I have problems receiving data at ep0 out. I'm using the TWR-K21D50M board as usb device.
The CDC-example works fine and i managed it to customize it for my needs.
I have a programm which sends data on ep0 out to the device and i can receive it, but if the data is 0xFFFFFFFF or 0xF5F5F5F5, there is a timeout error and i dont get the data.
I dont know why i can't get this data.
The SIE could have problems to receive many "ones" in the data section.
I hope anyone can help me to manage this problem.
