Add note on FTDI permissions
A common failure of labRemote with the FTDI dongles is due to permission issues. The following udev rule needs to be added for users to be able to open the FTDI device.
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6014", MODE:="0666", GROUP:="plugdev"
We should do the following:
-
Raise errors when unable to open a device (ie: ftdi_list
currently silently prints empty strings when it cannot open device). -
Add a FTDI FAQ page that outlines common problems, including the permission issue outlined here.
