So am I! It's been a while since I've done any work on it, but that's mainly because those tools I've made work just fine now: https://github.com/trygvis/javax-usb-libusb1 > What is the most easiest way to test bulk transfers?

While I got some of it to run and pass I ended up with error that might have been right, but I couldn't figure out which values it actually required. I started on a small tool that I use to run the new test I've ported, but it's not very much maintained either. -- Trygve ------------------------------------------------------------------------------ The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.
