Dear all

we use cy7c68013a chip in our project. it operates well in high speed mode but when we config it in full speed mode and read endpoint 0x86 it returns PID STALL error.

after power on reset the SetupCommand function invoke EZUSB_STALL_EP0() because of receiving 00000000.

could any help us how to solve it?

best regards.

Have you added full speed USB descriptors? Is the device enumerating fine? How is the 0x86 endpoint configured? Which type? What Max packet Size?

Hi,

Make sure you added correct full speed descriptors.
