i searched around and i cant find the thread on this.
i was charging my phone through the USB port and it just randomly disconnected. i reconnected at it is recognized for a second then disconnects. the menu comes up on the screen and i see the notification at the top, but after about 2 seconds it just acts like i unplugged it
i have tried multiple USB ports, cables and different PC's and they all do the same thing now.
i installed HTC sync and rebooted the machine. i changed the power settings on the machine and made sure that the USB power management is disabled.
does any one have any idea whats going on?
Do you have a auto kill app such as taskiller ?

no... the phone was just hard reset. the issue was there prior to the hard reset
it does the same thing on my laptop and desktop
both are windows 7 x46 with HTC sync installed
could be your usb port on your handset OR/AND the usb cable's tip that you insert into the port could be loose/failing. wiggle the usb cord at the end where it connects to the phone GENTLY and see if its loose. should be s snug fit...
I have the same problem n started a few threads about it n havent gotten anywhere. My work computer has no problem seeing my phone but my personal computer will not, very very strange. Ill watch this thread n see if a solutions comes about.
seems like a very snug fit too me...
i should also mention that plugged in to the wall charger it has no problems
i have tried 3 different cables and 3 different computer and all USB ports on those computers, all the same issue
I didn't have this issue till now but suddenly same thing started happening to my phone..
I have plugged in my phone using USB with laptop and it shows me charging but after two minute it just discount it...
me and my buddy have the exact same issue here. what i do is, i unplug it a few times and on the 4th i keep it it. seems to be a bit more stable that way.
i don't think this is an issue with faulty usb ports on everyone's separate computers. (could be but i frelling doubt it) ive tried this in multiple windows machines (win7x64 and xp), and it happened on all of them. Only once did it happen on my work mac. i have not, however, tried a different micro usb > usb cable. i only used the htc one. we could have faulty cables. or it could be a phone issue itself, hardware wise whereas these are the only common denominators we have in this problem that i can see.
i lean towards faulty batch of cables. if you plug in the cable to your phone and computer, and wiggle the middle of the cable without touching the ends, it will disconnect.
what gets me is that there is no problem when it connects to the wall usb port. that is confusing. maybe the cable needs a more heavy flow of power to stay connected, which then leads me to believe that usb drives don't have enough juice to keep the thing going, or at least variable flows of power.
i know the phone has an "issue/feature" where it will stop charging the phone completely when it gets to 100% even if you leave it on the charger. maybe some sort of overcharging fail safe right? so what if there is something wonky going on with the phones usb port, or the phone cuts off the connection thinking your done using it?
its late, im speculating just throwing stuff out there.
I'm getting the same problem. Thing is, if it needed more power, why would it still work in a mac? I didnt have this problem until I went through a few different ROMS. So I dunno. I never had this problem before root. But I dont see any reason why it shouldnt fuction normally

I got my problem yesterday. My phone (GSM version) suddenly didn't charge when I plug with charger.
I try to connect it with PC, PC not recognized it, still not charging.
Reboot to bootloader, all fastboot command work fine (this thing is what make me believe my microUSB port doesn't die). So I flash stock 4.2.2 with Gnex toolkit.
Now the phone charge, adb and mtp work fine when I connect it with PC, and with wall charger nothing happen when plug it in. I did try some charger, it's same, still not charging.
Please help!
p/s: Sorry for my bad english but I hope you can understand what I mean.
There have been issues with the MicroUSB port in some Galaxy Nexus phones. I know this because I was involved with a thread over on the Android project forums having to do with very strange issues of the screen coming on all the time. The discussion is here: http://code.google.com/p/android/issues/detail?id=39625
We finally seem to have resolved the issue by very gently bending the tiny pins inside the phone's MicroUSB port upwards towards the screen.
You have not mentioned the same issue, but I can imagine that all sorts of strange activity could be attributed to a faulty MicroUSB port. You should have a look at comment number 161 in that thread and think about trying that. Be very careful! Be very gentle. If you break it, it;s not our fault! ;=)

