USB problem - Shield Tablet Q&A, Help & Troubleshooting

I have spent all day trying to connect my K1 to a PC - absolutely no luck at all - Not Recognised.
I have tried many different cables. I have tried 3 different PCs (all Win10).
I have ensured USB debugging is on & MTP.
I have factory reset it twice.
I have the latest Nvidia USB drivers installed on the PC of course.
I am starting to pull my hair out! Whatever I do Windows reports Device Not Recognised.
I am beginning to think that the USB socket is faulty. It charges perfectly, but is DATA actually getting through?
I have just tried an OTG cable and it just ignores it and won't access memory stick using it. This seems to reinforce the idea of a faulty USB on the K1 as far as data transfer is concerned.
Any suggestions would be much appreciated.

When tab is connected - slide your finger from top to bottom(open notification panel), tap charging, change to mtp/file transfer

Thanks, but....

Thank you very much for taking the trouble to reply. I cannot follow your instructions though.
When I plug in a PC, the tablet gives the 3-tone sound, but there is no notification in the panel. The battery icon just changes to show a lightning flash across it. The word Charging does not appear anywhere. Tapping the battery icon just takes me to the charging graph etc.
Am I being stupid?
In Settings/Developer 'Select USB Configuration' is set to MTP.
ANY suggestions would be very welcome. Thanks again...

Settings / Connected Devices / USB / Transfer Files.

What PC connection function are you trying to use? Is it internal storage, or adb, fastboot, etc.?

Thanks for your time.
In fact Nvidia eventually accepted that it was a hardware problem and 2yrs 10months into warranty, sent me a replacement.
VERY happy with this service.
Replacement now running Lineage 14 - much improved.
Well done Nvidia!

PC Connection

Hey all, I've had my Captivate now for afew days and I'm loving it, but today I ran across an issue that's driving me crazy.
For some reason when I connect it to my PC I'm not longer getting the Mount SD option on the phone and can't look at my files. I've enabled USB debugging and tried it. I've told it to come up as Mass Storage and tried it. I also told it to Ask when connected and it's still not working properly. The drives show up in Windows but cannot be accessed. I also no longer get the USB notification up in the notification bar.
The weird thing is sometimes if I restart the phone and connect it everything is fine, but then if I go to do it again nothing. Anyone have any suggestions?
Biggest misconception here is that its random, it isn't.
Download kies by samsung and update it and you will get the right USB drivers installed automatically.
If you choose not to do that, you'll Vast have to keep trying different ports or restarting.
Its also possible that you may have a faulty wire but this is unlikely.

I've tried it with multiple wires, and when it works it is reliable, but most of the time it's just not showing a USB connection on the phone.
I spent awhile downloading Kies and it's updates and in Mass Storage mode it sees the drives of the phone but doesn't let me use them. I Kies mode it does nothing... This is so confusing...
Go in here download the drivers:
http://forum.xda-developers.com/showthread.php?t=728929
Be aware, they might take up to 15 minutes to install, and no KIE is not included.
Make sure you close all your apps on phone before connecting to PC. Few apps that use the SD will hold the resource and not allow for PC connection.

I downloaded those afew days ago but I will redownload and reinstall again just incase. I think the fact that the USB notification isn't showing up in the bar on the top of the phone is what's confusing me the most. Previously I would see the USB Icon and something would pop up saying I need to mount the drive. I would mount it and there would be no problem. Now I'm not getting that at all and I've tried Mass Storage, USB Debugging, Kies, and Ask.
I've never had a problem connecting my Captivate to my Windows 7 64 bit computer. I didn't install Kies or any drivers either. Not sure what all the fuss is about. I'm suspecting a lot of PEBCAK errors.
I'm starting to think there are some strange power requirements when connecting the phone to USB. Most of my systems have been fine but on one, when I connect the phone to the front USB ports, the USB Wifi adapter on the back simply stops working. While the phone is connected, the computer refuses to recognize the Wifi adapter. A soon as I disconnect the phone it starts working again.
I've seen people on other forums with intermittent issues getting the mass storage connection to work when connected to the front ports on their systems. A lot of times the front ports are connected through a USB hub in the computer case that doesn't deliver full power. If the phone isn't drawing enough power or is shunting power from other devices, this might explain the issues people are having.
Mine is acting up . I used both teh 5.02 drivers from samsung and the one linked here and similar results. In Samsung mode it goes to the Digital Still camera and flakes and on mass storage it shows two new drives..neither of which is writable or readable. This is on a cap with no SD card and XP sp3. I tried different ports but with the same result.
I was fighting with this all day. I installed, uninstalled, reinstalled all the drivers and kies, but, I was trying to connect via media player and nothing was happening. Then I noticed that there was a small message popping up on the Captivate's screen that said something about the device had to be on the idle screen before it would connect and fun the sync software. Tried turning off all running programs and still nothing. Then, I remembered that I had switched to Launcher Pro. I switched back to touch wiz, and lo and behold, it connected right up and allowed me to sync items with media player.
Interesting. I've been using ADW.Launcher and haven't see this problem except when I don't get the cable securely inserted into the Captivate. I even use a Nokia cable most of the time. The Kies Drivers are clearly the most stable. I downloaded the Drivers from the Captivate microsite and found they didn't support KIES, so I just reinstalled the KIES driver for MTP. Everything else works fine on W7x64.
++++UPDATE+++++ Validating MSHampton post
Well this sucks. On my Captivate, unless you are using TW.Launcher and in the idle screen, the Captivate won't launch MTP so you can connect to KIES. The USB Storage mode works with other Launchers (ADW and LaunchPro), but not KIES or Media. I didn't try PC Internet tethering. I switched between the two several times, and KIES only works with TW.Launcher on my device.
Is there anyone who knows of a Launcher OTHER than TW.Launcher that will interface with KIES so that the Captivate can connect? Or can ADW or LauncherPro be "tweaked" for the Captivate? I was just starting to like ADW.Launcher.

