Howto debug BSOD when connecting, disconnecting USB

Question

I am running Windows XP, SP3, all updates installed.

When I plug in or disconnect a USB device, I get a BSOD:

0000007E or 000000BE

and the two drivers that are listed are either fastfat.sys and kmixer.sys.

I've uninstalled all USB devices in the Device Manager, I'd re-installed my WACOM drivers, all to no avail.

I am not sure how to proceed in debugging this.

Any thoughts?

Might be useful if you could elaborate on what types of USB devices trigger the error - peripherals, flash drives, external HD, everything, etc?
Sure... USB jump drives, MicroSD cards plugged into USB adapters, SD card plugged into the front media slot, Western Digital 2.5" passport drives, etc.

Have you tried running the system file checker to verify that all the system drivers are undamaged/unmodified?

The MS Knowledge Base Article on the STOP 0x0000007E error (aka SYSTEM_THREAD_EXCEPTION_NOT_HANDLED) provides some general advice on things to try.
It looks like you've tried a few already, but it's probably worth a look.

I can't find a dedicated article for Stop 0xBE, but the friendly version of the error is ATTEMPTED_WRITE_TO_READONLY_MEMORY, and from what I find its causes can be much wider (bad drivers, bad software, bad hardware, bad BIOS, and so on). So that doesn't helps much.

Along with DMA57361's suggestion of checking for corrupted system files, the kmixer.sys is a sound driver, you might see if there is an update for your sound driver, also scan your system for malware or a rootkit.
