[Spice-devel] usbredir doesn't work

[javaon]

I tried a USB thumb drive, it can be redirected successfully. The device (SanDisk) is marked in blue below.

# lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 007: ID 0781:5567 SanDisk Corp. Cruzer Blade
Bus 001 Device 004: ID 0a5c:217f Broadcom Corp. Bluetooth Controller
Bus 001 Device 005: ID 04f2:b221 Chicony Electronics Co., Ltd integrated camera
Bus 002 Device 003: ID 17ef:1003 Lenovo Integrated Smart Card Reader
Bus 002 Device 004: ID 1483:c007

The device failed to be redirected (ID 1483:c007) is in red above. This device is USB key containing a bank certificate. But it's can be attached as a device to guest on my host machine.

And attached is the output of "lsusb -v"

Thanks,
