[Q] PC won't even acknowledge that a device is connected via USB when M8 is connected - One (M8) Q&A, Help & Troubleshooting

I've had my One M8 for about 6 months and had no issues, until now. The phone is unrooted, and has never been altered in such a way.
About a week ago I noticed that when I connected my phone to the USB charger plug socket that it said "Slow Charging" in the status bar, however other than that everything seemed to be fine.
However, today I've connected the USB cable to my PC in order to copy some data, however the phone simply states that it's "slow charging" and does not recognise that it is connected to a PC. The PC does not show anything in device manager (not even an unknown device), and I have tried using multiple different drivers, USB cables, and even a completely different PC (a windows 7 one vs my windows 8.1 pc).
Whatever I've tried I cannot get the PC to even acknowledge that a device has been connected, even after twice factory resetting the phone.
Any ideas how I can get a PC to even recognise that there is something connected?
Thanks

Install HTC Sync. Run it to get the drivers, then uninstall HTC Sync.

Also try to give an update
when/if you fix it and what you did so those that view your thread can learn

USB connection not working.

My TP2 (vodafone) has decided it doesn't want to connect via USB any more. I have tried different USB leads, and verified it's not that by using other devices. I've tried different USB ports on my desktop (Windows 7 RC 7100) and also tried my laptop (XP) neither of which want to connect.
I've checked the USB to PC section in settings and tried it as both Activesync and disk drive, and with and without the 'enable faster data synchronization' box ticked, and soft reset after changing each setting. but every time the computer just won't recognise that I have plugged a USB device in.
Any suggestions?
No one have any ideas on this? I've tried a hard reset now in desperation, and it still doesn't seem to work.
PC does not recognize TP2 connection
Same problem for me; the TP2 is not recognized by the PC (or laptop)
Is there no program to check this? Otherwise.......I have to send for warranty repair.
Anybody any idea??
I have the same problem.
I can't get the device to connect to my PC by USB. It charges through the PC USB lead though.
What did you end up doing? Is it time to make a warranty claim?
I'm not sure if it applies to your situation, but for the longest time I could not get my Kaiser to sync with my laptop (which I usually kept wifi off on).
Turns out ActiveSync was out of date and didn't work since I had upgraded to WM6.1. If you're up to date already that probably doesn't help, but I thought I'd toss it out there.
just to let you know, i returned my tp2 to vodafone and the replaced it. the new one worked fine as soon as i plugged it in to the usb. so that proved it had to be a hardware fault.

ATT Tilt 2 won't recognize computers all of a sudden

I have an ATT Tilt 2, and I've gone through roms like candy, and I still use the original USB cord that it had came with phone.
So I just bought a new computer a week ago, and ever since I can't seem to sync my phone up to my computer via usb cord (Bluetooth works fine). Now normally there's the steps to find the drivers, make sure active sync is enabled, make sure that small checkbox is checked or not. Data connection is enabled/disabled. Prompt when its connected to the comp, etcetc.
The problem is, the phone doesn't recognize that it's plugged into the computer, and just treats it as a power source. I've done some reading, and found there's a program that lets you trick it into thinking USB ports are power sources (fast charge or whatever) but I haven't downloaded nor install it.
Currently I'm running an EnergyRom rom, and I can't update it or change it.
I used to upgrade the rom every time NRG came out with an update, so I'm baffled to why all of a sudden it won't work.
Edit: I've tried connecting it to several computers, does the same thing. It won't realize it's connected to a computer.
Usually, if I pop out the battery, hit the power button a few times, then start it back, up... it will go back to working. The only times I ever seem to have this problem you are describing though is when I switch from active sync to "usb" (where it only looks at the storage card) and then when I switch back to active sync next time I plug it into a PC, it will not connect.
you should try to reinstall the activesync if you use xp.. hope itd help..
regards..

HTC M9 Connecting to Computer Problem

Hey Guys,
First of all, I am a new member here my name is Salem and its an amazing forum.
Anyway, I have a slight problem with my HTC M9 while connecting it into my laptop. First, when I connect it, the mobile starts charging, and it gives me no option as to change it to Media Transfer or anything... even it gives me "Slow Charging" Error, and my laptop is detecting nothing, as if nothing happened, nor its searching for any drivers...
I went to developer menu and used USB Debugging, and selected USB configuration as MTP, and it didn't work...
I installed HTC Sync to get the drivers, and it is the same.
Can you guys help me? because I wanna root the phone and I tried various Auto Root applications without using the PC and they didn't work. Thank you guys
No signal from the laptop probably means you have a faulty USB cable. Most likely a break in one of the data wires.
Try another good quality usb 2.0 cable.

