Some kernels and laptops seem to have that problem, others don't. But I understand some systems do have working Cardbus EHCI. Are you using a relatively recent kernel? Did you see if your BIOS settings might be getting in the way? Did you try with and without ACPI? The IRQ (non)assignment is a CardBus/PCI initialization problem, not an EHCI problem. PCI device drivers (like ehci-hcd) aren't supposed to need anything special to work with CardBus ... but it seems not all the bugs have been shaken out there yet. If I were to guess, I'd say you'd likely have some PCI IRQ routing messages in your kernel messages, and they basically translate to "I'm confused about this IRQ table". If you try tweaking BIOS/Kernel/ACPI through the main alternatives and you still have no success, I'd post the "lspci -vv" output of your system to linux-kernel under a subject like "cardbus IRQ routing problem", explaining what gives. (Including any interesting kernel log messages from the PCI subsystem.) That's the quickest way to find someone who can help resolve that type of IRQ problem! - Dave _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
