I've just installed this version.

Here's what I see so far :

The driver inserts well and when I connect my device it shows /dev/usbtmc0
with major 180 and minor 176.
It only creates one device (Stefan's driver created two) but I'm not sure if
that has changed for a reason so just let you know.

When I disconnect my device, usbtmc0 will not be destroyed. After connecting
the device a couple of times I have a lot of /dev/usbtmc.. files.

I would expect the following to work :
echo :*IDN?>/dev/usbtmc0
But it returns : No such device

Using echo and cat to test the device is quite convenient, but is this
supposed to work yet ?

I checked /sys a bit and found that the endpoints are correctly found.

I also had an issue applying the patch (documentation and makefile). Not sure
if that's related to my system though, I'll check that later.

regards,
Marcel
