After patching the bitwise 0x04 comparison, the controller can finally be detected, but is unable to find any devices (tested against a Wiimote and an Android phone). This is the hcidump -X: https://gist.github.com/mixedCase/d6962b3d24e13cf4443e8193c1451c5d These are the relevant dmesg lines: [ 50.227320] Bluetooth: hci0: CSR: New controller detected; bcdDevice=0x2520, HCI manufacturer=10, HCI rev=0x3120, LMP subver=0x22bb [ 50.227330] Bluetooth: hci0: CSR: Modern CSR controller type detected [ 50.251489] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 50.251490] Bluetooth: BNEP filters: protocol multicast [ 50.251493] Bluetooth: BNEP socket layer initialized [ 50.340205] NET: Registered protocol family 38 [ 50.362740] Bluetooth: RFCOMM TTY layer initialized [ 50.362745] Bluetooth: RFCOMM socket layer initialized [ 50.362756] Bluetooth: RFCOMM ver 1.11 After trying to find devices with Blueman: [ 107.543868] Bluetooth: hci0: command 0x2005 tx timeout [ 109.677220] Bluetooth: hci0: command 0x200b tx timeout [ 111.810719] Bluetooth: hci0: command 0x200c tx timeout --- After patching out both comparisons, the hcidump -X changes a little bit: https://gist.github.com/mixedCase/e286bbc5f43807bd04c59c2c75cfb88f I notice in there my machine's hostname (Enterprise) which is the default bluez identifier. Thanks for all the help so far! Hope we can find a pattern here. -- You are receiving this mail because: You are the assignee for the bug.
