I'm happy to report that Qubes works with Signet hardware!
As you would expect, the USB device can only type into the qube to which it is attached. You'll need a usb-qube in order to pass the device through to a qube, which is usually set up at install time.

There seems to be a problem with Qubes 4.2 not passing through raw HID devices, but I've started a thread about it on the Qubes forum and am trying to get to the bottom of it as quickly as possible.
Since I used both Qubes and Signet daily before upgrading from Qubes 4.1, this is kinda important for me! It's seriously disrupting my workflow!
