Hello

First of all, I wrote that the device is working with windows, but the 
part I omitted is - windows is running in qemu on the same machine, 
where I'm testing the linux-gpib.

I can't show you the syslog output, because I have now installed the 
closed source driver and appropriate software from National Instruments 
(which I don't want to use in the end, but I use it now as a sanity 
check only).

The lsusb output is:
$ lsusb -d 3923: -v
