Hi everyone,

I am using LPC11U68 microcontroller and I have problem with USB communication. When I try to send from LPC11U68 to PC I have problem with messages larger than 64 bytes. Everything works fine with smaller messages. Does anyone have something similar with USB peripheral on this LPC device?

Regards, IVan M.

Thank you for your answer. I use BULK transfers. I realized that I must separate large packets, to 64 byte sized,  cause my code don't do that, at this moment, and that is a problem.

You don't say what type of end point you are using, but most likely you are using an endpoint limited to 64 bytes... See http://www.beyondlogic.org/usbnutshell/usb4.shtml
