good morning community

On my old DEV Server with Proxmox 3.4, running on a ASUS P7P55D I was able to passthrough 2 external drives with USB 2 and one external USB 3 drive connected to USB 2 ports w/o any problems. I passed the USB drives to a Windows 8.1 VM and the behavior was rock solid.
On a fresh installed Proxmox 3.4, running on a ASUS Z87 Deluxe Motherboard I face some strange issues I'd like to share with you.

Picture of the manal with the USB Ports : http://cl.ly/image/3f1o0s471p0w
here some details about my current configuration on the new DEV Server on the ASUS Z87 Deluxe MB :

Code:
root@vmonster02:~# lspci | grep USB
00:14.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB xHCI (rev 05)
00:1a.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #2 (rev 05)
00:1d.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #1 (rev 05)

USB host infos on the running VM

Code:
qm> info usbhost
  Bus 4, Addr 3, Port 3.2, Speed 5000 Mb/s
    Class 00: USB device 1058:107c, Elements 107C
  Bus 3, Addr 4, Port 6, Speed 480 Mb/s
    Class 00: USB device 1058:1021, Ext HDD 1021
  Bus 3, Addr 3, Port 5, Speed 480 Mb/s
    Class 00: USB device 1058:1021, Ext HDD 1021

VM configuration
Code:
vi /etc/pve/qemu-server/119.conf
usb0: host=4-3.2
usb1: host=3-5
usb2: host=3-6

Problem description
With the above configuration I just see the 2 external drives connected to the USB 2 ports (usb1 and usb2)
The USB 3 based external hard (usb0) drive is not visible in the windows 8.1 guest system. in the device manager I see an error about wrong Vendor description. Therefore the Device won't show up.

I double checked with the available documentation:
https://pve.proxmox.com/wiki/USB_Devices_in_Virtual_Machines
https://pve.proxmox.com/wiki/USB_physical_port_mapping

Does someone of you had similar issues and can provide a solution or point me in the right direction ?
cheers
tom