Same issue. Tried multiple cables
I have the same issue. When I try to plug into any PC a slow charging message pops up but the phone won't give me the option to connect to PC. I have turned on USB Debugging and selected MTP (Media Transfer Protocol). Please help!
I am with TPG. Android 6.0 HTS 7.0 Software number 3.35.617.12
I only bought this phone a week ago and it updated when I turned it on.

Most likely a crap or broken cable. Other cables, other sockets, other pc's are all worth a try.
You should leave the usb port in "charging only". When you successfully connect to a pc the phone will prompt you to allow data transfers to that computer.
I know this because mine does it. I'm sick to death of the effing thing promting me to connect to my xbox one when all i want to do is charge the effing thing... My phone is set to charging only.
I suppose rom choice will affect it too. Mine is rooted stock 6.0.

Still have same problem
I still can't connect my M9 to my PC. Still have slow charge message come up and no option to connect to PC. My work around has been transferring files using WiFi. However, now I need to do a presentation using scrcpy and will probably have to get a new phone. I'm tmepted not to buy HTC again. Pretty frustrating and no fix found on the internet...

Connecting to PC - not recognised on Win10

Had my A70 since July time, no issues so far, except for now. First time I needed to connect to my PC, Win 10 comes up with the 'WIndows didn't recognise the device' error. Have tried 2 different USB cables thinking it might be that but no different. Then I plugged my partners identical phone into the PC and it recognised it straight away so am assuming that there's no issue with the PC itself in terms of drivers etc. USB configuration/connections settings on both phones are identical, i. e. 'Transferrring files'. Tried Developer options with USB debugging on, I get connection sounds but eventually the error message on the PC. Anyone had similar or any ideas what the issue with my phone might be because i'm stumped?
OK, sussed it. With phone connected to PC I turned it OFF. Then turned it on again still connected. PC recognised something as an ADB device and said I needed to restart the PC, which I did. On restart, Device manager showed a Samsung Mobile USB Composite device connected but still didn't show in Windows Explorer. I disconnected the phone from PC and then plugged it back in again, this time I got a message on the phone asking me if I wanted to allow connections, I pressed 'Allow' and there it was.
Didn't have to do this with my partners phone so have no idea why mine should be any different!

Google Pixel XL doesn't show up in Windows Device Manager when I connect it via USB

I just purchased a mint condition Pixel 1 XL on ebay. It arrived with Android 9. I should have plugged it in then to check if USB file transfer mode would work. But I just assumed it would since I've never had a problem with any device in the past: various apple phones, samsung tablet, google nexus tablet.
So I updated the phone to Android 10 before I plugged the phone in, and then discovered it refuses to recognize my device for file transfer, only for charging. It does not show up in device manager at all, even though it is charging. The phone makes a sound to indicate it is charging, but it does not pop up with anything to ask if I want to connect to the PC. The phone 100% acts like I just plugged it into the wall instead of a PC.
OEM unlock is enabled.
USB debugging is enabled.
Default USB configuration is set to File Transfer mode.
I already installed the latest android_winusb driver.
I've rebooted both the phone and the PC.
I've tried plugging it into 3 different Windows 10 PCs with google android usb driver installed. Only one of those PCs has samsung android drivers installed on it. The others only ever had iphone plugged into them. So there shouldn't be any drivers interfering that I know of.
But no matter what, it only charges the device, it never recognizes it in device manager.
Since I bought this off ebay, it did not come with the official, original USB cable.
I'm praying maybe it's just the third-party USB cable causing the problem. But I can't find any cable that is verified to work for File Transfer. Do you know where I can buy a cable like this? Link please?
If it's not the cable, is there any way out of this situation? If I can't get device manager to recognize the phone, I think it's impossible to flash the phone back to Android 9 or something to see if Android 10 broke something???
I've already read some really scary posts online of other pixel phones of various models simply stop recognizing their phones in device manager and they never get it back. It becomes a fancy brick that works as a phone, but you can't actually do anything with it because no PC will recognize it.
I was excited to try a pixel phone for the first time until this happened. What the heck, Google?
Ok I think the stupid trick is you have to UNLOCK the phone BEFORE you plug it in. If you plug it in, and then unlock it, it will never give you a notification asking to connect to the PC no matter what you do.
As someone used to iphones, at least iphone says "unlock me" when I plug it in and it doesn't properly connect. But plenty of other times it will connect to device manager even if I don't unlock it.
Kinda annoyed Android doesn't say anything at all when you plug it in without unlocking it first.
