Hi,

I want to use a usb3 device inside a vm.

In the following snippet it is the device with the id usb4 (See3CAM_CU55)

Code: 
qm> info usb
  Device 0.2, Port 1, Speed 480 Mb/s, Product QEMU USB Tablet, ID: tablet
  Device 2.0, Port 1, Speed 1.5 Mb/s, Product USB Host Device, ID: usb0
  Device 2.0, Port 2, Speed 1.5 Mb/s, Product USB Host Device, ID: usb1
  Device 2.1, Port 3, Speed 1.5 Mb/s, Product HID compliant keyboard, ID: usb2
  Device 2.2, Port 4, Speed 12 Mb/s, Product QEMU USB Hub
  Device 2.3, Port 4.1, Speed 1.5 Mb/s, Product USB Optical Mouse, ID: usb3
  Device 2.0, Port 4.2, Speed 5000 Mb/s, Product See3CAM_CU55, ID: usb4
qm> info usbhost
  Bus 4, Addr 29, Port 4, Speed 5000 Mb/s
    Class ef: USB device 2560:c154, See3CAM_CU55
  Bus 3, Addr 4, Port 6, Speed 1.5 Mb/s
    Class 00: USB device 046d:c046, USB Optical Mouse
  Bus 3, Addr 3, Port 5, Speed 1.5 Mb/s
    Class 00: USB device 046d:c30e, HID compliant keyboard

As you can see it is added as a device to the vm, but inside the guest I don't get anything:
* no dmesg entries when unplugging/plugging it in
* no lsusb entry

I get both of those on the host.

dmesg on the host: (when plugging it in)

am I missing any drivers or something in the guest?

The guest is running archlinux

Thanks

can you try to remove the 'usb3' from the ports where only the mouse/keyboard is plugged in?
 
two things you could try :

reorder the usb devices so that the camera comes first
use vendor/device id instead of port

also, you poweroff / start the vm everytime you change the usb options, right?
 
thanks, having the camera as the first usb device and using device id instead of port seems to have worked.
