OK, I have a Asus A7V333-X which has an USB 2.0 controller. I use the uhci.o kernel module for USB 1.x support, and that works great (like, devices are recognized), and an up-to-date gentoo system with the ck6-kernel.
Now I have an external harddrive with USB 2.0 capability. It works if I do not load the ehci-hcd module, but of course only as an USB 1.2 (or so) device. But it is recognized and works with usb-storage.
But if I load the ehci-hcd module, nothing works any more. I think it's a problem with the IRQ routing, but I tried nearly anything that's possible (enabling/disabling plug&play-OS in BIOS, playing with the kernel parameters from the FAQ), but it only got worse (p&p enabled+ kernel acpi=off =>> no more IRQ assignable...). I checked /proc/interrupts, and there are no more interrupts for acpi/uhci/ehci after the ehci-module is loaded, so it's really obvious that it has something to do with the IRQ routing.
So, has anybody experiences with this motherboard and USB 2.0, or any other suggestion?
thanks, Lars
