I have an issue with the USB timing out that I have narrowed down to something with the Beagle Bone, possible the USB drivers on the kernel? I have tested the all the libraries, python version, etc. in an identical virtual environment on my PC, everything works fine. 90% of code works on the BeagleBone, only select parts where I am sending a specfic command through the USB does this problem occur. I did some digging and it looks like something similar to what was happening a few years ago on of the earlier kernels. I have tried many of the older and newer kernels am currently running Kernel 4.9.36-ti-r45. All the kernels I have tested still had this problem. Below is the log:
