Hi, thanks for the reply.
Looks like the USB is working. I've got some USB related messages that look like this:
uhci_hcd 0000:00:10.0: UHCI Host Controller
uhci_hcd 0000:00:10.0: new USB bus registered, assigned bus number 1
uhci_hcd 0000:00:10.0: irq 10, io base 0x0000d000
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 2 ports detected
ACPI-0212: *** Warning: Device is not power manageable
ACPI: PCI Interrupt 0000:00:10.1[B] -> Link [LNKE] -> GSI 10 (level, low) -> IRQ
so it looks like its finding the ports but not recognising anythings plugged in.
The device is a Crucial 128mb pen drive.
