Windows VM problems with external usb drive

Hi,

I have WD My Passport encrypted drive. I wan’t use it on Qubes. I remember I can use it under Virtualbox. This drive shows to OS two usb volumes, one as encrypted drive, and the second as virtual cd with unlocking windows tool. sys-usb seems to see everything correct. But when attaching it to Windows VM with installed QWT and stubdom-qrexec 1 I hear windows attaching and removing device sound. In best case I can see in device manager some broken usb device…
