| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB protocol allows for 16 IN and 16 OUT endpoints (USB 2.0 Spec, 8.3.2.2 Endpoint Field). A function may have an EP 1 for both IN and OUT, so these two should be kept separate. As EPs are either BULK or INTERRUPT (or ISO), it is fine to have one array per direction for all transfer types (also see e236519b7365ef75c5da6a5623f0b03d9c00cfae). USB device address is 7 bits, so a bus may have more than 16 devices. Check the device number, as the DWC2 driver only supports BULK/ISO for the first 16 devices.

INTERRUPT transfers are executed in the next even/ odd microframe depending on the HCCHAR_ODDFRM flag. As there are no handshakes for INTERRUPT SSPLITs the SSPLIT may have failed (transport error) without the error being detected by the host driver. If the last CSPLIT is not received within 4 microframes after the SSPLIT there was a transaction error and the complete transaction has to be restarted.
