As others may run into this in the future I want to to document what is needed to use CC-USB/VM-USB on Ubuntu 7.10 (gutsy gibbon).

It appears the these systems have set permissions restrictions on driver access as well as device special file access. You will need to do the following to make the USB device special files visible and make non-root software able to use them:

In /etc/fstab add:

usbfs /proc/bus/usb usbfs defaults,devmode=0666,busmode=0777,listmode=0666 0 2


In /etc/udev/udevs.d/40-permissions.rules

Locate the line with

SUBSYSTEM=="usb_device", ...

Change this line to read:

SUBSYSTEM=="usb_device", MODE="0666"

Reboot the system. I am not sure if the wienerusbd is even necessary after these changes. ... but I run it out of habit. Wink
