Do someone have an example, how to implement this ? I was searching the half day, but I cant see where to start. Is this done with another report descriptor or is there more ? Until now this is my (not all, borrowed some) code: ... stuff char usbHidReportDescriptor[73] = { 0x05, 0x01, // USAGE_...

But my last thouth is: It could be posible to drive the avr with 18Mhz or 24Mhz. ( I know it would be outside Spec ) But s...

I tried: uchar usbFunctionWrite(uchar *data, uchar len) { return 1; } and in the main: int main(void) { for(;;){ usbPoll(); } return 0; } which should result in fastest transfer. But it dont goes over the 5kByte/s transfer speed limit. I ...
