pc usb connector problem

[max]

Hi,

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?

Regards

if your device is seen in some ports but not orthers, remove the drivers and then Scan for hardware changes.
removing drivers and reinstalling is the easy fix.
If still having problems try google / youtube.

I have a faulty USB port on my Works Laptop, device manager does not show up any issues, it only measures 2.5v if you measure the O/P voltage on the faulty USB port, whereas the other ports are ok @ 5V - I must say that i damaged this port with one of my projects (I must use an external USB hub in future)

you can try this small free program to analyse your USB ports. Very helpful.

A few years ago, someone asked me about a failing usb port... 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.

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

to list all live USB devices

example output:

Code:

Bus 005 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 1130:f211 Tenx Technology, Inc. TP6911 Audio Headset
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

3. run terminal command
    

Code:

sudo dmesg -Hkw

to display kernel log messages in real time; at this point connect your working USB device to USB ports of your PC and look at kernel log messages. If USB port is working, you will see output like this:

Code:

If you had zero output on some ports, then problem is in hardware.
