Server service crashes when client logs off

Hello,

Server service crashes when client logs off without closing Virtualhere client. Steps to reproduce:

1) Login to windows
2) Start virtual here client
3) Specify hub manually (don't know if this matter)
4) use device from server (I used usb disk)
5) Logout from windows without closing VH client
6) In half-minute VirtualHere service will stop

OS: Server - Win2016, Client - Win2012R2.
