 I have a VIA chipset as well, and the patch in the link above (posted by
 Rojer, that adds the EHCI_SCFLG_LOSTINTRBUG workaround), fixes all of
 the problems with my chipset.  Without this patch, my system will hang
 and/or panic every single time a USB 2.0 device is used for more than a
 few seconds.  I've been using the patch for 2 weeeks now with no
 problems at all and ehci/USB 2.0 devices work perfectly now.
 
 My controller is a VIA VT6202.

 Michael Schout
