No usb connection?

Hi everyone,
I'm not sure if it's just me being a noob or if there is something borked on my P6 but I cannot for the life of me get any of my computers to recognise my P6 when I connect it via USB. I have installed the Mobile Drivers and have also tried putting it into USB Debugging mode but the computer doesn't see the phone. It does, however, charge it via USB but I get nothing else saying I'm connected and HiSuite also reports me as not being connected. Any ideas?
Ok, this is solved. Apparently, the phone's USB cable and another that I tried did not work with the phone but I swapped out to a third cable and it works fine.

Have you installed all the drivers for the G3 on your PC? Try installing LG PC Suite first and then plugging in your phone. It'll install the drivers, then use Snappea.

LG G7 EMW (Brazil - Claro) USB does not work, but charging and EDL mode do

Hi all.
I have a wonderful LG G7 (model G710EMW from Brazil carrier Claro).
Recently I've tried to connect it to my new car audio system that supports Android Auto and it didn't work as expected. Long story short, I've discovered that USB does not work on my phone.
Charging works alright, but anything that requires an USB connection simply does not work.
When I connect my phone to my PC, the phone starts charging, never shows the "USB connection" notification icon and the PC does not recognize anything. The phone also does not allow me to choose the kind of USB connection that is to be used (you know, MTP and the other options). When connected to PC through USB cable it displays exactly the same behaviour as if it was connected to a regular charger.
I have tried different cables, being two LG original USB-C to USB-A cables, an USB-C to USB-A from Xiaomi and a generic brand USB-C to USB-A charging and data cable. All of them show the same behaviour.
I did soft reset my phone, thinking maybe some app I downloaded could be interfering, but it also did not change anything. Also hard-reset, but no change either.
I've already tried replacing the circuit board with the USB plug but that also didn't change anything.
The only time USB works is in EDL mode, which shows expected behaviour. PC recognizes the "Qualcomm HS-USB QDLoader 9008 (COM3)" port and with QFIL I can navigate through partitions and stuff seems to work.
I would try installing a different ROM, but as I would need to cross-flash to unlock bootloader (default ROM does not enter fastboot) I am stuck on the USB issue now.
Has anyone seen something like this? Any suggestions to what I could try?

Hi bro, i'm from brazil too, have you tried reinstall usb drivers? have you tried on another pc? If you are using Windows 10, check on Windows update if its not blocking the drivers

I did try on another two different computers, all on Windows 10, and none of them recognized the phone except when the phone was in EDL mode.
I haven't tried installing drivers for the phone, before when it worked I never had to manually install anything for the PC to recognize my phone.
I'll give that a go, thanks!

Just to let you know, I could not find the USB driver for regular usage of the phone connected to the PC. What I found was drivers to use the phone with ADB and drivers for EDL mode.
I got to test the phone on a Linux Manjaro installation and there the computer also did not recognize any new device with "lsusb" command, whereas using a working LG G7 ThinQ the output of "lsusb" was:
Code:
Bus 001 Device 004: ID 1004:61f9 LG Electronics, Inc. Optimus (Various Models) MTP Mode
Note: the working phone had the USB connectivity option set to "Charge only" (or something like that, my phone is in Portuguese).

Galaxy s20+ stucked in "usb device not recognized"

Last time after the phone got updated (july) it cant recognized any usb cable and it pop up the message UDB DEVICE NOT RECOGNIZED. it doesnt charge anymore with cable, only way it is via wireless. Even after the september update it hasnt recovered. Practically it cant go in rrcovery mode or download mode. I tried different cables but nothing. The phone "think" it is connected via usb cable. I tried even factory reset but nothing changed.
Does anyone know what to do?
Thanks
What you can do is deleting drivers on your windows PC.
Then download the newest drivers from this site.
Install the new drivers on your windows PC and see if this worked. Good luck.

Tried but doesnt work. It cannot connect with usb cable because it has this "bug" that make the phone think that it has an usb cable attached. I am truly desperate :/
