Computers not recognizing (rooted) phone - Google Pixel 3a XL Questions & Answers

I've updated all drivers on different computers, tried with different cables, turned on and off USB debugging, and switched phone to File Transfer and other settings, revoked usb permissions, etc, tried to connect while in fastboot, etc. My guess is the issue is something in the phone itself. I also have not received (phone doesn't see them) updates since January, which is the firmware I'm on. Anyone else have ideas on how to get the phone to talk to a computer? Thanks all.

I would download March... April if it's posted full image and see if you can fastboot the new image to the phone. Use the flash-all.bat or .sh if your Linux that comes with the download.
BEWARE this will erase all your data unless you change a line in the a flash-all file.
If your not perfectly clear on what i am suggesting post back... do not try this unless you understand completely what i am recommending.

Help!! USB connection not recognized...

I connected my SG2 via USB cable to my PC and started seeing this error
"One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it. For assistance in solving this problem, click this message."
I have tried everything from changing cables/PCs/enabling/disabling USB debugging to *#7284#, and none of them work ...
Is the device bricked, is there any hope of revival..please help i got this phone myself paying $400
Does your phone turn on and work and a connection to PC the only problem? If so your not bricked...you prolly need to install the drivers in order for your PC to recognize it so install kies on your PC

Yes phone turns on, charges through the port...just that it is not recognized by the PC....what could be wrong?
As I said previously you probably need to add the drivers on your PC install kies on your PC

Make sure you use one of your rear usb ports also. I had an issue with drivers installing in a front usb port.
Phew it turns out to be the samsung driver..I believe kies update must have corrupted and stopped the pc from recognizing the phone....

The definition of "bricked" is having a really expensive
... brick. It means your phone doesn't turn on no matter what you do to it (short of a JIG and that's not guaranteed) the "USB device not recognized thing" is a problem w many windows devices my vista computer does it all the time and I just switch ports.

Having same/similar issue
Hey, was there every a solution found for this?
I'm having basically the same problem...using the cable that came with my phone, and have installed Kies (fresh). I have tried toggling multiple settings. I tried uninstalling kies and reinstalling. I tried using pdanet for the driver. I have tried a few different roms, as well: Darkside 2.4, 2.5.1, and gingersnap 1.21. All have had the same result.
When I plug the phone in, it beeps (charging) but no notification for usb settings (disk drive, sync, etc). On my computer, it pops up "USB Device Not Recognized" and says the device has malfunctioned, etc, same as OP.
In Device Manager, it shows under USB as "Unknown Device".
I have tried this with two Windows 7 laptops, and a Windows Server 2008 R2 desktop. Also tried with a different cable. This cable was able to transfer data from an external hard drive today, so I doubt anything is wrong with it.
Any help is greatly appreciated!

Did you try the drivers separate first or Mtp mode
Sent from my revolutionized Samsung infuse
I tried without the drivers, and went to wireless and network > USB utilities. The only option in there, however, is "Connect storage to PC". If I try that, then plug it in, the phone acts like I hit the back/undo button. It doesn't show that anything is connected, nor does it give any other options. At this point on the computer, I get the "USB device not recognized" error.
This happened before installing Kies/Drivers, and still happens after installing drivers and kies.
try another usb cable
i had the exact same error, and it ended up being a good USB cable that went south
I will try a different cable when I get home - Have a month old cable for a mytouch 4g that I know works.
Okay, I tried it with the other cable, on a desktop in the rear port. same thing...Phone start to charge, and I get the error that the device malfunctioned, yada yada.
Any other ideas? Should I try to connect in Download mode?
Alrighty, so in the end, I ended up completely unroting, using terminal emulator to remove superuser.apk, busybox, and su and putting right back to read only. Then in CWM, flashed a stock 2.3.5 ROM (Zedomax). However, I now have the 2.3.5 ROM and the 2.3.6 KL1 Kernel...
I'm planning to return to Tmobile/Samsung - will the kernel and rom versions not matching be a huge red flag??
Any help is appreciated. I have tried to flash the 2.3.5 kernel, but I always get an error that it's not signed/verified.
Ideas?
I was hoping to grab the 2.3.6 OTA update, but it says there is no firmware update. Is there an update file I can put on the SD card and update using the stock recovery?
UPDATE:
I called T-Mobile Customer Service today, and went through the "troubleshooting" with them again. They ended up sending me a new one, overnight. They didn't ask anything about doing anything custom with it like rooting or other modifications.
I'm not sure if it made a difference, but I'm within 90 days, and also have the "best" insurance/warranty coverage through T-Mobile, and whoever their insurance provider is that I signed up for when I bought the phone.
Final charge is for $5, which I was told is some kind of fee from Samsung, but will appear on my bill.
Anyway, not too bad. Can't wait to get rid of touchwiz again when I get the new phone!

