"appear to work" - do they work or don't they? Are you using the same host hardware? I have a situation were several devices works on a computer with UHCI interface (Linux 2.4.20). Same device does not work with OHCI (but I do get the interrupts). Works on another computer using OHCI (but this was using an older linux kernel). I will investigate this furter when I get back to work - collecting info right now. Summary: If it does work with 2.4.18 kernel but not with a 2.6 (or 2.4.20?) on the same HW then it would be very interesting to find out why. But if it is not the same HW (including the host side) - then there are a lot of possible causes (BIOS, actual hardware - like bugs in OHCI HW implementation, drivers, ...) > Unfortunately running 2.4.18 kernel is not > an option for me as I have a few other problems with it and I need > some of the new stuff in 2.6.x kernel anyway.
