Thanks for all your suggestions first. USB Monitor seems to fit my needs quite well, though I've been running the device only on a 2.0 port today. Either there's no support for USB 3.0 yet or I was unable to spot it (but I can test my case with USB 2.0 as well).
I've also tried USB 2.0 ports, to no avail. Nevertheless, it was good that Xiaofan mentioned the firmware update, as I haven't been aware that this is necessary as well (the Wiki pages just warns that the driver has to be updated). I run Windows 7, so I'm stuck with the Renesas/NEC driver. After tracing the communication with the original application, I must admit that I've been a bit naive about how the firmware is downloaded. It's not a consecutive stream of bytes in the first place, but chunks starting at different addresses. So the stall is plausible. I have to rework my code accordingly and will let you know if I have something working. Thanks for your help so far. Even though it might not have solved the problem, I'm aware of quite some pitfalls now one can step into. All the best, /Markus ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
