KVM USB Passthrough and Zydas usb wireless adapter: device or resource busy

Question

i'm tring to setup a kernel testing virtualmachine for a 80211 module.

i start my machine with this command:

kvm -m 512 -net nic -net vde -usb -usbdevice host:0ace:1215  ktesting.img

i set up a kvm image with debian connected to a vde_switch at the eth0 interface and with a

Bus 003 Device 004: ID 0ace:1215 ZyDAS ZD1211B 802.11g

i installed the 'zd1211-firmware' and give the right permissions in /dev/bus/usb.

the wlan0 interface go up:

          inet addr:192.168.2.15  Bcast:192.168.2.255  Mask:255.255.255.0

but when i try to use wpa_supplicant to connect to my router:

wpa_supplicant -i wlan0 -c conf

i got this output(stderr and stout):

i tried using the wifi adapter on my laptop to connect to the same network with the same config file installing only the zd1211-firmware and it work perfectly. it's not a problem of my compiled kernel as the problem persist with the stock debian kernel (wheezy)

There are some ports that still busy in some situations. We are suffering the same thing in usb-printers. Stay tunned in the KVM mailing list ;) — sabueso, Mar 01 '13 at 00:12
it's a bug in kvm version 1.1,i solved it with an update to the 1.3 version after a few try for reproduce it with the Debian maintainer — kurojishi, Mar 01 '13 at 10:40
