12 years ago --- Quote Start --- I'm running windows. and the byte blaster pops up with the proper name (NAI USB DEbugger is what we programmed it as). --- Quote End --- Ok, so it sounds like it is enumerating Ok. If you download USBView (a free microsoft tool) you could read all of the descriptors and confirm they match what you expect. --- Quote Start --- I did not see any lights while initializing though. and currently we have only more unprogrammer boards. no working usb blaster II's --- Quote End --- I'd recommend buying the cheapest development kit you can that contains the USB-Blaster II circuit. At least then you will have a known-good board to compare transactions to. I'd also recommend buying a USB logic analyzer; Total Phase and LeCroy sell them. You could then trace the USB initialization phases and traffic. If you can only afford one of these, then go for the development kit, and use Wireshark under Linux to trace the USB traffic (Windows Wireshark does not support tracing USB traffic). You can then compare your board's traffic to the known-good development kit and see where they differ. Cheers, Dave
