I can verify this problem isn't in 2.6.15-25-386 but is in 2.6.15-26-386 and edgy 2.6.17-7-386. "sudo rmmod ehci_hcd" allows the device to work but at USB 1.1 speeds. This is on an Averatec 3250 laptop. Via south bridge, USB 2.0 PCI ID 1106:3104 -- Unlink after no-IRQ https://launchpad.net/bugs/24925
