I'm getting the same error messages but also silent failures. Having Bluetooth scan enabled it will detect devices correctly for 30-120s, then it will keep discovering fewer and fewer devices to a point at which it can not see any bluetooth devices anymore. Then, after some more time it might start reporting "Bluetooth: hci0 *somethingsomething* command failed"
The only workaround is to: modprobe -r btusb modprobe btusb I'm forced to do it every minute or so when it becomes flaky. distro: Antergos Linux (Archlinux clone) uname-a: Linux default 4.12.12-1-ARCH #1 SMP PREEMPT Sun Sep 10 09:41:14 CEST 2017 x86_64 GNU/Linux lspci: Network controller: Intel Corporation Wireless 3165 (rev 91) relevant logs: [ 5.308899] Bluetooth: hci0: read Intel version: 370810011003110e00 [ 5.311044] Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-hw-37.8.10-fw-1.10.3.11.e.bseq [39629.337875] Bluetooth: hci0: read Intel version: 370810011003110e25 [39629.337879] Bluetooth: hci0: Intel device is already patched. patch num: 25 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1591167 Title: Bluetooth: hci0 link tx timeout with Intel Corporation Wireless 7260 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1591167/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
