USB pass trough with equal vendor and device ID

[zebra]

Running v3.1 with an Win8.1 VM

info usbhost in monitor gives:

Bus 2, Addr 15, Port 1.5.6, Speed 12 Mb/s
Class 00: USB device 10c4:ea60, CP2102 USB to UART Bridge Controller
Bus 2, Addr 17, Port 1.5.4, Speed 12 Mb/s
Class 00: USB device 10c4:ea60, CP2102 USB to UART Bridge Controller


As you can see, the two device have the same vendor/device ID


Normally I use: device_add usb-host,id=usb1,vendorid=0x0403,productid=0x6001
that works for the other devices I use but now I am lost.
I have also tried: device_add usb-host,hostbus=2,hostport=1.5.6 but had no luck


On a side note: every restart of the VM I have to add them again. Wish I could make these settings last.


Any tips?
