It's some kind of IRQ setup problem, that's all -- not a USB issue. ACPI, APIC, LAPIC, and IOAPIC settings may all need adjustment. Also, try the latest kernel (2.6.11-rc2), there are constantly changes to fix IRQ setup problems. - Dave > hub 1-0:1.0: port 1, status 0100, change 0000, 12 Mb/s > ohci_hcd 0000:00:0f.2: GetStatus roothub.portstatus [1] = 0x00010101 CSC PPS > CCS > hub 1-0:1.0: port 2, status 0101, change 0001, 12 Mb/s > hub 1-0:1.0: debounce: port 2: total 100ms stable 100ms status 0x101 > ohci_hcd 0000:00:0f.2: GetStatus roothub.portstatus [1] = 0x00100103 PRSC PPS > PE > S CCS > usb 1-2: new full speed USB device using ohci_hcd and address 2 > > ==> ohci_hcd 0000:00:0f.2: Unlink after no-IRQ?
