hi

I have a strange problem when I try to send packets bigger than 1 byte to the MCU:

I get the first packet just fine, but after I stop receiving any packets.

If I use 1 byte packets I have no problem (I receive every packet the host sends)

Any ideas?

Thank's

Do you think you've provided sufficient foundational information in your question for anyone to know exactly what chip you're using, with what software and what class of USB device?