I remember I had a similar problem like this and I had to change my usb cable. Now I am using my Kindle cable for my nexus as well :laugh: so just try to change your cable and see does it work
I've been through 3 cables so far. The OEM, an HTC ,and I'm on a generic one now. Works for now
im having a problem connecting my pixel 2 xl to my desktop pc via usb c
here are some things
when i connect phone to usb-c port nothing happnes. no charging, no usb options notification
old phone, nexus 6p, uses same port and cable and works just fine
pixel 2 xl will connect to usb-c port on my laptop just fine
will connect to usb-a port with an a-c cable just fine
if i boot in to safe mode the desktop will recognize but it takes 5 minutes or so of being plugged in
windows 10 and usb drivers are up to date
any ideas??
thanks guys
First thing to try would be another cable and/or another USB-C port.
On the first Pixel XL, after Oreo came out, it very picky about these. It took me many tries of three cables and two USB-C ports until the images would flash properly. Two of the cables were straight from Google, and the third one was certified as a good cable. They all worked fine for everything on Nougat.
I realize that you're only trying to connect it but those are always the first things to try.
I did try other cables. Both work on my 6p that has Oreo. I only have one usb-c port on my desktop unless I buy an expansion card and I'd rather not. I did try my laptops usb-c port and that works
The default option when plugging phone into USB on a laptop or PC is charging. You can see this from notification area.
Select this and change it to File Transfer. Then you should be able to see it connected.
I'm not getting the USB options notification unfortunately

Do you have USB debugging enabled?
If so, then when you first plug it into the PC, you should be prompted on the phone to allow the PC/Device to connect to your phone. Allow it always.
USB debugging is not turned on

That is your issue, you need to turn on USB Debugging to enable communications between the Laptop/PC and Phone. Once enabled, and you connect them. Drop the notification window and select File Transfer.
Have you tried toggling PTP and MTP? That is how I got my Nexus 6P tp bre seen as storage (adb worked fine).
I didn't have this problem with my Pixel 2 XL using the same cable and port.
I don't know if this will have any effect but on the pc, plug to the usb ports on the back that are direct to the motherboard instead of usb headers on the top/front of pc.
I have this issue with a TomTom satnav and a Mio miview dash cam. Unless they are plugged in on back pc / with Windows 10 doesn't recognize

I have been having USB data transfer problems as well.
My Pixel 2 XL sometimes chokes on files when transferring from MacOS with Android File Transfer. I have tried different cables, different computer ports, different computers. I have tried USB debugging and Safe Mode. I have even tried factory reset. Sometimes it chokes on the same files, sometimes it is different files. Yet my Pixel XL handles those same files without any problem with the same cables and computers.
Data transfer stops completely. Sometimes a reboot of the phone is required. Sometimes a reboot of the phone and computer. And sometimes even a factory reset doesn't clear the problem -- it has unable to detect any other connected phone to transfer files during setup.
I was only able to bypass this file transfer problem by sending the files as a zip.
I have contacted Pixel 2 Support about this. They seem very puzzled. They said that I should be hearing back from an "upper level", but that was 5 days ago now.

