I'm using a Phidget VINT Hub and a REL1100_0 isolated solid state relay to drive some 5V LED's. To power the LED's (because the relays need external circuit for power), I used the Red+Black wires from a Phidget cable attached to my VINT Hub (Red wire --> LED+ | LED- --> relay port | relay GND --> Bl...

Edit:

My script runs correctly the first time, but if it crashes once, the channels on one Phidget will get stuck on ch.openWaitForAttachment(), and hang forever or time out. Could this be because I'm not closing ...

I am playing with two 8/8/8 Phidgets, using the Python API on Ubuntu. On MacOS I have no problem, but on Linux this comes up. My script works right the first time, but after I close it or kill it a few times I lose the ability to open channels. I believe I am closing all of my ports properly, but it...
