Hi.
When I connect Pixel C to PC, PC does not recognize it and it does not appear even in device manager. (Even "unknown device" doesn't appear)
And my Pixel C says weird message "USB supplying power to attached device", which I haven't never seen. I attached screenshots of that message.
And what is worse, charging Pixel C is also very unstable. Sometimes I can charge, but sometimes I can't charge.
Of course I can't use adb command. However, strangely, I can use fastboot command in bootloader.
I thought there was physical issue in USB type C terminal because even charging was unstable.
However, the fact that I can use fastboot command means there isn't always physical issue in USB terminal? I'm confused.
I tried several kinds of USB cable, but same result. A weeks ago, there wasn't any problem in my Pixel C.
Please help me! What is the problem?
Pixel C's USB terminal has broken? I don't want to believe, though.

Asking the perhaps obvious, like when someone's car doesn't start "Do you have fuel in the tank?", did you select Use USB for File Transfers v Charging in the pull down? Also, to use ADB, I had to update the driver to a Google driver (been awhile and don't recall exactly which driver).

Adding onto this, it sounds like your tablet is attempting to supply power to your PC. Make sure its in MTP mode. Mine also works in USB for charging mode, though I run Linux.
Are you by any chance connecting by using a USB C to USB A female adapter/cable and then a USB A To USB A cable? If so (I'm no expert) then I think that the wire used in USB C to negotiate "which end supplies the power" will be grounded in the female A socket (no relevant/equivalent terminal in USB 2/3 ) and this tells the tablet "you supply the power to me"

hi there,
I have two (potentially related) problems, the power draw of my desire is immense, from a full battery I get 3hrs tops (in airplane mode). Even when plugged in I don't get much longer i receive a message saying that the power draw is too high.
I have tried restoring factory settings a few times, 3 different batteries and an external charger.
I thought it might be worth trying a custom ROM to see if that helps but i can't get the phone to connect to the computer, it appears to "charge" when plugged in (although still with the above problem) and when i enable USB debugging it senses that there is a cable plugged in and says "USB debugging connected" but the computer can't see it and the phone never asks what i want to do with it when it's plugged in. I've played around with all the USB settings on the phone, tries 2 different cables, 2 computers and both winXP and Ubuntu.
any ideas?
Liambass.
Hi all, I've been lurking the forums since bout September of 2012. I haven't really been posting here, mainly just gathering ROMs, kernels, help etc.
Anyways, my Nexus 7 isn't being recognized by Windows 8, Windows 7, Windows Vista, or even Ubuntu. this leads me to belive this is caused from the tablet. I have installed numerous drivers, but with no luck. Recently, I noticed when I boot into recovery, and the tavlet uis on the Google screen, my computer recognizes it as, "Unknown Device." Soon after it passes the Google screen and boots into TWRP Windows can't detect it anymore. My tablet says it's connected via AC, not USB - which is probably why I can't transfer files. I have MTP checked, and I tried PTP too. I've tried enabling and disabling debugging with no luck still. I'm using the OEM charger for the device, and I have tried using multiple cable with no dice.
"So a new possible way of fixing this after having contacted Asus support. They had me turn of my Nexus 7 and then hold the Volume Up + Power button for 30 seconds and then hold only the power button for 60 seconds. I was told this is to remove static from the mother board. USB Charging, USB Transfer, and Wireless Charging (which is what made me notice the issue) now work. The only problem I have now is that the cord that came with the tablet seems to be a bit loose and will cause it to stop charging when I don't just let it sit on a table."
That was suggested on a different forum, but that didn't work for me neither.
ADB nor fastboot cannot see my device as well.
Any help?
have you tried plugging the cable in to a different usb port?
What drivers are you using? Try the generic USB ones here, which I use with no problem at all: http://developer.android.com/sdk/win-usb.html
For best results, go to Device Manager first, set it to show all hidden devices, then delete (not just disable) any previous drivers you may have installed.
"They had me turn of my Nexus 7 and then hold the Volume Up + Power button for 30 seconds and then hold only the power button for 60 seconds. I was told this is to remove static from the mother board."
I feel like hitting my head against a brick wall when hearing such advice.

Yes, I've tried USB 3 ports, and USB 2 ports with no success.

