I based this off the usb_cdc example and just changed it to implement some control transfer handling directly. However, the host-to-device transfers start at byte 4 of the data the host sent, and then have 4 junk bytes at the end.
The bug must be in the embassy-stm32 usb_otg driver, as this example works OK on G4 (which is the plain usb driver).
