And then there is Wireshark in Windows, with libpcap for USB... It can easily decode and record all USB frames. I successfully used it some time ago to debug a custom made USB board and found bugs in the firmware, which I had access to that way. In the end, there was a bug in the interrupt handler: a race condition overwriting the USB communication buffer too early and thus sending back wrong data in the USB HID frames back to the PC (part old data, part new data). The bug was uncovered by our implementation using a highly optimized threaded implementation to use the maximum bandwidth the device could provide. It wasn't possible to convince the firmware programmer about the bug (which was really expensive for our customer) and the project was eventually stopped. Strangely, they later provided a firmware without this failing behavior, much later. Project still paused. But the preliminary implementation now runs and show very high time resolution of measurement data (it's an electrochemical spectrometer, just if you're curious). Just that in Linux tools are available more easily doesn't mean that Windows is more "secure". ;-) Choose your partners wisely. -- Regards, Kai Replies to list-only preferred.
