VIA hasn't been forthcoming ... we can do no better! :) The main issue I've had with it has been timing-related problems, related to queue processing, and a patch I'll post later today might make some of those go away. Those symptoms are unrelated to what you show below. > I've got one, but cannot get it to work with ehci_hcd (from > 2.6.9-1.6_FC2 kernel).

Is your VT6202 on a PCI add-in card, or a motherboard? My best guess is that the "fatal error during startup" issue has to do with power switching, since those started to crop up at about the time the driver started to forcibly power all ports off during startup (to handle some devices that didn't seem to want to enumerate without a power cycle). Maybe the powerdown needs a delay, or the powerup delay needs to be more than the 20 msec guaranteed by the EHCI spec ... but violating those timings doesn't seem like the sort of thing that'd make any EHCI controller resort suicide. - Dave ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