Same here man, contacted google this morning and support said this was how it was with his brother's phone as well. Had no suggestions.
EDIT: This is with USB Debug on or off, no options to charge or select anything, takes about 5 minutes and then starts working as normal. Unfortunately, the fingerprint scanner stopped working as well. Getting a new one sent out, I'll follow up and let you know if it has the same behavior.
EDIT: 11/6/17 - Got new phone in. Fingerprint issue is resolved but the same USBC issue is not. Phone does charge from it when off.
I've got a very similar problem here with Pixel 2 XL manufacture date October 10th. After some extensive troubleshooting, I'm certain this is a hardware issue.
When connecting USB-C to USB-C with my laptop, the phone will start charging but will not register that it is connected to a computer unless USB debugging is enabled. Even then, with debugging enabled I will usually, but not always get the option to switch from charging mode to MTP/file transfer mode, but when I try to switch the phone will just disconnect and reconnect several times and revert back to charging mode. It has only every actually established a data transfer connection 3 times out of probably near 50 attempts over the past week.
I have tried two different type-C to type-C cables, doesn't make a difference.
I had the pixel 1, and had no issues at all with the same connection and with either cable, so I can safely rule out the cables or the laptop as the problem.
The issue was present with 8.0 firmware and is still present with 8.1 beta.
I did try booting into safe-mode, and the problem was still present.
I did a full factory reset, and the problem still persists.
This issue is specific for type-C to type-C, when I use a USB-C to USB-A cable, the phone will immediately recognize a data connection and allow me to switch from charging mode to MTP/File transfer mode, regardless of whether USB debugging is enabled or not. Though the phone does occasionally hiccup and disconnect/reconnect itself so it may take a second or third attempt at switching to MTP mode, but then it will establish a steady connection where I can access the phone's data.
I just got off the phone with google support, the rep mentioned he has heard of a few instances of a similar issue, and since I've already exhausted all possible troubleshooting they would have recommended, they are sending me a replacement.
I've been a loyal google customer since the Nexus 6P. It's a shame the LG's quality control was so shoddy with this product, now I have to wait and see if the replacement doesn't have the same issue or if it ends up having worse blue screen shift than the phone I am replacing.
At least I can say that google's customer support is on point, kudos to them for trying to make this right.
Alright well I may try this. IDK if it's worth an RMA tho, my a to c cable works fine, I just more or less can't charge off of it because it's too slow

Might not be worth RMA to you, but considering that it's a brand new $1,000 device (XL 128GB) I'd want to make sure I had one that doesn't that doesn't come with (more) problems out the gate... and since type C is the new standard, eventually replacing type A, and google is promising 3 years of updates, I'd like to ensure mine is future proofed as I intend to keep mine for a while.
I have the same issue and apparently so do lots of others. Did all the norm right off the bat, usb debugging on, tried every usb port, toggled PTP, MTP, etc. (currently left on MTP). An option pops up to choose either "transfer files" or "charging". It will never leave "charging" mode. The radio button will not select transfer files. Super annoying that a 1k phone has ridiculous hiccups for such basic hardware components.
Has anyone fixed this issue? I have the exact same one. My OG Pixel on Oreo worked fine on my motherboards USB c port. The Pixel 2 does not work at all. I can use any USB a port and it works... This is funky