Gotta love Asus' tech support.
Try Nexus Root Toolkit, it has a nice walkthrough that shos you how to first uninstall any existing non-working usb drivers. Then just try its options one by one and you'll have working drivers in minutes.
I gave up even trying to get my original N7 and my N7 (2013) to be recognized by any PC. What I do instead is use a free app of the day I got from Amazon a while back called Wifi File Explorer. Run the app and you can access the file system from your PC. Upload, move, copy and create folders.
It's worked for me for a while now. I'm sure there are other free apps that will do the same.

Have you also tried usb ports on the back of the PC? Those are directly on the motherboard, whereas usb ports on the front of a PC are almost always via a usb hub connected to the MB. I know of instances where this makes a substantial difference (device being recongnized or not). You might try it (if you haven't already).
Edit : also try disabling AV software and possibly firewall. But admitedly I have personally never had any issues regarding device not recognized due to this.
This was my solution.
Hello dear.
I have a problem with my p601,
I cant connected my tablet to PC.
When i connected, just charging and no any connection.. In odin or storage not show a device, adb not connected...
And when i used a charger show an red stroke on battery icon. And charging is very slowly, during night only 50%.
I'm root my device, install twrp, and install cyanogenmod, but nothing change.
Now whats your idea? How i can fix this issue?
This may be an obvious question but have you tried a different cable or charger? I always found running on stock ROM that charging was an issue unless I powered it down. I have used a 12W Crapple charger and that seems to work ok but charging has never been an endearing part of the this tab.
So in Odin you it doesn't work? Could you have some dirt or contaminants in the USB port, start with the obvious, change the cable, use a different usb on the pc or try another pc altogether.
I had same problem, i noticed that the usb port was loosen little bit, i had to open the tablet apply small pressure with plier to afjust the usb port,,,, and now it's perfect.
So I was going to unlock my boot loader and do all the fun rooting things now that Magisk is working, and when I got to the point of entering fastboot to run the necessary commands, it would just reboot as soon as I entered fastboot mode. To be clear, I turned off my phone, waited a bit, power+vol down, saw the fastboot screen for <1 second, then it started booting.
So I tried unplugging from USB, and could get into fastboot fine, and stay in it as long as I wanted selecting whatever options I wanted, then, as soon as I connected the USB cable (that came with the phone), it would reboot.
So I did a factory reset, didn't set up a pin, fingerprint or anything similar, same thing, about a half second of the fastboot screen, then a boot screen.
I tried booting into fastboot with adb, same thing.
I'm not sure what is happening here, and I've never had this kind of problem before. Anyone have any advice?
I would try using a different cable, and/or a different USB port. I've seen and experienced it being very picky.
My new rig I built has us 3.0 on the front and 2.0 in the back, my pixel absolutely hates being plugged into the 3.0 port, when I plug it in, it does nothing but spam connection/disconnection, once I plugged it into a 2.0 port it works fine
If you are using any kind of hub or extension cord remove them and plug in directly to the PC. I had this problem on my 1st 2XL but so far the 2nd hasn't given me a problem. I did move my PC closer to my desk to eliminate any extensions I had.
EDIT: I'm using my old USB cord from my Pixel 1 plugged into my USB 3.1 port.
Ah, I only have one USC C cable and one USB C port. I'll grab a USB A to C cable after work. Will update in about 9 hours.
Thanks!
USB A to USB C cable did it. Thanks for the help!
My Pixel XL USB preferences is stuck on charge and my USB C to C stopped working and I can only charge using a USB A to C charger & cord. When I hook it up to my PC, it's stuck on charge and no way I can change that, so I can't transfer pictures or update phone. Has anyone experienced this or have an idea how to fix this. Any help is appreciated.
I have the same issue with USB C > USB C not working.
USB A>C works correctly, but I've tried several factory C>C chargers and none of them work... I think it's a software bug.

I think you are right about this issue. Somehow my USB preferences stopped working. It's like the software that controls our issues got wiped. I looked online and it seems quite a lot of people has same issues. But not one has a fix. Mine is stuck on charge only, when plugged into PC, it will only charge. When I plug in my Nexus 6 into PC, the USB preferences works correctly. So I'm still stuck, even plugging in a USB Otg device into pixel XL, that doesn't work either. If you come across a fix, please let me know. Thanks
