I found that btusb.enable_autosuspend=3Dn seems to solve the problem. Commit 67dba2c28fe0 ("btmtk: Fix failed to send func ctrl for MediaTek devices.") prevents the device from suspending during btmtk_usb_shutdown() = to avoid timeout errors similar to the ones I'm experiencing: btmtk_usb_hci_wmt_sync() hci0: Execution of wmt command timed out btmtk_usb_shutdown() hci0: Failed to send wmt func ctrl (-110) So I wonder if the same thing is happening during btmtk_usb_setup(). There's a long gap until the bluetooth driver is loaded. This computer has = an external USB-C dock that sometimes takes a long time to initialize, also the hard drive is encrypted with LUKS so the btusb driver (and its firmware) ca= nnot be loaded until I enter the password and the rootfs is decrypted. All this = can take easily 20 seconds. So maybe the bluetooth adapter suspends before the driver is loaded and tha= t's why the initialization fails, does that make sense? I tried patching btmtk_usb_setup() with the same approach and so far I have= n't been able to reproduce the issue anymore. --=20 You may reply to this email to add a comment.
