[Q] No USB connection to the PC - Galaxy Ace II Q&A, Help & Troubleshooting

Due to the certain amount of posts I must have to ask this question here I'm asking it in this subforum.
Basically I can't connect my Ace 2 to PC. I'm currently on 4.4.3 from slv96, and first time I plugged my device to PC it was fine. So I got it out, played a little and now I'm stuck because when I connect my phone to the cable it's charging but there's no info or data whatsoever on the computer. I've tried this on-off debugging mode but with no succes. I've also tried to connect my Ace 2 to Acer A500 Tablet. A500 can't display the content on my phone (no biggie) but there was a sign on both devices that the Ace 2 is plugged, which is absent on the PC.
So that's what's up. If anyone could help me with this issue - that would be great.

Unable to connect to USB, after update?

Hello guys, I hope I can get some help over here.
When I received my galaxy tab pro 12.2, my galaxy tab pro 12.2 can't be connected to any usb device nor the pc's usb port. The last time I remember I plugged my tablet to the pc and transfered files to it was like 1 and a half months ago, then I updated my tablet, then last week (I had no need to connect my tablet to my pc until last week) I needed to transfer some files to my tablet but it didn't work, I don't get the typical sound Windows makes when you plug in a device, it doesn't appear on the device manager, I tried it on 3 different laptops and it still didnt work, on my tablet I only get a red cross on the battery sign at the top right of the screen, I tried to connect it also with an mlh adapter to the TV, and no success so far.
Has anybody else had that problem?

[Q] PC won't even acknowledge that a device is connected via USB when M8 is connected

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

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...

PC does not recongnize the Tablet

since more than 6 months the PC or Laptop doesn't recognize the P605, I tried to change the microusb port, tried different USB ports, PCs with no luck.
When I'm connecting the tablet to PC the tablet will charge but nothing appear in the device manager, no detection at all.
appreciate your help guys solving it, I bought Tab S3 but I still like the old fellow more
No detection, so the thing's completely inert when plugged in?
When I plugged in my Note to my 3.0 USB laptop, out comes 'Device not recognised' in the taskbar, and that's it. However, it all works well when I plug it to a computer with USB 2.0 running XP/7. A brief search shows something about incompatible default/microsoft's driver with old(er) devices on USB 3.0.
As you've mentioned several attempts above including a hardware change, I believe the problem lies with software somewhere.
I have the same problem and get an "error 43" message. My Note 5 works fine when plugged in. I must have damaged the port upon changing the battery. I wanted to upgrade to 6.0 but looks like I'm out of luck....unless I can update via update.zip on my P600
