I'm using linux 2.2.16 with usb-2.4.0-test2-pre2-for-2.2.16-v3 and
ide.2.2.16.all.20000805 patches applied. I have a SuperMicro S2DGU
motherboard. Its got a PIIX4 USB chipset.
I just got a Canon BJC-2100 printer, which has a USB port. I'm trying
to use both it and my Promise Ultra66 controller at the same time. I
can't.
If I disable USB in my BIOS, the Promise controller works fine, but of
course the USB code can't see my printer.
*f I enable USB in my BIOS and use the standard UHCI USB driver, the
Promise controller works fine, but the USB driver doesn't see my
printer.
If I enable USB in my BIOS and use the JE UHCI USB driver, the USB
driver sees my printer but then the Promise controller doesn't work --
I get the error "ide2: ports already in use, skipping probe" and the
same thing for "ide3".
I've tried moving the Promise controller to a different slot. I've
tried assigning it a different IRQ explicitly in the BIOS (that seems
to have no effect). I don't know what else to try.
I've put the output of "dmesg", "cat /proc/interrupts", "cat
/proc/ioports", and "cat /proc/pci" up on my home page so that anyone
who might be able to help me solve this problem can look at them
without cluttering up the Usenet with all that data.

If you can provide any insight into how I might solve this problem,
I'd be extremely grateful. If there's any other information I can
provide that would help you, please let me know.
Thanks!