Holy crap, I have that EXACT same problem. I thought it was just the fact that my USB Wifi adapter is a piece if crap (which it is).
Just for reference, what kind is yours? Mine is a Belkin Wireless G F5D7050.

It's the Tenda 311U which is also a cheap piece of crap ($15 at Micro Center.) It doesn't look like they use the same chipset.
I've had the same issue as well. Hooking up the Captivate to the front USB ports disables my USB mouse (on the back). I'm not sure what it could be doing that would lock up the USB bus...
Using Windows 7 netbook
I finally got tired of it deciding and put in the mode to ask me when I connect. the problem i am having is when you just charge it, it does not know that it is just charging and wants to go to ysb mass storage or the other screen. also I use double twist to connect to the phone.
thanks
Jon
The best bet here is to use USB ports on the back of the computer.

If you're still having problems, select mass storage and connect the usb (or select ask every time and it will ask when you plug it in). To access the drive like a removable drive, you have to swipe the icon in the top right of the screen and select the usb selection. Then click mount and it should work! I had a hard time with this too and thought it wasn't very intuitive. Good luck!

Yep, strangely enough using the back ports worked. I'll have to see if a powered USB hub will work and then I guess we can conclude that it's a power issue.

I've set it to both Mass Storage and Ask every time and the problem I get is that I only get the USB icon up top sometimes, it's very rare. I've tried this on multiple ports and multiple PCs with the drivers downloaded and sometimes the notification shows up and I can select mount, but most of the time nothing is in my notification bar at all.
I love this phone but I don't understand why it's so frustrating just to connect it to a PC. I've also tried the Kies methods and it sees the phone, but doesn't let me access the files.

This just solved my kies and windows 7-64bit issue. This should be sticked advice or added to the wiki.
USB Setting no PC- Connection
I just got my AT&T captivate and I notice that under application,usb setting I don't have the PC-internet option in there. This is only what I have under USB setting:
Kies(Firmware update)
Media Player
Mass storage
Ask on connection
So, question is, how do I enable the pc-internet option? Any suggestion I really appreciate.

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.

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

[Q] Pixel 2 won't charge or allow data transfer over USB C

The title was supposed to say C-C
As in the title really; When I plug the phone into my laptop (Lenovo ThinkPad L450) with a C-C cable, the following happens.
Some key points in trying to diagnose the issue:
Used three different C-C cables including the one that comes in the box
Tried a USB 3.0 A-C cable on the same laptop, works perfectly
Plugged a HTC 10 into the same port with the same cables, allows fast charging and 3.1 transfer rates
I have been into 'Developer Settings' and changed 'Select USB Configuration' to 'Charging',
Can anyone help, or is anyone experiencing a similar issue? I really don't want to have to RMA this.
for charging i cant really help but for data transfer try enabling usb debugging and getting the right drivers for the pixel 2. also connect as MTP for data transfer.
havent tried any of this myself as i dont need to transfer my files yet and theres no roms either but let me know if it works.
good luck!
I have kind of the same issue - while mine charges, it doesn't recognize the phone for MTP at all. Tried both the cable that came with the device, and the 5x cable I've been using since February. My husband's 5x is recognized, my Pixel 2 isn't. Have to use a USB-C to USB-A cable to do any data transfers.
This ticks me off, because I have 2 USB-C ports on my laptop. One that's a USB-C/Thunderbolt port (which always worked with the 5x), and the other that's just USC-C with USB 3.0 capability, which has my USB hub plugged into it. The hub won't work with the C/TB port, and now neither will the Pixel 2. So I either have to grab my C to A cable to load music and use ADB, or plug into the hub's port, losing my external keyboard, mouse, external HDD, printer, and Wacom tablet.
vido.ardes, is your C port Thunderbolt as well?

