[Bug 658471] Re: udev fails to call hid2hci for Logitech USB Bluetooth adapter

[JasonPorter]

Additional info:

With default Natty configuration in /lib/udev/rules.d/70-hid2hci.rules,
I get the following three devices reported by lsusb:

Bus 005 Device 025: ID 046d:c71c Logitech, Inc. 
Bus 005 Device 024: ID 046d:c71b Logitech, Inc. 
Bus 005 Device 023: ID 046d:0b06 Logitech, Inc. 


After the change suggested by this bug report, I get all three of those devices plus an additional device that did not appear before at all:

Bus 005 Device 026: ID 046d:c709 Logitech, Inc. BT Mini-Receiver (HCI mode)
Bus 005 Device 025: ID 046d:c71c Logitech, Inc. 
Bus 005 Device 024: ID 046d:c71b Logitech, Inc. 
Bus 005 Device 023: ID 046d:0b06 Logitech, Inc. 


It seems it's not just the mode that changes for the existing devices, but also involves the detection of additional hardware.  I hope my suggestion about the Additional Drivers function in the previous comment is something that might have some appeal... it would preserve default "plug and play" functionality while allowing a clear and direct upgrade/configuration path to connect the devices properly via Bluetooth.  This problem has been one of the top generators of "Logitech" related bugs in Ubuntu since 8.04, that's over seven major revisions of the OS, and I'm sure the devs are tired of seeing it crop up repeatedly.

Title:
  udev fails to call hid2hci for Logitech USB Bluetooth adapter

Status in “udev” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: udev

  This bug is related to Bug #444420, but I was told to file it as a new
  bug here.

  Here are the rules I have for Logitech USB Bluetooth dongles in
  /lib/udev/rules.d/70-hid2hci.rules:

  # Logitech devices
  KERNEL=="hiddev*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[35e]", \
    RUN+="hid2hci --method=logitech-hid --devpath=%p"
  KERNEL=="hidraw*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[4abc]|c71[34bc]", \
    RUN+="hid2hci --method=logitech-hid --devpath=%p"

  This is an upgrade from Lucid (on which hid2hci was called) to
  Maverick (at which point, hid2hci was no longer called).

  As seen in lsusb output, my adapter should have matched the second
  line:

  Bus 001 Device 006: ID 046d:c70c Logitech, Inc. BT Mini-Receiver (HID proxy mode)
  Bus 001 Device 005: ID 046d:c70b Logitech, Inc. BT Mini-Receiver (HID proxy mode)
  Bus 001 Device 003: ID 046d:0b02 Logitech, Inc. BT Mini-Receiver (HID proxy mode)

  I removed the KERNEL condition from the rules file:

  # Logitech devices
  ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[35e]", \
    RUN+="hid2hci --method=logitech-hid --devpath=%p"
  ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[4abc]|c71[34bc]", \
    RUN+="hid2hci --method=logitech-hid --devpath=%p"

  I restarted udev and re-inserted the adapter.  While everything seems
  to work correctly now, I am told that this is wrong because it could
  somehow overmatch something.

  Attached is the output of `udevadm monitor` when udev is running with
  the original Maverick 70-hid2hci.rules file and the adapter is
  inserted.
