I see -- I'll have a look, thanks. > Basically, I believe the problem your routine solved was not unique to the > PIIX3. It arose because the BIOS leaves the USB interrupts enabled and At the time of the patch the PIIX3 and the PIIX4 for which it triggers (I prepared an update for the latter shortly afterwards) could have been the only UHCI devices available. Or the only ones I had datasheets for handy. ;-) > the controller running, and it can happen on any system where the BIOS > supports legacy USB devices.

Well, the legacy support register is a part of the UHCI standard, so it should work as expected. I think the main reason for the original patch having been implemented this way and not another was the limited capability of doing in a different way back then. ;-) Maciej ------------------------------------------------------- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl _______________________________________________ [email protected] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
