Before I tried what you suggested below, I had a look at file structure in /sys. The tree looks like this: /sys/bus/usb-serial/drivers/ with subdirectories there as follows: edgeport_2/ edgeport_4/ edgeport_8/ epic/ generic/ There is no sign of io_edgeport/ (which would be required in your suggestion below). Do you want me to create this directory before adding the new_id file within it? Also, although the permissions for /sys/bus/usb-serial/drivers/ would appear to permit writing by root, I am not allowed to write in this directory (or anywhere else in the /sys tree. What's the trick? Thanks. doug.
