Trying to connect phone to Qubes os(4.0)

[Tae Hwan Kim]

Hi.

I am trying to connect my android phone to my work vm in qubes os. So I tried this.

1. Changed AppVM(work) to HVM because PVH mode no PCI passthrough which I am trying to do.

2.

lsusb

Bus 001 Device 002: ID 1004:61f9 LG Electronics

3. And then I did

readlink  /sys/bus/usb/devices/usb1

and it returned

../../../devices/pci0000:00/0000:00:14.0/usb1

4. finally

qvm-pci attach --persistent work dom0:00_14.0

But it says "empty response" and doesn't work.

I followed this step.

Am I doing right? In the result of lsusb says my usb connected in Bus 001 so I did

readlink /sys/bus/usb/devices/usb1 instead of usb3(in document). Did I do it correctly?

In final step I just changed : to _ like 00:14.0 to 00_14.0. 
I tried dom0:00:14.0 but doesn't work

This looks valid.

Is your USB controller already assigned somewhere else, like sys-usb by
default? If so, you should try to assign just the USB device to your
work qube first instead of the controller with qvm-usb (see --help for
options). If you have and it isn't working, you might need to shutdown
sys-usb before you can re-assign a controller it is using. qvm-pci by
itself will show which devices are assigned to different qubes in the
USED BY column. You will often need to include the no-strict-reset
option with USB controllers.

Thanks for your help.

I  just created sys-usb app vm following this guide.

And sys-usb app vm finds phone automatically, so I just attach it to work vm.
