[NTLUG:Discuss] IRQ problems preventing my printer setup

Wed Jun 6 13:11:03 CDT 2001

I do not know of anything "Particular" to this situation, but some
additional info would help to solve this problem.
Does this setup work under windows if applicable?? You will only recieve
support from vendors for windows platform most likely.
Does any other USB devices work? dmesg doesnt show any, so I cant tell if
you have any.
If you do have everything loaded for USB to work, do you have the USB
printer driver module loaded, or built into the kernel? 
	lsmod should show printer.o if loaded as module
Kernel version ?? I do not know what ships with RH 7.1, but I thnk that the
first 2.2 series to have USB support was 2.2.18 Of course 2.4 has it also.
If it is earlier version, RH may have made some mistakes backporting it.
Of course, as you noted last time, your bootup shows a possible IRQ
conflict, theres alot of possibilities, and things to look at, even if
thats not causing a problem, you may want to try to resolve that.

Hope some of this helps :)
