SEP and Vshield integration

Hi Experts,

Since our office going to implement VDI structure and all clients with SEP12.1 licenses purchased. So our concerns is whether we need to buy additional or upgrade if we migrate our infra to VDI with Vcenter environment.Please advise me on below:

1) How can we control USB device auto scanning in VDI environment?

2) Do we need to purchase additional license for VDI environment?

Thanks guys.
