Windows XP Bluescreen when unplugging printer

[Erik Rull <erik.rull@rdsoftware.de>]

Hi all,

I want to run an epson inkjet within my windows xp guest. my host has 
enabled usb 2.0, the USB flashdrive works without any problems. When I plug 
in the printer (works with the same drivers on a native windows xp!), it is 
recognized and the status monitor shows also the ink levels. Until I start 
printing. Then the ink level disappears and the status monitor hangs. The 
printer itself doesn't do anything, no LED blinks, no printing starts. When 
I shut down windows or unplug the printer I get a bluescreen in XP on 
usbuhci.sys

Interesting: When I switch off USB 2.0 and enable only USB 1.x in the host 
BIOS, everything related to USB is SLOW (usb flash drive, too!) but the 
printer works (also slow, but it prints).

Any ideas what could cause that behaviour? Comes up with kvm-88 and kvm-77 
as well.

I tested it on two different systems both the same behaviour.

Best regards,

Erik
