Solved USB not working on an Asus P5L-MX mb with XP

August 26, 2014 at 13:25:03
Specs: Windows XP, 3 GHz / 2 GB
Everything started with a system message in the tray: a device attached to your usb port is not working.
I neglected the message but after a while an error sound started from my pc speaker and in the end the system blocked.

I tried from the device manager to update the USB controler driver, or to disable it and to reenable but in the end the error sound appeared and the system blocked. I surveyed the cpu and mb temperatures, but nothing could be related to the appearance of the error.

In the end I disabled the USB function from the mb BIOS, abandoning my 4 usb ports.

This was the only way to stabilise the computer.
Previously I checked the computer for viruses, and I restored an older image of the system disk. Nothing worked.

Any ideas to get back my 4 usb ports?
Thank you!

Sure Derek,

I fixed it by putting a PCI card with additional USB ports.

I could not trust anymore the integrated USBs, because of their random behaviour.

Can you help understanding please - what do you mean by system blocked?

Were there any errors appearing in Device Manager?

Always pop back and let us know the outcome - thanks

As I was mentioning, after the error message appeared several time in the tray "a device attached to your usb port is not working", and while I was working on the computer, an error sound started from the computer speaker and the system blocked, i.e. it freezed, no command taking, anything.. A reset, from the button, was necessary, in order to restart the system.

In the Device Manager, previously to the blockage, there was no error.

What happens if you remove all USB devices except essentials (mouse and keyboard maybe) then put the USB's back in BIOS?

I have tried this (the mouse and the keyboard are not on USB), so I had nothing on the 4 USB available.

I reput the USB function in BIOS, the system started, worked for a while, then the error sound appeared and the system freezed.

So honestly, now I work with the USB function disabled, and the system is stable. I use email to transfer files to the computer, as I cannot use any external HDD (conectable on the USB).
The greatest problem I have is with the printer, HP 990 cxi, which has only USB cable to connect to the pc, so I print from the laptop...

Hard to say but, assuming that you have the latest drivers from your computer manufacturer one possibility is a bent pin in one of the USB sockets that shorts out at times. Note, it's not that you necessarily need the "latest" drivers but that installing them often sorts out a corrupted driver issue.

I agree with you on both issues:

- a bent pin. For this I studied with a flash and a magnifier each USB port. Unfortunately, you could not see much, but from the little I saw there was no bent pin. On the other side, I opened the PC, look at the mb in order to reach to the USB terminals, but they are surrounded with a metalic screen and also you can not reach their terminals as they are covered by the PC frame.
I would have to completely remove the mb in order to reach the USB terminals, thing that I consider too much..
- a corrupted driver. I tried to uninstall and reinstall the drivers. I managed it, but with no results.

I personally believe it's one of the USB controlers on the mb, a defective integrated circuit. Which is a dead end.
My only solution which I foresee is a PCI card with additional USB ports, mounted on the PCI connector. I will try to speak with an IT dealer.
Tks

Sounds like a plan and you may well be right on this.

Presumably the individual USB sockets are in discrete blocks to there is no way to disconnect individuals to prove the point. The only time I ever had trouble with sockets was some old cheapies that had open wire pins which definitely could touch together.
