This page describes all changes made to the usbd_cd_raw package, USBD Raw Class Driver, since its release.
Note: This package was previously named usbd_cd_bulk.
Version
4.1 (2021-02-25, 11:00):
- skip_zlp parameter had not been used by the USB stack in the receiving direction (usbd_raw_read() and usbd_raw_read_int()), so it removed it from these two API functions. The reason is that it is not possible to consider the need of a Zero Length Packet on the device side; the user must configure the host side application and the device side application in sync with each other instead. (That is, the host shall send data to the device from a buffer having the same size as the buffer the device receives the data into.)
3.2 (2020-01-15, 13:53):
- Compiler warning eliminated.
3.1r3 (2019-07-25, 12:47):
- The actual interface number is used for the usb_claim_interface() function in the libusb-bulk util program.