FYI, I just went through the same thing. Decided to finally root my phone after owning it for 2 weeks.
Phone nor the phone would recognize USB data, but would charge. Tried another cable and no luck.
Rebooted the phone. Works like a charm now.

[Q] USB not connecting to computer

So I can't get my s3 to connect to a computer. I have tried three different computers, two windows and one mac.I have also tried three different usb cords including the one that came with the phone and a brand new one I bought just to see if it was the cord. Have done a factory reset and tried everything with usb debugging on and off. My phone will charge but the computer doesn't recognize it. I have reinstalled the drivers twice on both windows computers and tried the Kies troubleshooting. I have also put it into download mode and Odin doesn't recognize it. When I plug it into the computer nothing happens, no sounds or messages saying something was plugged in. The phone does not have the option in the notification menu for usb debugging. I can use AirDroid to put just about anything I want to on my phone over wifi so I am not too upset about it not connecting but I would really like to put CM10 on it so I kind of need it to connect. I am using the stock AT&T rom. I rooted the phone awhile ago but then wanted to update so I went back to the stock rom and then updated. It would still connect to the computer after this update. Unfortunately I did not reset the flash counter so I doubt AT&T will do anything about it when it shows I have messed with it. I kind of think it is a hardware issue on the phone after doing all of this. Does anyone have any other ideas on what I could try?

[Q] USB Device Not Recognized & No Previous Solution Working (Win7)

I'm trying to root my Samsung Galaxy SIII, and whenever I try to connect it to my laptop, it gives me the "USB device not recognized" error. I have tried everything I can think of.
Kies uninstalled, registry cleaned, searched my computer to erase every file linked to Kies, and no dice.
Installed, uninstalled, reinstalled, re-uninstalled, re-reinstalled drivers. Nothing.
After every driver change, rebooted computer and phone, nothing.
Factory reset the phone since one post I found had that work, still nothing.
So right now I have a laptop with no Kies, Samsung drivers installed, a factory reset phone, and the USB cable still won't work. It is the cable that came with the phone. The phone is Android 4.1.1, an SGH-I747, build number JRO03L. This is extremely agitating since I can't even connect my phone to see the files on it! I had a Motorola Atrix and had a similar problem, but fixed it with a simple driver reinstall. I've even gone into the hidden code menu and set the USB mode to MTP+ADB, and the UDAP (or whatever) is set to PDA. That won't even work. At this point, I'm willing to do anything. I hate stock ROMs, and want to remove all the crap this phone has on it, especially that damn voice thing and Kies.
self bump, since it's been three or four days with no reply. I could really use advice on this.
In your laptop, when you go to Devices manager, do you see an unknown device? If you try searching online for the appropriate driver through Windows Update, does it find any helpful driver?

I was dealing with this on my Win7 rig, and came across some advice that helped. If you have an SD card installed, turn the phone off, remove it and then reboot and connect the phone to the computer. I don't know why it worked for me, but it did.
Good luck to you.

