Specs: Windows XP, 1GB, Intel
Hi There,
Here I'm facing a problem with my PC. Whenever i insert pendrive or any other mas storage device to the USB port, the PC become busy and not responding. In such situation the PC should be restarted then only the USB device connected is recognised.
This trouble is not at all always. Some time the PC recognises the USB without restarting the PC. But most of the time USB can not be recognised unless the PC should be restarting. Can anybody fix this error for me or any resonable solution from ur side pls.

USB devices may not work correctly when they're connected to certain USB ports e.g. ports in a hub or on the front of a desktop case. If you have a desktop computer, you may have an IRQ sharing problem you need to fix, or your power supply may be starting to fail.
See response 3 in this:

Also - if you are using a USB extension cable, some of them have inadequate wiring and will not work properly with some USB devices.

Have you re-loaded Windows ?

Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.

Load the main chipset drivers first.
