https://bugzilla.kernel.org/show_bug.cgi?id=60824 --- Comment #30 from raestloz@xxxxxxxxxx --- Well, I tried to build a custom kernel (4.19.55) with my bcdDevice and LMP subversion included in the btusb.c file. btmon shows promise, hcitool dev actually shows a device, but dmesg | grep tooth reveals that I'm stuck at HCI_OP_READ_LOCAL_VERSION, apparently it times out, reading hci0: command 0x1001 tx timeout and CSR: Local version failed (-110) -- You are receiving this mail because: You are the assignee for the bug.
