No USB functionality

Post by podge69 »

I have a BP6 with dual Celeron 433's running Windows XP Pro (with SP2). Somehow, I have completely lost the functionality of both USP ports even though I've updated all USB drivers.

I tried to solve the problem by fitting a PCI USB card - in fact, I tried with 2 different cards. In both cases, the drivers loaded and Device Manager indicated that all devices were working properly and showed nothing that needed attention.

When I attempt to connect to a USB port (either one of the motherboard ports or on the PCI card), the system freezes and I have to reboot. Sometimes (but usually not). there is a message that the device canot be identified.

Any ideas?

Use Knoppix to boot it into Linux to see if Linux reports the USB devices correctly or not when you hook them up.

What manner of device is it that you are attempting to connect to the USB port when the system locks up? I have experienced a similar problem if I attempt to connect a USB wireless networking adapter to my PCI USB 2.0 adapter card ports while at the same time using a Hollywood Plus MPEG decoder board. To date, my only solution has been to connect the wireless networking adapter to one of the onboard USB 1.1 ports. This curtails the transfer speed of the adapter from 54 Mbps to 11 Mbps but it prevents a system lock-up.

How long has your PC been on before you plug them in?

For me, i frequently lose control of all my USB devices, both onboard and on my PCI USB 2.0 card.

I'm heavily overclocked causing my chipset to overheat occasionally. When it does, instead of freezing or crashing, it just kills the USB.

It doesn't crash when I plug in devices and it's overheated, but maybe you should check your temperatures.

Also check your PCI/PNP configuration in the bios and device manager. You might have some conflict windows isn't making obvious. Then maybe try disabling ACPI.

Good luck!
