Jason, I think this is related to handling the USB serial device. Try
another USB device - a flash-memory key for example.
Here's the results of my tests:
Host is Ubuntu Hardy amd64 8.04.1 (2.6.24-21-generic).
VM guest is Ubuntu Gutsy server (2.6.22-14-server)
hypervisor is kvm-74.
I think there is a problem with the usb_add name functions - the
host:VID:PID rarely worked for me so I always use host:Bus.Device
format.
I've got a USB-to-serial converter here too:
Bus 001 Device 004: ID 0711:0230 Magic Control Technology Corp. MCT-232 Serial
Port
Here's the output I get:
usb_add host:1.4
husb: open device 1.4
husb: opened /dev/bus/usb/001/004
husb: config #1 need -1
husb: 1 interfaces claimed for configuration -1
husb: grabbed usb device 1.4
usb_linux_update_endp_table: Broken pipe
If however I add a USB flash key:
Bus 005 Device 016: ID 0781:5151 SanDisk Corp. Cruzer Micro 256/512MB Flash
Drive
usb_add host:5.16
husb: open device 5.16
husb: opened /dev/bus/usb/005/016
husb: config #1 need -1
husb: 1 interfaces claimed for configuration -1
husb: grabbed usb device 5.16
husb: config #1 need 1
husb: 1 interfaces claimed for configuration 1
husb: config #1 need 1
husb: 1 interfaces claimed for configuration 1
and the device appears and is mountable in the VM.
