Hi Ian,
Not sure why the error message is that one in particular if the problem
is due to permissions (maybe an old bug in 0.19?). Anyway, to allow
normal user access to USB devices, you need to add udev rules. If you
find out where your rules are stored (mine are in /lib/udev/rules.d),
add a file called 99-mspdebug.rules, containing these lines:
ATTRS{idVendor}=="0451", ATTRS{idProduct}=="f430", MODE="0660", GROUP="plugdev"
ATTRS{idVendor}=="0451", ATTRS{idProduct}=="f432", MODE="0660", GROUP="plugdev"
ATTRS{idVendor}=="2047", ATTRS{idProduct}=="0200", MODE="0660", GROUP="plugdev"
ATTRS{idVendor}=="2047", ATTRS{idProduct}=="0010", MODE="0660", GROUP="plugdev"
ATTRS{idVendor}=="2047", ATTRS{idProduct}=="0013", MODE="0660", GROUP="plugdev"
Then:
* run: udevadm control --reload-rules
* add yourself to the plugdev group
* log out and in again
* replug your device
Hopefully you should then be able to use the device as a normal user.
You might need to pick a different group if you don't have a "plugdev"
group -- it doesn't really matter.
Cheers,
Daniel
