Hi, I''ve successfully passed 2 different USB devices (one at a time) to a domU running Ubuntu 9.10. Each time, the devices were extremely slow. I passed through a USB hard drive. The domU recognized the hard drive, but mounting it and bringing up a directory listing took minutes. I then passed through a USB DVD-RW....basically an ATAPI DVD-RW in an USB enclosure. Again, domU recognized the drive but when I tried to burn a DVD iso it just sat there. The DVD-RW light came on occasionally but for the most part nothing seemed to happen. I''m running XEN 3.4.1 with a Centos 5.3 dom0. I''m not sure where to being looking. Does USB passthrough support USB 2.0 speeds? I''d really like to pass the USB DVD-RW through and eventually I want to pass a USB video encoder to a different domU.
