Android USB Accessory Multi Thread

Question

Headache caused by multi-threading and Android Open Accessory.

I need to communicate with a USB Accessory, but I need to do it from 2 threads.

Answer 1

If using multiple threads, I do run into I/O Error (No such device) sooner or later, because I will have a collision between read & write being executed at the same time.

This says it all. Since you are doing read and write on the same channel that does not support concurrent access, you are required to have your thread wait until the other thread is done doing read/write.

Your two-thread approach is what I would do, more or less. Good luck and trust in yourself.
