…FS devices With the commit fe3c001 ("usb: device_next: disable high-speed USB device descriptor if not used") there is no high-speed device descriptor by default. Signed-off-by: Johann Fischer <[email protected]> (cherry picked from commit 569f4d6)
In both implementation, when comparing received data length take into account that the buffer obtained from bt_buf_get_tx() stores the type at the top. The buffer types are H:4 and in the TX path we need to check for BT_HCI_H4_* types not BT_BUF_*. In the legacy implementation, the hci_acl_pkt_len() function obtains the length from the USB transaction buffer, which does not contain a buffer type at the top. In the new implementation, partially revert the changes and restore hci_pkt_get_len(), this will be required for any further changes anyway. Fixes commit f85d63a ("Bluetooth: Remove USB H4 mode support"). Signed-off-by: Johann Fischer <[email protected]> (cherry picked from commit 96422f2)
…nsfer enqueue fail Do not take semaphore if transfer enqueue fails. Signed-off-by: Johann Fischer <[email protected]> (cherry picked from commit d2e42c9)
…ng descriptor The intention was to use the "interface-name" string property in the interface string descriptor, but using the label property is acceptable again. Therefore, allow the use of the DT label property string in the interface string descriptor. Follow exactly the same approach as in the CDC ACM implementation introduced in the commit b079140 ("usb: device_next: cdc_acm: allow setting the interface description"). Signed-off-by: Johann Fischer <[email protected]> (cherry picked from commit 79a8073)
