Hi,
Cleware GMBH is a German company producing all kinds of USB devices.
Switches, lights, sensors, etc.
As a hobbyist, I do the Linux support for them (I wrote a userspace
program to control their devices).
Now a new range of products are to be released with new firmware. I
think I'm seeing problems with them and I would like to discuss them
here before bothering Cleware.
When the device is plugged in, I can access it, somewhat. Why somewhat?
Because it looks as if it is "thrown out" and reconnected each 6-7
seconds:

My question now is: is this a Linux kernel problem? Or a problem with
the firmware of these devices? If it is the latter case, please (please)
tell me (if possible) what it is doing wrong.
This was tested with kernel 3.10 and 3.11-rc4.
The device is connected directly to the laptop (one of those fancy
alienwares).
libusb -v tells me:
