Xen: Can USB device be passed through to Linux DomU?

[Mayuresh <mayuresh%acm.org@localhost>]

I have a Huawei EC156 modem which does not have a driver on NetBSD, but
has one on Linux.

Will it be possible to pass the USB device through to Linux DomU to use
the 3G modem on DomU?

I run NetBSD 6.1 i386 XEN3PAE_DOM0 with stock config from
/usr/src/sys/arch/i386/compile/XEN3PAE_DOM0

I have xenkernel41-4.1.6.1nb10 and xentools41-4.1.6.1nb4

Mayuresh.
