Hi gang, I did some research on whether or not usb 2.0 card (pci and pcmcia) would work with the 2.4 kernel. If I read right, the answer is yes, they will be seen as usb 1.0 and be able to use those drivers. Is this correct? Now, if I've got problem with my stupid bios not assigning a correct irq on my built-in usb controller, will this issue pan over to a pcmcia card as well? I've got no problem getting a new card for doing this, as I'd eventually want to have usb 2.0 devices come the 2.6 (3.0?) kernel anyway. I'd just be doing it sooner (and if mandrake figures out how to circumvent my bios, I'll have 4 or 6 ports! :-) ). Wes

What is the "correct" IRQ? -- Charles R. Anderson <cra@wpi.edu> / http://angus.ind.wpi.edu/~cra/ PGP Key ID: 49BB5886 Fingerprint: EBA3 A106 7C93 FA07 8E15 3AC2 C367 A0F9 49BB 5886
The bios sets the usb controller irq to 9, which is where it also has apic. Unfortunately, the bios isn't letting that irq be shared at all and usb devices can't get an address. Reading about problems on similar laptops I found that forcing the usb irq to something else fixes it; but they don't have the solutions on their pages (though one does has a kernel patch, which I can't use). I've not gotten a response from the author's of the pages that describe the problem. So, I'm thinking that getting another controller might be a work-around...Or, how do I switch the irq? I asked this before, but still can't get a new irq to take (and the bios won't allow apic to be turned off!). Wes On Wed, 16 Oct 2002 13:08:20 -0400 "Charles R. Anderson" <cra@WPI.EDU> wrote:
