@daib8: Thanks for the hint! I just tried it with 4.4.2 and it works great. Even with 644.

Sorry, I missed this bug report, somehow I didn't get notified by Github. I will have a look in the following days.

Regarding the "device busy" error, is currently something else on your systems accessing the device? Can you please check with `lsof | grep dev.*usb`? And interesting, according to @wdog's device...
