Description Sergey 2007-06-08 21:32:58 UTC
I have old computer :) and bought VIA PCI USB controller. Mouse and 
printer/scanner works fine, but when i connect a usb drive or card reader, 
system becomes work very slowly. Deattach of usb drive/reader does not take 
effect. Disabling udev,dbus and hal services does not take effect too :(

oh, software enviroment is same :) just i had compile kernel for MB
Comment 6 Greg Kroah-Hartman 2007-09-05 07:03:46 UTC
Still, VIA controllers are known to be buggy and VIA is not willing to work with us to try to fix issues like this. The bugs can be caused by timing issues, so they might not show up on other hardware.

There's really not much we can do here about this, I'm very sorry.
