[Xen-users] XEN 4.6 / 4.9 - PCI-Passthrough USB 3.0 win7 / Win10 not working

[XensemannIMAP <xensemann@xxxxxx>]

Hey there,
for a Continuous Integration System I need to pass through a PCI USB3.0
card to my virtual machines.

For 16.04 and winXP this is working great! The PCIe Card appears in
Windows device manager, the attached USB-Device shows up in the device
manager and works like a charm.

However, this is not possible for my system with win7 and Win10 and the
very same setup. I've tried is with xen 4.6 and xen 4.9. In those
versions PCI-Back is build in in the kernel as a model. So as far as I
got this, grub pciback command lines are not working for this. So the
card is touched by the normal USB-Driver of my 17.10 host. I tested it
with both types of PCI-Cards, some of them haven't supported FLReset and
one did support FLReset (1b6f:7023 Etron Technology Inc. EJ168 USB3.0
Host controller).

The Result is: all are not working in win7 and win10. All Cards appear
in the device manager and the driver can be installed manually.
Afterwards some devices have trouble to boot (code 10) other do not show
any error but connectet usb-devices say:"Can't reset device". Etron does
not show up any connected USB-Devices. In short => not working.

# Questiones running arround my head:
-> Why is this working for XP and Ubuntu 16.04, even if thoise USB-Cards
do not support FLReset.
-> Why is it not working for Win7 and Win10, what is different with
those OS?
-> In the www there are only a view reports about PCIe-USB-passthroughs,
has somebody made it to pass a PCIe USB 3.0 device to your win7 or win10
machine? Which configuration have you used?


Thx for reading so fare, below you'll find some infos about the system.
All the best!
