When I JVisualVM profile my USB application, reading the USB device is eating
up a whole thread – is there no way to make this asynchronous (or yield the
thread until data is available) and save CPU cycles?
My device is running at about 170Hz and that means about 7 milliseconds wait
per report acquisition. That's too low for me to be able to do anything
sensible with Thread.sleep, but high enough that it's eating 93% of that
thread's time.
Strategies to save cycles would be greatly appreciated.
