Windows (all?) guests cannot access USB devices due to lacking group-write permission on device

Description

Howdy,

I noticed my Guest (Windows 7) was no longer able to access the USB devices on my Host. I'm not sure when this regression occurred because it's not a frequent activity.

I checked the permissions in /dev/bus/usb' for group vboxusers' and found all the devices didn't have write' permission. Once I manually chmod g+w' the devices, the Guest gained access.

I confirmed that 10-vboxdrv.rules' is in /etc/udev/rules.d' ...

Please let me know if other information is required.

I'm heading out on vacation this Friday for a week ... just a heads up. :)

Thx a lot!

Can you try renaming 10-vboxdrv.rules to start with a 50? This is needed on some (especially SUSE) systems.

Hi Michael,

Renaming 10* to 50* did the trick - see below.

And you're correct, my host O/S is `openSUSE' .... I should have mentioned it. Sorry.

Thank you for the quick turn-around. I'll manually change my VM's.
