The part arrived today and after a few minutes of hacking, it works
beautifully. I didn't have to install or configure anything for
/dev/ttyUSB0 to appear. And now I have a very simple python script that
can turn the relay on:
f=open("/dev/ttyUSB0","wb")
for byte in [0xff, 0x01, 0x00]:
f.write(chr(byte))
f.close()
(Is there a one-liner to do this?)
I wired the relay such that when the USB connection is lost, the power
stays on. It works wonderfully.
Thanks for the help all.
