I advise to Microchip, to fire such a lazy instructor.

He should check it by himself, before teaching it to others.

Or, if he couldn't really get more than 640 Kbits/s (ie. 64 bytes/frame), he doesn't realize the relation of transfer-transactions. Not qualified for an instructor of USB course.

> Do you have an example that I can use to make new test?

Realize the relation of Transfer - Transactions, first.

And then, you can write such a code by yourself immediately.

It's the first hurdle for USB beginners (and the instructor should teach it).

I've explained it on everywhere, for example,
