The dongle used: Bus 001 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) It works fine under Windows and kernel 6.11.1 I have to copy the following files from 6.11.1 and rebuild the kernel to make the dongle work with 6.11.2 drivers/bluetooth/btusb.c include/net/bluetooth/hci_core.h net/bluetooth/hci_conn.c net/bluetooth/hci_sync.c net/bluetooth/mgmt.c Theses files were changed from the following commits between 6.11.1 and 6.11.2 5 days Bluetooth: btusb: Fix not handling ZPL/short-transfer Luiz Augusto von Dentz 1 -1/+4 [ Upstream commit 7b05933340f4490ef5b09e84d644d12484b05fdf ] Requesting transfers of the exact same size of wMaxPacketSize may result in ZPL/short-transfer since the USB stack cannot handle it as we are limiting the buffer size to be the same as wMaxPacketSize. Also, in terms of throughput this change has the same effect to interrupt endpoint as 290ba200815f "Bluetooth: Improve USB driver throughput by increasing the frame size" had for the bulk endpoint, so users of the advertisement bearer (e.g. BT Mesh) may benefit from this change.
