Please try these experiments: - The latest GIT tree as of this afternoon, which merges a patch to relax some timeouts that happen right before the error messages you showed. (Including that "2msec" which looks oddly low; that'll be treated as 100msec.) - Toggle the "old_scheme_first" usbcore parameter; by default it's cleared. - Swap in some other OHCI-supporting card, such as the ones available around the corner often for $US 5/board and with a NEC high speed usb host (EHCI). - While it's getting those timeouts, and with CONFIG_USB_DEBUG still enabled, snapshot the /sys/class/usb_host/usb1/registers file with this OPTi card. Maybe I'll notice something there. Folk have problems from time to time with OPTi, but it's worked in the past. But a LOT of folk seem to be having problems with early enumeration failures lately ... not just with OHCI. Please reopen this bug if: - it is still present in recent 2.6 kernels and - you can provide the requested information. |
