Just went through a nightmare trying to get USB working on one of our Athlon/VIA machines here, and after much trolling through the archives for the lists here and not seeing exactly the right solution, I figured that I'd mail off some info here as to how we got this to work....
Short version of the problem is the "classic" bulk transfer timeout problem or problems with the devices not accepting their USB ID numbers when given one from usb-uhci. Our machine that experienced the problems here was an Athlon 1GHz running on an AOpen AK73Pro motherboard, which uses the VIA-686A chipset, all running RH-7.3. FYI, we also had the same problems on this machine with RH7.1, RH7.2, MDK8.0, and MDK8.1 (SuSE-7.1 worked, but was more than a bit out of date for some of the other things we wanted). After much fighting, pulling of hair, and many long hours spent going through testing out various debug builds, kernel revisions, etc., I finally found a single item that made a total world of difference..... In the BIOS, take the "Assign IRQ for USB" option and turn it off. After doing that, everything worked perfectly. While fighting with it, we'd tried re-assigning IRQs, tried turning off APM and ACPI, shuffled PCI cards around to different slots, re-installing different kernel revisions and all sorts of other things. In the end, though, turning off the IRQ for the USB controller made all the difference. I'd spent so much time fighting with this one, though, that I figured I'd fire a note back to the list here so that this at least ends up in an archive somewhere; hopefully its got enough keywords in it to get caught by someone doing a search for the same problem. Please note, though, that I'm _not_ on the list; if you have questions then you'll need to email me directly. -- Graham TerMarsch Howling Frog Internet Development, Inc. http://www.howlingfrog.com ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Stuff, things, and much much more. http://thinkgeek.com/sf _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
