When the usb devices have to be removed from configuration the conf file has to be changed. Use "qm monitor" and "info usbhost" instead!
More details about ports can be found here - but note as already mentioned the "lsusb -t" call is not reliable. Therefore the form specifying bus and port is used: Cruzer Blade # -usb host=Īccording to the above example let´s say the Alcor stick and the Cruzer Edge connected to the external hub (which is device (4) from the example) should be assigned to VM 804:įor the Cruzer Edge this form will not be sufficient - there are two devices from the same type. This is the simplest form and sufficient in most cases.īus 002 Device 004: ID 0781:5567 SanDisk Corp.
Ethernet Network adapter USB 1.1 behind the same USB hub as above. memory stick Alcor behind the same USB hub as above. memory stick SanDisk USB 2.0 behind a USB hub. In order to demonstrate how devices, physically connected to the host can be identified it´s assumed the following 7 USB devices are currently connected: Shutdown the VM (if running) and start it again.Īlternate way: pass the USB port to the guest Example Simple Way: pass the USB device ID to the guestĪssigning an Alcor memory stick connected to the host to VM 804.įigure out in the host the Device Type byīus 002 Device 013: ID 058f:6387 Alcor Micro Corp. The assignment of such devices can be predefined in the configuration file or "plugged" into the VM while it is running. LSUSB DETAILS DRIVER
Special device which needs a driver which exists only in the VM. Separate NIC for the VM, but Direct I/O not avaiable. There can be good reasons to access to USB hardware directly from a guest as it would be part of the VM itself, e.g.:
