System information ---------------------------- Welcome to SUSE LINUX 10.1 (i586) - Kernel Linux version 2.6.16.13-4-smp (geeko@buildhost) (gcc version 4.1.0 (SUSE Linux)) #1 SMP Wed May 3 04:53:23 UTC 2006 scanModem update of: 2006_December_25 USB modem not detected by lsusb Modem or host audio card candidates have firmware information: PCI slot PCI ID SubsystemID Name ---------- --------- --------- -------------- 03:05.0 11c1:048c 11c1:044c Communication controller: Agere Systems V.92 56K WinModem Modem interrupt assignment and sharing: --- Bootup diagnositcs for card in PCI slot 03:05.0 ---- PCI slot PCI ID SubsystemID Name ---------- --------- --------- -------------- 00:1b.0 8086:2668 103c:2a09 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW Modem interrupt assignment and sharing: 169: 24689 0 IO-APIC-level uhci_hcd:usb5, HDA Intel, cx88[0], cx88[0] --- Bootup diagnositcs for card in PCI slot 00:1b.0 ---- ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 16 (level, low) -> IRQ 169 PCI: Setting latency timer of device 0000:00:1b.0 to 64 === Finished modem firmware and bootup diagnostics section. === === Next deducing cogent software === =================================== The modem interrupt (IRQ) is 255 . IRQs of 0 or 255 are not functional!! The CPU cannot control the modem until this situation is corrected!! Possible corrections are: 1) Within the boot up BIOS, change from a Windows to a non-PNP/Other Operating System type. Instructions for accessing BIOS are at: http://linmodems.technion.ac.il/resources.html within: Additional Resourcces. 2a) Add an option "pci=routeirq" to the kernel boot up line. Here is an example paragraph from /boot/grub/menu.lst : title Ubuntu, kernel 2.6.15-26-686 root (hd0,6) kernel /boot/vmlinuz-2.6.15-26-686 root=/dev/hda7 ro pci=routeirq initrd /boot/initrd.img-2.6.15-26-686 savedefault 2b) Same as above, but use "pollirq" instead of "pci=routeirq". 3) Within some BIOS setups, IRQ assignments can be changed. 4) On non-laptop systems, moving the modem card to another slot has helped. 5) Sometimes upgrading the kernel changes IRQ assignment. ===================================== I tried combinations of pci=routeirq and changing the BIOS settings to non-PNP. This did not remove the IRQ error message from ModemData.txt when I ran the ScanModem script again. I have no open PCI slots and do not really want to swap locations of existing items. Is my modem supported? If not, are there any external, ideally USB or Ethernet, non-winmodems? Thanks for the help in advance.
