaged the cord. I was lucky it didn't damage the charge port on the phone. So you could have a screwed up charge port on the phone if you've tried new cords with no avail. I wouldn't encourage it but sometimes the charging fin can be bent back into place to make a better connection....had to do this on a dell tablet.
Also, if you're using lock screen or fingerprint, I believe you have to unlock the phone after connecting to PC to access and transfer stuffs - just a thought.

Thanks for the input - it's not a lock screen issue - I've tried connecting with screen locked (then unlocking when connected) - and connecting with screen unlocked, and I don't use the fingerprint security option. No changes observed. I have had concerns about the charging fin, but I am always careful connecting and careful with the phone generally - it looks OK and I'm rather loath to start bending it about in case I just f**k it up entirely. At least it still charges OK. Looks like I might have to bite the bullet, wipe it and take it to a Samsung repair centre. At least it's still under first year warranty. Thanks for your time talroot.

Original white cable did not work from day 1. Fast Charging is working fine but USB connection and tethering is a hell. You need a new cable and a good quality, not some cheep stuff.
Samsung really disappointed me because I owned many of their devices and most of them had some small issues, but after this in s6 edge and overheating issue (especially when using Gear VR) I will not by from Samsung anymore.

just for the record....
...my phone started connecting to laptop again. After about 3 weeks of non-connectivity, I connected again to charge and *ding* it was an external USB device once more. Same cable as before. Doesn't make any sense, but there it is. Thank you everyone for your input.

USB Problems

My computer for some reason reminded itself of not recognizing my Idol 3 5'5 6045k. Two days ago it was all fine and now everytime i connect it to the computer it only charges. I've tried everything from changing usb cables to unistalling andthen installing the device drivers, enabling debugging, restaring either smartphone and computer. Everything I can think of. Please help me out, I'm trying to root the smartphone and without it recognizing I can't do anything, not even transfer files. :crying:

Obvious Question #1: Did you check the phone notification dropdown area to verify the phone is in MTP or PTP mode so it will show up on the pc? As for transfering files...you do have the option of loading up a microsd card with whatever files or installing a wifi adb app to connect wirelessly. You could even use an app like airdroid to let you do all sorts of things.

Therre's no notification after connecting the usb, it just charges the phone, seriously, I've tried everything to enable MTP but nothing does the job. And what do you mean by using an adb app? Can I root my smartphone by a wireless connection?

You are overcomplicating things. 1st...there is ALWAYS a notification in the dropdown that says what mode the phone is in....mtp, ptp, charge only or "cdrom mode" which installs the usb drivers. Pressing on that notification allows you to change the mode the device is in.
As for rooting....all you need to do that is to flash or boot TWRP (details on booting it are in the system image thread) and then flash the supersu zip from inside twrp to your device...reboot and done...but I think in the newer TWRP's they even offer options to root automatically...ie the zip is already built in. After rebooting to your phone you install the supersu apk from google play so you can configure what apps have superuser access.

Your telling me when the phone is plugged into the pc you don't see the notifications below or some version of them at all? If so then you need to fully uninstall the devices in device manager including remove the drivers...then use the drivers in the system image thread (since you obviously can't use the ones from "cd rom mode" which would be the best solution). USB debugging isn't even an issue yet...your phone should still show up to the pc as a camera device (ptp) under just about ANY scenario using even built in windows drivers.

Have you tried a different cable? Perhaps that one is damaged or is only setup for charging? Only thing I can think of.
And then I realize you mentioned that Not sure what else would prevent it from giving you those options.

I'm also facing similar issue after the 2 update. Were you able to fix this?

Something as little as a Micro USB cable can cure a lot of problems. It needs to be a well built one by a known manufacturer to avoid problems.

Actually I've been having pretty good luck with the $1 ones from Dollar Tree but the key is certainly to try multiple cables....on some the microusb plug will make it difficult to get a solid connection especially if you have a case on the phone.

You may be missing the point of "trying" different cables. It's not so much the "quality" of the cable, it's the fact that some cables are for "power only", and "will not" transfer data, regardless of how hard you try.
You need to be using a "proven" data/power cable, otherwise your beating your head against the table for nothing.
Just to add, I put a piece of red tape on all my usb cables that are power only, no guess work.

I own idol3/moto g 2015 and s3, have no problem with other 2 device. I'm having this MTP issue after the UE40 update. Verified in all 3 OS, adb is detecting the device but not MTP/PTP. Idol3 support is not worthy responses.

Well, USB works fine here, and I've had 5 different rom's, 2 Canadian, 2 US, and the Chinese rom, on this phone without any USB issues, sorry, can't help any further.

After a complete wipe and restore, it worked.

