Phidget Rapidly Connecting and Disconnecting

Posted: Mon Oct 29, 2018 6:43 pm
by djcruz
Hello, I've been practicing with the python API for a project for my work. I've encountered a strange issue I've been trying to solve for the past couple of days. Randomly when I open the channel for a phidget from software it acts as if the phidget is rapidly connecting and disconnecting. Once it occurs this persists across multiple programs and the only way to stop it is to either physically detach the phidget from the computer or reset the USB port it is connected to. I've tried different USB ports on my computer, different USB cables, and different phidgets. In all cases the error has had a chance of happening. In case it is something to do with my practice code, I'll post that here, although I pretty much just copy and pasted the manager and voltage ratio code. I'm using the interfaceKit 8/8/8 on an ubuntu 18.04 system. I've also tried logging the program, which I will also attach. It seems to be a problem with reading from the USB but I could be wrong. I'll also attach an example of the output I'm getting. Any input would be greatly appreciated, this board would go well with the project I'm currently working on.

Are you able to try a different computer - preferably with a different motherboard/USB controller? You could also try adding a powered hub in front of the Phidget. Errors like this usually indicate hardware or power issues.

Thank you for the quick response, I'll try it out on different systems and report back.

Just a quick update on my issue, I tried switching to different USB ports before which made no difference. I noticed yesterday that the USB ports I tried are all connected to the same USB controller on the desktop. Switched to a completely different one and I've yet to see the problem occur again. Thank you!
