I cannot get USB emulated passthrough to work.
I'll be dammed! VGA passthrough - no problem, works beuatifully. What I thought would be the "easy bit" - passing through USB - well not so!
ANY suggestions as to where to look/do/try very welcome.

produces no errors on the command line. From there I can RDP to windows, all is well with it.
Connected VGA displays Windows log in screen, but no mouse/keyboard etc. - no USB
- sometimes, there is no USB power either in whcih case I need to reboot.
When there is USB power (e.g. USB mouse laser lights up) - same problem exists...
