Answer Question
USB Problems
Hi people,
I have a problem with USB ports of my PC. They behave in a very bad manner! The problem is intermittend and follows no specific pattern. The thing is that from time to time they lose the connected device. For example I have my PocketPC plugged in for 2 weeks and suddenly it says "USB Devive Not Recognized". So I change the port and one of them works most of the times. Until the next time. It doesn't matter what device it is. In saying this, the USB printer never seems to make any problems! The problem occurs on Windows XP SP2 and Windows Vista Beta2. So the OS doesn't seem to be a factor. Sometimes the USB ports in the back of the computer do work, sometimes the ones in the back on the bottom. The most problems are caused by the two front sockets. They don't seem to work most of the time.
So if I for example want to download my digi camera pictures or want to use my card reader, I have to go on a search for a USB port which accepts it! Very annoying.
The USB ports are USB 2.0 enabled (doesn't make a difference if I disable this) and are set to full speed in the BIOS. I already tried to change the settings with no difference. The PC is a Intel P4 3 Ghz
The system information shows 5 Intel 82801EB USB Universal Host Controllers and the 8 USB Root Hubs.
I will give the first person who gives me information which make the USB hubs work 150 points!!! Please feel free to ask any questions.
Cheers
Peter
