This approach differs from the current method used in the Bluetooth upstream driver, which utilizes existing bulk endpoints. The interrupt endpoint provides guaranteed bandwidth, sufficient maximum data length for ISO packets and error checking. Certain new functions related to USB transportation, such as urb allocation and submission, are implemented in btusb.c to leverage existing functions and data structures defined therein. Meanwhile, vendor-specific functions unrelated to transportation have been moved to btmtk.c to streamline btusb.c.
