Hi Benjamin,

Can you please help me how to do that? I install Windows in a KVM with
the mouse device as a USB-passthrough device -- shall I detach the Linux
USB driver?

No, you don't have to detach the Linux USB driver (it's done for you
by KVM IIRC).

Correct, libvirtd is the one that detaches the driver when I start the VM.

Now, shall I use hid-recorder on that device or rather usbmon while
Windows is booting?

usbmon is the tool you need. hid-recorder will not work because the
hid subsystem will be disconnected as the device is used by Windows.

You can even use wireshark now. It gives you a nice interface and
interpretation of the USB packets :)

Please see attached for the USB sniffing on the USB bus with the Crucialtec
touch pad when Windows starts up and shuts down. To drive the device, Windows
uses the Crucialtec driver according to its device settings display.

The attached log contains the log information for the mouse (device 001:005)
and the USB bridge (device 001:002). I cut out the listing for the touch pad
which is also attached to that bridge.

The strange thing, however, is the following: the mouse works in Windows when
I do not sniff on the USB bus using usbmon. But as soon as I start sniffing,
it does not work any more.

Is that log helpful?

Not really :(
I would have expected to see something like that:
XXXXXXXXXXXXXXXX XXXXXXXXXX S Co:1:XXX:0 s 21 09 0202 0002 0004 4 = XXXXXXXX
XXXXXXXXXXXXXXXX XXXXXXXXXX C Co:1:XXX:0 0 4 >

(SET_REPORT on the report ID 02 with a data length of 4)

The capture seems to confuse the windows driver and it is not
initialized correctly.

Long shot: maybe if you start the capture before attaching the device
to the Windows VM (or launching it) it will be in a better shape.

I would say that as long as the device do not work under the VM with
the capture, we are really screwed.

Cheers,
Benjamin
