Hrm, I can't quite get usb-over-ip working, I get this in the UML guest when trying to attach the host device: # usbip -d attach -r 192.168.0.20 -b 2-1 usbip: debug: usbip.c:141:[run_command] running command: `attach' libusbip: debug: vhci_driver.c:242:[usbip_vhci_driver_open] available ports: 7 libusbip: debug: vhci_driver.c:71:[parse_status] port 0 status 4 speed 0 devid 0 libusbip: debug: vhci_driver.c:72:[parse_status] socket 0 lbusid 0000000000000000 libusbip: debug: vhci_driver.c:71:[parse_status] port 1 status 4 speed 0 devid 0 libusbip: debug: vhci_driver.c:72:[parse_status] socket 0 lbusid 0000000000000000 libusbip: debug: vhci_driver.c:71:[parse_status] port 2 status 4 speed 0 devid 0 libusbip: debug: vhci_driver.c:72:[parse_status] socket 0 lbusid 0000000000000000 libusbip: debug: vhci_driver.c:71:[parse_status] port 3 status 4 speed 0 devid 0 libusbip: debug: vhci_driver.c:72:[parse_status] socket 0 lbusid 0000000000000000 libusbip: debug: vhci_driver.c:71:[parse_status] port 4 status 4 speed 0 devid 0 libusbip: debug: vhci_driver.c:72:[parse_status] socket 0 lbusid 0000000000000000 libusbip: debug: vhci_driver.c:71:[parse_status] port 5 status 4 speed 0 devid 0 libusbip: debug: vhci_driver.c:72:[parse_status] socket 0 lbusid 0000000000000000 libusbip: debug: vhci_driver.c:71:[parse_status] port 6 status 4 speed 0 devid 0 libusbip: debug: vhci_driver.c:72:[parse_status] socket 0 lbusid 0000000000000000 libusbip: debug: vhci_driver.c:71:[parse_status] port 7 status 4 speed 0 devid 0 libusbip: debug: vhci_driver.c:72:[parse_status] socket 0 lbusid 0000000000000000 libusbip: debug: vhci_driver.c:105:[parse_status] exit libusbip: debug: vhci_driver.c:311:[usbip_vhci_attach_device2] writing: 0 3 131074 5 libusbip: debug: vhci_driver.c:316:[usbip_vhci_attach_device2] attach attribute path: /sys/devices/platform/vhci_hcd/attach vhci_hcd: Failed attach request for unsupported USB speed: super-speed usbip: debug: sysfs_utils.c:23:[write_sysfs_attribute] error writing to attribute /sys/devices/platform/vhci_hcd/attach libusbip: debug: vhci_driver.c:320:[usbip_vhci_attach_device2] write_sysfs_attribute failed usbip: error: import device usbip: error: query That said, I haven't tried if it works with my patches either, so it might be something else.