Hi all,
I just faced this issue. Connected my Pixel to my PC, no indication of connection either on PC or on Phone, except that the phone was charging. Even the file explorer on Windows 10 wasn't displaying Pixel as a connected device.
I found a solution, I hope it works for you all,
Go to Settings->Apps & notifications->App info->Tap 3 dots in top right corner->Tap 'Show system'.
Then find 'External storage' and 'Media storage' apps in the list and clear cache and data for both these apps. Restart your phone and wait 5-10 minutes before connecting the phone to your PC.
After connecting, the phone should now show 'USB connected for charging', as it did in Nougat. You can tap that notification and select file transfer."

These are the exact steps I did on the Pixel 2:
Settings>Apps & notifications>See all 125 apps>3 dot menu>Show System>Media Storage>Storage>Clear Data (this got the cache, as well)>Back>Back>External Storage>Storage>Clear Data.
Then I plugged it into the C/TB port, and the computer made the "USB Connected" noise, and "USB Debugging" came up in my phone's notifications (yes, I've enabled developer options and USB debugging there.) I'm then able to go into Settings>Connected Devices>USB and choose Transfer Files.
I just cleared the cache, not data for both and it worked.

Now that you can connect to your PC, is there any way I could get you or some other kind soul, to pull the system/framework folder and system/priv-app/SystemUIGoogle folder for me? The system.img files cannot be unpacked at this time. Every method tried gives "List index out of bounds" error.

Thanks for the advice, but unfortunately no change for me. I fear I may have to RMA this, which I really don't want to have to do.
I have found on my other devices, that if I reboot to recovery mode, my computer can then read the file folders in my device.
This appears to be an issue with the laptop, not the phone, as it works on another PC with a USB-C port

Unable to connect to PC in any mode

Hi all, I'm afraid I already know the answer to my question but I'll still ask if there's even a slight chance to get this fixed on my own.
I had this issue on Android 8.1 where my Pixel kept saying "Supplying power to connected device via USB" even without anything connected to it, (it started doing that one day without any reason) tapping the notification allowed me to switch to "Charge this device" and then turn on MTP mode, battery life was terrible but I wasn't that much bothered by it because I am an Android developer so I kept it connected in USB Debugging mode most of the time anyway.
When I got the notification for Android 9 update I decided to update hoping it'd fix the USB issue but after the update it now always says "Charging connected device" and tapping the notification does bring up the "USB Preference" screen and it allows me to switch to "USB Controlled by this device" and it starts charging but there's no way to switch "Charge only" mode to anything else, ADB does not see it, fastboot does not see it and there's no persistent notification on the phone about it being connected via USB at this point (in any mode). My understanding is that this is a hardware issue but Oreo still allowed me to workaround this and get the USB debugging connected.
Is there anyway I can get back to Oreo without using fastboot flash or any other solution to this?
Thanks for reading.
PS. I'm on Ubuntu but I can access a Windows machine if required and bootloader is already unlocked.
I'm curious if you're able to connect to a USB OTG storage device.
I'm having this issue connecting it to my windows 10 laptop.. the cable recognizes it.. starts charging.. shows option on phone to change type of connection.. but not matter which one i change it too, the computer will not pull lit up as a drive to see the files..

Same here! I plug the cable into the Windows 10 computer, I even can change the mode from charging to MTP file transfer, but the device won't show up in the Windows Explorer. It appears under connected devices though.
My Pixel 2 XL would not connect to PC for file browsing if USB debugging of Android Apps was enabled in developer settings. Didn't matter which option I chose to connect. IDK if that is expected or not, but it took me a while to figure out. Happened Spring 2018, idk if Google fixed it.

