I was afraid you were going to ask me that. I run qemu via libvirt. So
I will do a bit of detective work. Here goes.
The XML for libvirt is:
--------------------------------------------------
<hostdev mode="subsystem" type="usb" managed="yes">
<source>
<vendor id="0x0718"/>
<product id="0x0637"/>
<address bus="2" device="6"/>
</source>
<alias name="hostdev0"/>
<address type="usb" bus="0" port="4"/>
</hostdev>
--------------------------------------------------
You would have to modify the vendor, product, bus, and device IDs to
suit your device.
The command (imported not wrapped, but possibly wrapped in transport)
line is:

I think the part of that mess you want is this:
--------------------------------------------------
-device usb-host,hostdevice=/dev/bus/usb/002/006,id=hostdev0,bus=usb.0,port=4
--------------------------------------------------
Where the /002/006 point to the usb device:
--------------------------------------------------
root@hawk:/etc/new.virtual# lsusb
…
Bus 002 Device 006: ID 0718:0637 Imation Corp. Nano Pro
…
root@hawk:/etc/new.virtual#
--------------------------------------------------
Check that aginst the XML above, and the vendor, product ID, bus
number and device all agree.
On the guest, the device shows up like so:
--------------------------------------------------
root@dti386:~# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0718:0637 Imation Corp. Nano Pro
Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd QEMU USB Tablet
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
root@dti386:~#
--------------------------------------------------
I suspect that the "id=hostdev0,bus=usb.0,port=4" is zero-based
(meaning the first entry is entry 0), while the lsusb listing is
one-based. But you may have to fiddle around with that anyway.
I hope that helps.
