My serial port USB cable is still not in use because I have not found a way to address anything connected with this cable. Right now I have the serial connector from my camera connected to this USB cable. I am running both 10.1 and 9.3 fully up to date. The camera should be recognized if used on a normal serial port but via the USB port it does not work. The cable is recognized as /dev/sde1 and can be found in the fstab. Mounting results in following: # mount /media/imation mount: /dev/sde1 is not a valid block device In my fstab it says for this device: /dev/sde1 /media/imation vfat rw,noauto,users lsusb tells me following: # lsusb Bus 001 Device 006: ID 15ca:00c3 Bus 001 Device 005: ID 067b:2303 Prolific Technology, Inc.