Couldn't find any OTG cable to try that but strangely enough a few days back I connected it to PC for charging and Nautilus popped up, same cable, same USB port and it started working all of sudden. Did verify with a couple of other cables and different ports and everything is working fine since.
"Charging connected device" notification never appeared again, only thing different (when it started working again) was that I was out of the air conditioned room most of those days, might it be moisture or something like that?
I'm back to my normal routine for a few days now and it's still 100% normal, will have to see if it stays that way.
Sorry for late response.
Here's an update in case someone else runs into this situation, I can say this with 99% certainty that is caused by the blackish residue build-up around the USB port over time. It's not too much that it's visible just by looking into the port but it's enough to make the device behave like this.
Here's what I did to get rid of it, took a match stick (don't use anything metal) and broke it in half making a sharp edge on both broken pieces, took the non coated piece and inserted sharp edge in the bottom side of the port and gently wiggled it around while applying some pressure towards the connector (just a little bit, make sure you don't break anything), did this for about 45 seconds then took out the match stick and the part that was touching the connector had turned blackish (I guess this is when you know you have 'cleaned' it enough?), repeated the same process on the top side of the port with a new match stick piece (guess you can use the same one after cleaning it with a tissue), the only difference was that this time applied the pressure in opposite side (other side of connector), device was on during all this time.
It builds up again after a while (~3 months) so I had to repeat the entire process again when it started doing that again at the start of December but it wasn't that annoying this time because I knew exactly what was wrong and how to get rid of it, device is still working fine 100%.
I'm simply sharing my experience and not encouraging anyone to do this but if you do decide to try this be sure not to use anything metal and don't break the connector inside the port (turning the device off would be a good idea too) and you'll be fine and if something does go wrong I won't be responsible.

Can't connect to Windows 10 PC?

For some reason I can't connect my Pixel 4a to my PC with a USB C - USB A cable (or USB A - USB C, not sure what the official name is) , even though it worked fine on my previous phone.
Included with the phone is a USB C - USB A adapter, but I see no use for it unless you have a special USB A cable which I don't.
My motherboard does have a USB C slot on it and it does read my phone when I plug it in that way but for some weird reason it's really loose and doesn't stay connected unless I keep physical pressure on it.
I'm not going to update to Android 11 until the November update because I've heard the current build has a few bugs, but does anyone know if Android 11 fixed the USB C - USB A issue?
Have you made sure to switch to file transfer mode? It defaults to 'no transfer' mode when I plug into my laptop.
Most likely you need to toggle the phone connection settings to data transfer, originally it will be set to charge only I think.

I had this issue too. Windows file explorer would just crash after one or two files and stop transfer, no matter the size and type. (Yes I had file transfer selected on my phone ?)
Then windows update gave me a driver called "Google Inc. - Other Hardware - Kedacom KDB Composite Interface". I also updated to the newest firmware on the phone. No idea which of these did the trick or if it was the combo. However. Smooth sailing now ??
Hope this helps
(If windows update refuses to give you the driver, you can get it from Microsoft's update catalogue online. A Google search will do)
Ok it's completely messed up. When I search for USB settings it doesn't let me change anything at all, even though when I first got the phone I could and I changed it to transfer files. EDIT: No actually the setting that I changed was a developer option called "Default USB configuration" which I changed to transfer files but that still did nothing.
I just plugged in my phone and looked for the USB setting in the notification area but it wasn't there, but I noticed an option called "manage"
I went in there and noticed this. (see attachments) it's locked to be off and I can't change it. Very odd.

You're in notification settings. Try short tapping rather than long tapping to get the menu to pop up allowing you to select data transfer.
Changing default USB settings in developer options doesn't work for me either.

My point is that the notification that normally comes up when you plug in your phone to a computer to change to data transfer, charge only ect ect isn't even coming up because the firmware is stopping that notification from coming up altogether and I can't change it so it does.

Almost certainly a cable or host port issue. Swap cables and see what happens. Same for hosts/host ports. You're not going to have toggling options if the phone does not 'see' all expected lines/pins.
I had the same issue and changed to a different cord to fix the problem.
You have an non certified cable it seems, I've confirmed this pixel 4a works with only certain cables for usb transfer, also the usb a to c cable you have will not charge the device as well.
Get a cable from know manufacturers like Samsung, it worked for me.
Yeah turns out it was a cable. Strange how my cable worked with my old phone but not with the Pixel 4a
Had this issue with my new 4a just now. Cable was fine, even used the new cable that comes with it using a Usb C to Usb A adapter. Nothing worked. Upon opening Device Manager I found a new device called 'Kedacom USB Device'. After trying random things, I decided to uninstall the current drivers by right clicking on it and clicking 'Uninstall device'. Suddenly the phone connected, and even showed the adb prompt.
So for anyone still facing this issue, hopefully this solution might help
