I am having trouble making USB work under Linux (stand alone Linux only system, SuSE 6.3). I have a SuperMicro P6SBA motherboard (PII MMX 266MHz CPU, 440BX chipset hence UHCI host controller) with AmiBios R1.5b. I have compiled kernel 2.2.16 with the 'usb-2.4.0-test2-pre2-for-2.2.16-v3.diff' patch. The error in /var/log/messages is:- "linux kernel: usb-uhci.c: version v1.184 time 01:06:53 Mar 25 2000 linux kernel: usb-uhci.c: Found UHCI device with no IRQ assigned. Check BIOS settings!". In the Bios set-up I have 'USB Function' set to enabled and 'Plug and Play-Aware OS' set to No. I have tried many other permutations of the bios settings. Has anyone made USB operational with this motherboard/Bios? Does anyone have any suggestions for a remedy? Failing all else, can anyone recommend a currently available motherboard that will provide functional USB? Any help much appreciated. Tim.
