Hello everybody.
I’m working with microcontroller AT91SAM9260 (AT91SAM9260-EK) and trying to organize USB transmission. I have used usb-device-cdc-serial-project-1.1-iar-at91sam9260-ek (from Atmel) example (with the IAR compiler) which hasn’t worked well. The problem was that there was no data on computer although there was host confirmation during data transmission (direction MC->PC) at the size of data divisible by endpoint size (64, 128, 512 etc). Data transmission at the other size of data was OK.
I use windows usbser.sys driver (Windows XP).
I have no idea with the problem.
Thankful for any help I can get on this!
