Re: [libusb] An error on every other attempt to capture data

Tim,


I looked into the multiple threads. It is possible, but at the point I am starting and stopping things, there should only be the main thread doing any USB requests.

               The firmware developer also gave me an update with "some things that might help"...which did.  Again, thank you for the insights. It's hard developing new on both sides of the pipe and not knowing who broke what. Especially since this is my first USB project.

Is it possible you actually do have multiple threads waiting for libusb
events?
