I'm now getting an assertion failure due to invalid endpoint in stm32_usb_get_txep() and it looks like the TX endpoint map is not correct: (gdb) print txep_map $8 = {0x0, 0x0, 0x68024ae0, 0x0 <repeats 12 times>} stm32_usb_get_txep() is looking up logical endpoint 1 (TX) and therefore retrieving element 0 which is 0x0.
