usb device mapping by device interface

[dhiaeddine]

hi,
I'm sharing a Quad rs232-HS usb composite device, to 2 windows2012r2 VMs
device is only usable on only one VM
is there a way to let it be used by both VMs simultaneously?
or is there a way to share the device by device interface so to map if 0 and if 1 to VM1 and if 2, if 3 to VM2 ?
now mapping is made with "usb0: host=3-8" on both VMs
