hid2hci in udev rule not working

hid2hci in udev rule not working

[Nicolò Chieffo]

Hello, I own a laptop with a bluetooth which is automatically detected
as a HID device if I switch it on when ubuntu is running.
in lsusb I see those 2 lines, for HID mouse and keyboard

Bus 003 Device 010: ID 413c:8158 Dell Computer Corp.
Bus 003 Device 009: ID 413c:8157 Dell Computer Corp.

the package bluez 4.32 which I have installed from Jaunty, includes
the file /lib/udev/rules.d/62-bluez-hid2hci.rules with the content:
ACTION=="add", ATTRS{idVendor}=="413c",
ATTRS{bInterfaceProtocol}=="02", ATTRS{bmAttributes}=="e0",
RUN+="/usr/sbin/hid2hci --tohci"

unfortunately when I enable the bluetooth switch, the udev rule is not
called. in my dmesg I see:
[ 1090.952069] usb 3-1: new full speed USB device using uhci_hcd and address 15

This rule actually was denied upstream so it's carried as an Ubuntu
patch.  Upstream prefers that hid2hci be modified to take command line
arguments before accepting this type of patch.

It looks like for some reason or another the rule doesn't work with
newer udev versions.  Can you try the attached rule instead?  If that
works out, we can at least put that together as an Ubuntu SRU until the
device arguments get added to hid2hci.

#UDEV Rules to match on Bluetooth USB dongles that need to be switched to HCI mode upon
#being plugged into the PC's USB bus.

#This rule covers a variety of Dell Bluetooth adapters
# it looks like a bit of an odd rule, because it is matching
# on a mouse device that is self powered, but that is where
# a HID report needs to be sent to switch modes.

It works! Thank you very much. You can push the new version in jaunty.
