I have a USB to serial converter attached to my box.
if I login to the box and send/receive serial commands over this unit
it works without error EVERY time.
however, if I run the same command set from with-in the extensions.conf
with System() I get errors in dmesg like "pl2303 ttyUSB0: pl2303_open -
failed submitting read urb, error -22"

PATH or other environment variables?
Does
sudo env --ignore /home/silentm/bin/usbserial -start
yield any clues?
