Upper Mail in short: Tried to passthrough a PCI-USB-Card to Xen
Win7/Win10 HVM. Tested 5 Cards without success.

Update:

After lot's more testing I tried to passthrough the onboard USB-Controller
to a win7 HVM. This, how ever is working !!! =)
So fare it is working, devices like a mouse is detected and I can move the
pointer. 

But the old questions are still open:

-> Why is passthrough of USB-PCI-Cards working for XP and Ubuntu 16.04,
even if those USB-Cards do not support FLReset.
-> Why only internal USB-Host Controller is working for Win7?
-> Why is it not working for Win7 and Win10, what is different with
those OS?
-> Has somebody had the same trouble with non-motherboard PCI-USB-Cards?
-> It is not the missing Abilety of Xen passing something to Win7, it is
a Hardware or a driver Issiue. But the hardware is working for XP and 16.04
it have something to do with the driver?
