I am working with libant and pyusb to support Ant+ devices. The issue I am trying to fix is preventing access to a device that is already open by another process. There may (usually will) be multiple Ant+ devices plugged in, and one or more may be in active use by another program.
I need to find an unused device and then open that, without interfering with the use of the other open devices. Currently, I'm testing on Linux, but this will be deployed on Windows and macOS as well. There doesn't appear to be anything to prevent multiple access, and at least initial testing with two processes both using pyusb shows them interfering with each other as they open, close while attempting to access the Ant device. Suggestions would be appreciated.