Possibly two things download revouninstall to uninstall your drivers it searchs bolth registry and system for left over files (delete them)
I had same problem all I did was use revouninstaller to uninstall old drivers (it scans entire system and registry for left overs. a must.
Then I used these drivers, also when letting your installing drivers (turn internet off) don'lt update them there older, but they work for everyone who does this. If you need a better guide search there is one somewhere but point is use these drivers and don't update them (smile) works with adb everything you won't see a difference these drivers work better. peace.
Drivers------>Samsung Drivers 1.4.6.0 search for 1.4.6.0 drivers samsung fix for more info later
search for revo uninstaller
Whenever I have this problem, I must manually install the driver.
Open device manager.
Go to the unrecognized device that you know is your phone.
Properties and "update driver".
Tell it you have your own driver.
Don't let it "search" for a driver.
Manually point it to the exact driver file you need.
Works every time for me.
I took out the SD card to try all possible solutions posted.
Uninstalled drivers and installed the older versions that one of you linked me to, didn't help.
Tried directing Device Manager to install the driver manually, but I have no idea where to find it. If you have the driver file or at least the name and version, I can get it and use that.
I can't believe how much trouble it is just to hook an android phone to a computer, this happened with my Atrix as well.
Have you tried and different cable ?
So I was having a problem with my laptop recognizing my S3 when connected via USB. The notification would not appear in the status bar that a connection was made, and neither Fedora Linux or Windows 7 would recognize that the device was connected. I tried reinstalling Kies/drivers under Windows, and checking the output of dmesg/lsub on Linux. Nothing.
Did some googling and found this thread that help solve the problem!
http://blog.vacs.fr/index.php?post/...ot-detected-problem-on-Android-Samsung-phones
I found the problem. It was the cable. Somehow, it was severed where the cable connects to the mini-USB connector. I discovered this when the entire mini-USB piece fractured and fell off, revealing the tangled and snapped wires. I went today to AT&T to buy a replacement, and it worked on the first try. I don't know how the cable got damaged like that without being detected, but there we go. Now how do I set a question as resolved?

Phone not Mounting on PC

So my phone was mounting fine on my pc, and then all of a sudden it wasn't. My Nexus 7 still mounts properly and accepts developer commands, but the m8 won't (yes developer settings is on).
I tried wiping and flashing a rom clean and it still doesn't work, charges fine though. Any advice?

I'm having the same issue. Stock non rooted and it will not connect. I have tried it on other computers cables ports everything.

You might try a different cord.
Open Device Manager in Windows and then plug the phone in. Do you see it in the list with a little yellow triangle? Do you see Android USB Devices listed?
OP after literally messing with various driver files, 8 usb ports and 2 laptops, I dug out my old box of cables and found a taped up, on its last limb OEM HTC EVO 4g (not lte the original) cable. This thing has been through the ringer. But its exactly what It needed. I figured with the 3 cable I had already tried this wasn't the issue, but have you tried using an OEM cable? I guess that is all that works. Good Luck

Uninstall all HTC drivers and HTC Sync. Then connect the phone. DO NOT choose the option to automatically install any drivers.
Open Device Manager, find the phone. Select the option to manually pick the driver, and select the generic MTP device driver.
This is what worked for me, after countless attempts at re-installing various HTC drivers, different cables and ports, etc.
Bump. Still looking for answer to this. I have RUU'ed both to Sense and Google Phone editions and the problem still persists, the phone does not detect its connected to a computer and change to mtp accordingly. Only way I was able to get the RUU in there was through fastboot, which is again the only time I can access the phone through usb. Adb is no luck in either android or recovery.

