I have the following USB devices on a Linux server:
# lsusb -t /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/2p, 480M |__ Port 1: Dev 2, If 0, Class=hub, Driver=hub/6p, 480M |__ Port 2: Dev 3, If 0, Class=HID, Driver=usbfs, 1.5M |__ Port 3: Dev 4, If 0, Class=hub, Driver=hub/4p, 480M |__ Port 1: Dev 8, If 0, Class=print, Driver=usbfs, 12M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/2p, 480M |__ Port 1: Dev 2, If 0, Class=hub, Driver=hub/6p, 480M
I would like to pass the entire USB hub (Dev 4) to a Windows XP guest. In this a device attached and removed to the hub should be automatically handled by the guest (right?).
I tried the following code with
<hostdev mode='subsystem' type='usb' managed='yes'> <source> <address type='usb' bus='0x002' port='1.3' /> </source> </hostdev>
but it didn't work:
error: Failed to attach device from attach_hub.xml error: internal error usb address needs device id
What am I doing wrong?
