Re: usb's dont work properly
Pls try all the usb ports at the front and at the back.
If it doesnt work, then go to Device Manager and then under Universal Serial Bus Controllers, uninstall all the USB Root Hubs tht you see and then restart the computer.
If this doesnt work, then trhe computer has to be serviced.

The USB 1.1 and USB 2.0 is a big issue regarding technology, the 1.1 has maximum speed of 12 megabits where as 2.0 has upto 480 Mbps. And all USB 2.0 devices are compatible with 1.1. Windows XP Home Edition and Windows XP Professional are both fully USB 2.0-compliant with the correct drivers.
So in your case it must work properly. But if the USB 2.0 from microsoft got currepted or badly updated by some thirdparty USB 2.0 driver then it will not work. I have been faced this problem. After doing some stuff I found that if I uninstall the USB drivers and reinstall it from microsoft driver then it works.
So, just go to the Device manager and un-install the USB drivers, then reboot the system to parmanently delete the removed driver. Then install the driver from Windows XP CD.
go to IBM web site and down load and install all your drivers, try to get any upgrades this will probably fix your problem. make sure you get the chip set drivers for sure, and the last thing you want to try is a bios flash. you could even find the ide drivers. get all that you can.
