In a pc and laptop I have usb port problem, some ports are working and some ports are not working i.e no response, while device manager shows usb hardware is working properly. Is there anyway or tips tricks to recover the not working usb ports?

removing drivers and reinstalling is the easy fix. If still having problems try google / youtube.

He was an old person... no parkinson, but seemed that he thought that usb was like a slot machine... that you can plug in in any way he wanted.... you can imagine how was the notebook connector state. Other case, with my children... pulling usb cables, and not aligned with the connector is nor a good idea.... for the connector AND the cable...
Besides that, sometimes usb drivers doesn´t work properly, but be careful, they usually work fine. Title: Re: pc usb connector problem Post by: token0 on December 27, 2020, 03:42:57 15:42 To diagnose if USB problem is software, I recommend this:
1. Run linux, live-usb will suffice. I recommend debian or ubuntu. 2. run terminal command Code: sudo lsusb example output: Code: Bus 005 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub 3. run terminal command Code: sudo dmesg -Hkw Code: [Dec27 17:33] usb 3-1: new full-speed USB device number 2 using ohci-platform ctrl-c to exit If you had zero output on some ports, then problem is in hardware. |