Have you tried revoking the USB debugging authorization and then accepting the RSA fingerprint key again when connecting to PC?
Obviously it can't be an USB cable problem if you can connect to it in bootloader mode and use fastboot commands.
To clarify, the phone just charges when connected, it does not detect that it is connected to PC so debugging doesn't even trigger, neither does mtp. I don't even get the slow charging notification
Does it do the same when you plug it in and reboot the computer to "pick up" during boot up process? Or if you run a live CD? I never had an issue like that with my phone but I did have a similar problem with the USB external blu ray drive I bought some time ago. The pc just didn't detect it at all not on any of the ports until I rebooted my PC with the drive already plugged it and for some reason it picked it up. <Not a solution as I don't know what caused it to not be detected in the first place but still...
Not sure if it's an issue with the device(Phone for you, blu ray drive for me) or if it's a problem with the PC even though other things might still work for you as it definitely did for me(phone, headset, mouse, keyboard, usb extender + all the external hard-drives connected to it)...
Problem exists in all computers, Mac, pc, linux
Did you try what I suggest in Post #6 above?
This worked for me when I had the same issue. adb and fastboot would work, but it would not mount MTP.
And just in the last day or 2 I helped someone else with the same issue and fix.
The phone doesn't show up in device manager.
Have you modify the Kernel? (Applying some settings for example)
I browsed over the web for this issue and found some people with the same problems. They solved by removing the settings applied on the kernel or flashing a new one.
I've flashed various kernels and ruu, still same result

pixel 2 xl refuses data connection with all computers except one.

Hi so i installed twrp and rooted my pixel with magisk. everything went fine.
saw the sultan kernel decided to flash but my phone does not recognize any computer with any cable as a computer but as a powersource. Adb and fastboot not working on any laptop or desktop (except the desktop on which i unlocked my bootloader and rooted my device) tried to connect over usb (adb fastboot filetransfer) on Linux Windows and MacOs. all unsuccesfull.
dev options is on:
oem unlock toggled
usb debug toggled
phone is running stock rom stock kernel. (Edit: kernel is the sultan kernel on stock rom)
once i connect the phone sees it as a pc pops op usb options then blacks it out because it sees it as a powersource.
whats wrong with it i cant figure it out...

I'm in very much the same situation. I've seen several USB connectivity threads roll through here recently so I'm not sure if anything larger is going on or not. Basically, I always do updates with full factory images w/o wiping. I was able to install the April update (in early April) just fine. I went back in late April to try to use fastboot and couldn't connect via USB for file transfer, ADB, or fastboot. I updated all my platform tools and the Google USB driver which made no difference. I tried on 3-4 Windows 10 desktops/laptops and 1 MacOS laptop. Nothing. I opened a support ticket with Google (and went through extensive troubleshooting steps) which was then escalated. It has been over a week and they have not responded. I even checked back yesterday to make sure it wasn't lost in the shuffle, and I was assured that it was still active and assigned to the proper team.
Just for giggles, I tried connecting to a Win7 desktop w/ only USB 2.0 and the phone immediately connected MTP (we had made this the default USB mode during the troubleshooting process). Since I was still running a modified (root) kernel, I went ahead and tried flashing the stock boot image with fastboot (both slots) and it worked! I figured since I had already wiped the phone for troubleshooting, I would try pushing the entire April image (w/ wipe). It flashed bootloader, radio, and maybe boot image (can't remember), but then lost connectivity when trying to push the system image. Fortunately, the phone booted right back up. Since then, connectivity is possible, but sporadic, on that machine. Being 100% stock, with no other options, I knew the only way to get an entire factory OTA pushed to the phone would be to opt into the beta, install the beta, then opt out, which pushes the latest non-beta and wipes the phone. I did this, but, again, it resolved nothing.
BTW, for me, this issue affects all devices that pass data through the port including USB OTG flash drives and game controllers. It's also not cable specific as I have tried a factory Google USB-A to C cable, factory Google USB-C to C, and several other USB-A to C cables (the ones I always use for ADB and fastboot commands). There does not appear to be any physical damage to the port and I cleaned it extensively with compressed air and a plastic dental pick.
Sorry I don't have a solution at this point, but I wanted to pass on the steps that I have taken.
