ISDN modem problems (IRQ?)

By boschke ·
Hi,
I seem to be having problems getting hisax to find my Teles.BRI/PCI ISDN modem. (have tried passing type=21 to hisax module, but it won't find the card).
According to lspci or scanpci it's there all right, on IRQ 10. The problem is not the card itself, since it works fine with win95/98/2k.
Could the problem be that my USB controllers also have IRQ 10? If so, is there a way of forcing either USB controllers or ISDN modem onto another IRQ?

I am using Mandrake 8.0, with hisax and isdn4linux that came bundled with it (should be recent enough, no?)

Thanks in advance!

check your system bios there should be way to disable your USB ports there if your not useing them. you could make sure that bios is to NO or Disable for PnP and then you could give out IRQ's via Bios. A bit tricky depending on your system's Bios. your *nix box might be holding the USB's open unlike winO/S that leaves them closed so you would not get a conflict. I'm not familure with Mandrake though.

I would say disabling the USB in BIOS completely is not an option, since this is actually a win2k box, with Linux added to it (other people using this box are windows users), and USB is needed in win2K.

I have tried changing the IRQ for the second PCI slot (forcing it to some value), but for some reason, the BIOS then also changes the IRQ of the USB ports to the same value...

Also, The linux kernel should not be contacting the ports, since I have disabled the USB daemon service under linux, and the module allowing the kernel to support USB is not loaded either (can it still cause conflict even then?).

Sorry,
Thanks for taking the time to answer though...
