https://bugzilla.kernel.org/show_bug.cgi?id=103451 --- Comment #16 from Johan Hedberg <johan.hedberg@xxxxxxxxx> --- I think I know why it's not working, because of this in btusb_probe(): /* Fake CSR devices with broken commands */ if (bcdDevice <= 0x100) hdev->setup = btusb_setup_csr; Since the bcdDevice value of your adapter doesn't match that condition the btusb_setup_csr() function I modified will never get called. Let me try to create another patch. -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
