Has anyone managed to get this motherboard's (tyan tsunami AT) on board usb to work? I'm currently using an add on pci card to use the usb devices I have but would _love_ to free that PCI slot up. Specifics: Tsunami MB (AT Form factor) Single processor: model name : Pentium II (Deschutes) stepping : 2 cpu MHz : 334.095 cache size : 512 KB Bios Version 1.16 USB Controller: 00:07.2 USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01) (prog-if 00 [UHCI]) Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 32 Interrupt: pin D routed to IRQ 9 Region 4: I/O ports at ef80 [size=32] 00: 86 80 12 71 05 00 80 02 01 00 03 0c 00 20 00 00 10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20: 81 ef 00 00 00 00 00 00 00 00 00 00 00 00 00 00 30: 00 00 00 00 00 00 00 00 00 00 00 00 09 04 00 00 Symptoms: The kernel detects the hub just fine: usb-uhci.c: $Revision: 1.259 $ time 11:21:32 May 26 2001 usb-uhci.c: High bandwidth mode enabled usb-uhci.c: USB UHCI at I/O 0xef80, IRQ 9 usb-uhci.c: Detected 2 ports usb.c: new USB bus registered, assigned bus number 1 hub.c: USB hub found hub.c: 2 ports detected However pluging _anything_ into that hub just don't work, Lots of error messages about EMI, usb-uhci.c: interrupt, status 3 frame# <blah> Device disconnects etc etc. Needless to say said device never gets initalized, though it is detected as being inserted. So just to be sure I went and got another pair of usb ports to connect to the header. No joy. I tried with an external (powered) hub and things atleast got initialized but was still unable to use the devices (went into that spew about usb-uhci: interrup, status 3, frame# <blah> over and over again) Pokeing around I see that the mother board's bios will _always_ assign the usb controller to IRQ 9, what makes me wonder a bit is this next bit from lspci: 00:07.3 Bridge: Intel Corporation 82371AB PIIX4 ACPI (rev 02) Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Interrupt: pin ? routed to IRQ 9 00: 86 80 13 71 01 00 80 02 02 00 80 06 00 00 00 00 10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 30: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Thats also routed to IRQ 9 (could this be the problem?) However _this_ USB controller works just fine: 00:13.0 USB Controller: VIA Technologies, Inc.

I've tried kernels 2.4.0 -> 2.4.5 all with pretty much the same result (except 2.4.4 which oops on boot in the usb controller ;) ) I've rummaged around on the linux-usb lists and didn't see anything there. So is this a known problem with this motherboard/bios version?