Stuck with the super slow A to C cable
Last week I wanted to plug in my phone into our shop's stereo, using the the official included USB-C to 1/8th headphone adapter. I plug in the phone, fire up my music, but the audio continues out of the phone's speakers.
So I unplug and replug in the adapter, and the aux cable a couple of times with no luck, even restarted the phone to see if that would do it.
At that point I thought that somehow the adapter was damaged, so I ordered a replacement (making sure to get one with a DAC [sidenote: **** any manufacturer that makes you not only have to get an adapter for headphones, but makes you have to get a SPECIAL adapter])
No dice with the new adapter.
I went a couple of days not really worrying about it, the phone charges just fine, like it always has, so I didn't think it was a hardware issue. I thought it was just bad luck with these stupid, terrible, superfluous, awful adapters.
But today I had to pull a file off the phone to my computer, using multiple known good Type-C to USB-A 3.0 cables.
Phone says it's charging, but I didn't get the notification to select USB mode, and USB ADB debugging never showed up.
Windows is constantly making the device connected, disconnected sounds, and device manager is showing me an "Unknown USB Device (Port Reset Failed)"
Is it possible that somehow the data connections on the port on the phone are damaged, without it affecting power delivery? I have no idea how that would work, Like I said, it charges just fine, and all my cables feel pretty secure when plugged in, there's no play or wobble and I don't know what to do to troubleshoot it further.
You can try to clean the port
I have the same issue. Ive requested a replacement aux dongle from Google and still no go. It charges fine, connects to my computer fine adb, data transfer etc all work, only for music it continues to play from the speaker even when connected.
Yes it's possible for the phone to get power but have no data connection it's happend to my Nexus 6p I paid for the insurance so I had to pay the deductible to replace I have had some data issues with the pixel 2 xl but always seems to come back after a few days could just be a dirty connection since I work construction and some times gets very dirty.
But I'd be careful of what cables you buy when they are usb a to c but seem to have no issues with c to c
I have the same problem and are trying to work with Google for a fix. I have tried everything and they are pretty useless. I am now requesting a new device as I'm still under warranty.
I just bought a used Pixel 2 XL and it has the file transfer/ADB/fastboot over USB problem. I've been through every solution here and on Google Pixel support with no luck (see below).
The phone connects via USB for a second and brings up ADB debugging auth, then disconnects. Every other thing I plug into the phone works fine (thumb drive, OTG camera, charger). Wireless ADB works fine, but I can't unlock the bootloader this way (that I know of). I can't get ADB or Fastboot access in bootloader or recovery mode.
I'm guessing software/kernel problem on the phone since everything else works with the USB port. I'm currently running build RP1A.201005.004.
On the factory image page, there's a new image, RP1A.201005.004.A1, Dec 2020, that I hope is a fix, but I've got no way to install it except if I get it OTA.
If anyone has any ideas on other things to try, please LMK! Thanks!
Solutions I've tried:
Cleaned port, dozens of cables, USB 1, 2, & 3 ports on four different machines and three different OS that work with ADB on other phones, every phone ADB/USB setting on/off in all combinations, cleared data for external storage, can't clear data for media storage because it's now grayed out in this build.
I've also tried the old tricks to try and get the OTA sent, but I'm guessing those tricks don't work with Android 11.
I may try replacing the internal USB port and cable since it's only $7, but I don't think it's the problem from what I've read in other posts here.

I just installed the update using ADB from my Chromebook via Crostini Linux. I had an issue at first due to the USB cable I was using. Switched to a USB 3 cable and it worked flawlessly. Kinda weird that after the update it still says October 2020. Looks like the .A1 on the end of the build is the only difference, other than whatever security updates they pushed.

I just got the update OTA today. I still can't get a USB connection to work for longer than a second or two. I've tried dozens of cables and several computers. I'm going a little crazy here.

I have noticed mine is a little finicky with ADB, especially when connected via USB 3.0. Connecting with USB 2.0 with a good cable seems to always be reliable and never disconnect. Also if you haven't tried using the stock cable that came with the Pixel, I would try that for sure.
I just replaced the internal USB assembly and nothing has changed. The old connector was definitely worn though.
I'll go back to trying more cables and ports. I ordered a cable that another poster claimed worked for them, but I had no luck with it.
For anyone wanting to replace their USB ass'y, here's what I learned from doing it. The service manual on ifixit is a good guide but leaves out a couple of important steps.
Heat is your friend. I used a clothes iron adjusted to 160F. The phone dissipates heat quickly so you may need to heat it several times. Place a towel over the screen and set the iron on it. I used guitar picks to pry up the screen and keep it separated while I heated the other sides.
The screen cable connection covers are hard to remove and you'll probably need a to use a metal spudger.
Heat the back of the phone to help remove the loudspeaker ass'y without damaging it, and again to remove the old cable ass'y.
The replacement ass'y I got had adhesive applied for the center of the cable, but not the adhesive foam pad under the antenna connector, so heat and scrape between the pad and phone body to remove it intact for reuse.
My old antenna connector partially came off in the white antenna connector and it was very hard to see what was wrong even under strong magnification.
You'll need a new screen adhesive sheet to reattach the screen securely.
Both parts came from a seller on ebay. Dougsgadgets was the only one that had both parts in stock. I think I paid $11 and they shipped quickly.
Good luck!
