ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver
(PCI)
ohci_hcd 0000:00:07.3: Contaq Microsystems 82c693 (#4)
ohci_hcd 0000:00:07.3: new USB bus registered, assigned bus number 1
ohci_hcd 0000:00:07.3: irq 10, io mem 0x09018000
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 2 ports detected
Thanks a lot -- this should get included in mainstream, at least for the
