[pyusb-users] Permission problem with recent Ubuntu release and pyusb ?

[Romain A. <r.a...@gm...>]

Hi everybody, Hi Wander,

After updating my OS a strange thing happened to my Udev rule.

SUBSYSTEM=="usb", ATTR{idVendor}=="10c4", ATTR{idProduct}=="0002", MODE:="0666"

Doesn't work any more, pyusb complain about a permission problem.

I had to do a trick and add a "GROUP" key to the rule and add my user
to this group:

SUBSYSTEM=="usb", ATTR{idVendor}=="10c4", ATTR{idProduct}=="0002",
MODE:="0666", GROUP:="usbusers"

Any idea what happened ? Is the problem related to udev or ubuntu ? I
googled a lot but I can't find an answer.
