I have a P769 Tmobile running V20H
When I plug into a USB 2.0 port, the phone trickle charges, usb connects, etc, everything is fine. When I plug into one of my USB 3.0 ports however the phone just charges and doesn't connect. I want to be able to connect to a USB 3.0 port. I remember it did once, but I believe that was on an older ROM. Other phones connect to the USB 3.0 perfectly fine, so I don't think it's the PC's problem.
Does anyone know the solution to this?

when I connect the USB cable onto the computer the USB notification fails to appear and the charge indicator doesnt work. The USB cable works as I had just unlocked the bootloader but now the USB does not work and I cannot charge!
Anyone ever come across this problem? RSD still detects though so I guess there may be hope
Most usb cables work to charge my phone, but won't form a data connection with my xt910. I do have one that will. I thought it might be the cables, but they form a connection with other devices.
What is going on????
Also, I just got the usb port replaced thinking this was the issue...
edit: Thought I'd mention, it says a usb is connected regardless of which cable I use in ap fastboot.
So I got 3 USB-C to USB 3.0 cables from Anker. After a lot of trying, I figured out that they would not work for transfering files to my PC with the MTP protocoll. The device would come up in Device Manager as Code 10: Could not start device or something like that.
After contacting the support, they send me 3 new ones but they have the same problem. So I assume that it is a problem with the cables because with the stock LG cable everything works.
Does anyone have had similar problems? Does anyone have a third party USB cable that works with MTP? Could it be a problem because it is USB 3.0 and not 3.1? Any hints?

On certain machines I had that happen when I used a usb 3.x cable on a 3.x port but worked when plugged to usb 2.0 port... meanwhile would work on usb 3.x port on my laptops. Did further testing and found that usb 2.x cables would work on usb 3.x ports on the machine that couldn't use usb 3.x cables on 3.x ports. One thought also was that the problem machine has lg bridge installed so could be issue with the lg drivers while its fine on the generic mtp drivers.
So as a test try using those cables on any usb 2.0 ports on your machine and if that works i guess that's a workaround.
I face the same problem. My cable is Anker PowerLine+ USB-C to USB-A 3.0 and MTP doesn't work when plugged on a 3.0 USB port.. PTP works but there is no diffrence and it's limited to functions.
I'm using Anker Powerlines, are you sure it's not a driver issue?
What drivers are you using? The ones from lg?
Try the ports in the back of your computer, i switched it and it worked for me
I had a similar problem, but there is a newer LG USB Driver (4.2.0).
I would suggest removing the older driver (probably 4.1.1) and then installing the 4.2.0 driver:

I am now using the G5 with this Anker PowerLine+ USB 3.0 Type C to A cable without any problem.

It say unknown device when i plug the device in
What i tried:
- Reinstall adb and lg driver, try 3 version of lg driver (4.5, 4.1, 4.4), pretty sure i work fine because i can connect with my G7
- Try plug in another port, and i notice if i plug it to my USB Root Hub (3.0), it not get recognized, but if i plug it to a Generic USB 2.0 Hub, nothing happened, it only charging (no error appear and no device appear) - I used usbtreeview to see it
- Tried with different cable, and i bought new 2.0 cable, but it still not work
- Tried buy a 2.0 USB Hub, but it get the same error as i say above, the device just charging, nothing happen, no sound of new device plug or anything appear in device manager
- Tried change the mode of usb config to MTP, PTP , then connect each mode with usb 2.0, usb 3.0 port, same problems
your V30's usb port might be going bad.
try and see if cleaning it with a wooden toothpick helps. Don't use anything metallic or conducting

I will try it! Also do you know why it throw error at when connect to usb 3.0 port of pc but nothing happen with usb 2.0 port ? (just charging),
also when try some cord, i notice that if i use my lg g7 cable and samsung cordand charge directly, it not even charge, but if i use that cord and plug to pc, it does charge ._. , and if i use my oneplus 8 cord, it work for both charge directly and plug to pc, which is really weird since all of them is usb 2.0 cord i think
Yesterday I had my Mi 11 Lite delivered. After setting up the SIM card and so on, I tried to connect it to my Windows PC to copy the photographs that didn't migrate during the device transfer procedure.
Plugged it into the PC, it failed to appear in file manager. It started to charge, but wouldn't connect otherwise. Tried all the usual of setting the default USB, turning on USB debugging, nothing. Tried various different USB sockets, USB hub, nothing. Getting very frustrated, I was thinking I would return it for a refund. By this time it had downloaded an update and requested a restart. As it restarted, it was plugged into a USB port and once I unlocked it, hurrah! It connected. I then copied over the pictures. Happy days.
A little later I re-connected it to the PC and again, nothing. I installed the Xiaomi connection suite and it complained that there was no device connected. Eventually I installed Smartisan's wonderful Handshaker which creates a WiFi connection and copied over some files using it. I was still annoyed though. This morning I thought I would try connecting using my Laptop. No connection there either. I tried a USB OTG flash drive, it wouldn't work. Thinking I really would have to return the 'phone, I rebooted it. When it restarted, I plugged the USB OTG drive in and this time it appeared. Plugged the 'phone into the PC, nothing. Plugged the OTG drive back in, nothing again. Rebooted it once more, USB OTG worked. Thinking I was starting to go crazy, a thought suddenly struck me.
When I had plugged it into the PC the very first time, I had plugged it into a USB-C port on the PC. When it restarted, it was plugged into a USB-A socket as that was the last port I had tried. As the USB-A port had worked, I had then tried the USB-C port, which didn't work and after that nothing connected to the 'phone worked.
My PC is a Lenovo all in one which should allow use of the screen and keyboard to be shared with a mobile device when plugged into the PC's USB-C port. My guess is that the PC is trying to connect to the Mi 11 Lite, offering to share the screen and keyboard which then confuses the 'phone and blocks all access to the USB on the 'phone until it is rebooted. Since I have avoided using the USB-C port on the Lenovo PC to connect to the 'phone, it has worked perfectly well.
Steps to try if your 'phone won't connect to the PC:
Unplug all cables from the 'phone and reboot it.
Make sure that the USB-C cable is removed from the PC.
Plug a USB-A to USB-C cable into a USB-A port on the PC.
When the 'phone has restarted, unlock it.
Plug the USB-C end of the cable into the 'phone.
I should add that I have been using the USB-C port on the Lenovo for all my other 'phones, including a Mi Mix 2S, TCL 10, Carbon Mobile and a Teclast Tablet and all have been fine. Only the Mi 11 Lite has not worked as expected.
I hope this helps someone. It may just be something that is specific only to the Lenovo PC and the Mi 11 Lite 5G combination, but it has had me baffled for hours!
I have the same problem, I would try your solution but my Asus laptop doesn't have a USB-A but only 2 USB-C ports and no way it connects. It works ok with my pc which has an USB-A port.
So I think there's no solution for me?
Also I have another
I have an issue with Bluetooth, it doesn't automatically connect to paired devices like my car (most importantly), speaker or laptop. First I thought it was the car but since it doesn't auto connect to other devices it must be the phone(s)
I have searched for a solution on Internet but couldn't find a fix. BTW same problem on my Poco F2 pro and Oppo X2pro. All are global rom.
Has anyone a solution for this problem?
