Chris, with CYGDAT_IO_USB_SLAVE_CLASS_TYPE == "ACM", lsusb looks better (but
scroll down for the problem):

usb_start() and usbs_serial_wait_until_configured() are required before calling
usbs_get_[rt]x_endpoint() so the sequence of calls in usbs_serial_start()
needed re-ordering. 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. Any ideas?