My computer for some reason reminded itself of not recognizing my Idol 3 5'5 6045k. Two days ago it was all fine and now everytime i connect it to the computer it only charges. I've tried everything from changing usb cables to unistalling andthen installing the device drivers, enabling debugging, restaring either smartphone and computer. Everything I can think of. Please help me out, I'm trying to root the smartphone and without it recognizing I can't do anything, not even transfer files. :crying:

I had the same problem as well. It only showed charging when I plugged in the USB cable. Tried switching cables, turning off and on USB debugging but nothing worked. I finally just rebooted the phone and then it worked again. Strange that it suddenly stopped.

I have a different issue; the different USB modes work fine but I don't have the 'cdrom' option in the USB mode dialog. I've tried various Alcatel ADB drivers that I have found and none are working, using Win7 64. My Idol 3 4.7 is 6039I (US).

Answered my own question, simply install the Mobile Upgrade Q software.

nope, doesn't show up. it's a bug. i had it before, googled until i found a fix and got it working, now it's back to not being recognized. nothing shows on drop down menu.

No USB Connection

Today, looking at the storage left i noticed i had only 12.55 instead of ~25 (my N5 is the 32gb model) and i tried to reset the device following a guide. Easy, right?
No.
The device didn't connect to usb, i tried 3 different cables, on 3 different pcs, with and without drivers, uninstalling and reinstalling them, even reinstalling windows on a machine. Nothing.
I thought it could be the OS, so i changed rom(i put on Cataclysm 6.0.1) but the situation was still the same.
I even tried to mount the storage in TWRP but no signal at all.
Not even fastboot. Only charge.
You are my only hope, please help me.

What guide did you follow? A factory reset is not called for yet.

second post, how to turn back to 32GB.
https://productforums.google.com/forum/m/#!topic/Nexus/6lMKqYYXpXw
here some suggestions on the usb ploblem, didn't work.
I also tried the driver guide from NexusRootToolkit, resulting in a 30 second connection recognized by the phone but not by the PC, a laptop running Win8.1.
i didn't include 3 other threads on XDA that redirected everyone to a common troubleshooting.

While plugged in, swipe down from the top and change usb charging to usb for file transfer.
Is that what you are wanting?

There is no signal AT ALL, no choice between charge and MTP, no devices in Device Manager on windows, nothing.
I tried turning on debug usb, no signal.
Tried forcing MTP in developer settings, nothing.
Only one single time i heard the classic windows sound telling me a device was plugged in but there was no phone on file explorer and the phone was only charging.
It's only charging now.
UPDATE: turns out the FLEX connector is the real problem since the screen went full retard and now looks like this http://forum.xda-developers.com/google-nexus-5/help/nexus-5-screen-colorful-static-t2600032

Unable to have phone recognized as a device on any computer

Hello there! I posted in the N00B thread without any success and so am casting a wider net:
I have a rooted phone that's been working well for about 1.5 yrs and all of a sudden it's not able to connect to the computer via USB. It was working fine til about 3 months ago, no new apps or changes to the system as far as I know. It still charges when connecting to the computer but I don't get the prompt to choose the USB mode and the computer doesn't recognize it as any sort of device. I've tried it on several computers that have recognized it in the past without luck (drivers up to date) and have tried different USB cords.
I've gone to USB and developer settings and changed and restored default settings for USB connection as well as toggled a bunch of other settings in that section.
I've wiped the Cache and Davlik Cache several times.
I cleaned out the physical port. Any other thoughts? thanks!

If you are on windows 10 PC, the latest windows updates could be an issue. I faced the same issue with my computer. After rolling back windows update (or may be resetting the PC to default settings) has helped resolve my issue and i could connect my phone again normally. It is nothing to do with your phone as far as i know.

You said the drivers were up to date but you didn't say whether you tried completely uninstalling the drivers. If you didn't, uninstall every driver you can find related to the Honor, reboot and plug the phone back in. I'm running the absolute latest version of Windows 10 and have no problem connecting my wife's Honor 8.

Thanks for your suggestion - I did try rolling back the update without benefit. Also, to reiterate - this is not being recognized by several computers (including a Mac) and that leads me to believe that it's the phone that's the source of the issue. I don't even get the USB menu (Charging, MTP transfer, debug mode, etc) when I plug it into several different computers.

It may be too obvious but did you try another USB cable? If it's not the cable try this with the default dialer *#*#2846579#*#* then select in background>usb hisuite, connect the cable and see what happens.

I have tried different cables but no suggestion is too obvious! My sister in law actually also has an Honor 8 and her cable on my laptop is recognized, so that's what I've been using to troubleshoot with my phone. I did go into that menu you suggested and I tried toggling HiSuite, Manufacture, and Google and exit the menu and still nothing when I connect the cable (other than charging). Thanks

Have you played with any of the developer options like USB Debugging or USB configuration...... Nevermind, just re-read your original post. I was almost sure the dialer thing would fix it but if a reset won't I'm at a loss. I still don't think that it's a hardware problem but I guess it could be. There are things like wiping the cache partition that I see some folks have used for various problems. That would be an option that wouldn't affect your apps.
