I'm trying to get USB to work on my laptop (Ali Magik1 chipset, OHCI controller).. it appears that no matter what i do, no IRQ's are getting through... the OHCI controller shows up on IRQ9 and is shared by ACPI. This is the same as it is in windows.. Under windows USB works (but 'pauses' for a few seconds every couple of minutes, bus reset?).
everything else on the laptop is set to IRQ11. (well, enet, cardbus, video). I tried using setpci to change the USB irq to something unused (IRQ3).. but that didn't work (unless you use 'lspci -b' to show bus view).. either way it didn't work in practice. Using the dump_pirq program from pcmcia-cs, i get the following output: Interrupt routing table found at address 0xfdf40: Version 1.0, size 0x00a0 Interrupt router is device 00:07.0 PCI exclusive interrupt mask: 0x0000 [] Compatible router: vendor 0x10b9 device 0x1533 Device 00:0f.0 (slot 0): IDE interface Device 00:02.0 (slot 0): USB Controller INTA: link 0x59, irq mask 0x0800 [11] Device 00:08.0 (slot 1): Multimedia audio controller INTA: link 0x49, irq mask 0x0020 [5] Device 00:04.0 (slot 0): CardBus bridge INTA: link 0x48, irq mask 0x0800 [11] INTB: link 0x48, irq mask 0x0800 [11] Device 00:10.0 (slot 0): Ethernet controller INTA: link 0x48, irq mask 0x0800 [11] Device 00:07.0 (slot 0): ISA bridge INTA: link 0x48, irq mask 0xdef8 [3,4,5,6,7,9,10,11,12,14,15] INTB: link 0x48, irq mask 0xdef8 [3,4,5,6,7,9,10,11,12,14,15] INTC: link 0x49, irq mask 0xdef8 [3,4,5,6,7,9,10,11,12,14,15] INTD: link 0x49, irq mask 0xdef8 [3,4,5,6,7,9,10,11,12,14,15] Device 00:01.0 (slot 0): PCI bridge INTA: link 0x48, irq mask 0x0800 [11] Device 01:00.0 (slot 0): VGA compatible controller INTA: link 0x48, irq mask 0x0800 [11] Interrupt router at 00:07.0: AcerLabs Aladdin M1533 PCI-to-ISA bridge INT1 (link 1): irq 11 INT2 (link 2): irq 11 INT3 (link 3): unrouted INT4 (link 4): unrouted INT5 (link 5): unrouted INT6 (link 6): unrouted INT7 (link 7): unrouted INT8 (link 8): unrouted Serial IRQ: [enabled] [continuous] [frame=21] [pulse=12] If i'm reading this correctly, the board is wired up for USB to use irq 11, not irq 9...but everything wants it to use irq9. Without bios support, what can I do? Is linux's interpretation of the ALi PIRQ tables incorrect? Other files of interest follow.. any feedback would be appreciated. john.c -- John Clemens http://www.deater.net/john [EMAIL PROTECTED] ICQ: 7175925, IM: PianoManO8 "I Hate Quotes" -- Samuel L.
