Description:	Use a bluetooth-keyboard only for all tasks (without the need of an additional keyboard connected via cable while in BIOS or boot-manager) OS: SUSE Linux 9.2 32bit software: bluez-libs-2.10-2 bluez-utils-2.10-15 (kdebluetooth-0.0.cvs20050131-5) Bluetooth-Adaptor: D-Link DBT-120 (USB) If the DBT-120 is at least Rev. 2, you can update the firmware on it (using an Apple-Computer). This allows you to use the Apple Wireless Keyboard already at boot-time bevor any bluetooth-stack is loaded. On power-up it will work as a HID-proxy. That means it will establish the connection to the Apple Wireless Keyboard (and should do with a bluetooth-mouse as well, but I haven't tested that) without pairing and present it to the System as an ordinary USB-keyboard (or USB-mouse). In this mode you can already use your Apple Wireless Keyboard with every OS that supports USB-keyboards. If you want to use the DBT-120 to connect other bluetooth-devices as well, you need to switch it from HID- to HCI-mode. Under Linux use: hid2hci --tohci That has to be done once every time you boot linux. (Under Windows I used a tool call hidtohci.exe, available from another bluetooth-keyboard-manufacturer. Worked fine with my hardware. I don't remember where I found it, just google for it) The very first time you do that, you need to pair the DBT-120 and the Apple Wireless Keyboard. I don't remember exactly what I did to accomplish that (have a look at the documentation that comes with bluez.utils, especially at README.keyboard mouse), but it was tricky, because i had to blindly hack the PIN after I first connected the Apple Wireless Keyboard with hidd -c If you wait to long (some seconds), the pairing might fail. If that all works, make sure you have configured the hci-daemon (hcid) to become master on incoming connections. (The Apple Wireless Keyboard falls in sleep mode if you don't use it for a while. A single press of a key wakes it up and lets it try to reconnect to the DBT-120. That will fail without forcing hcid to switch to master) For that my /etc/bluetooth/hcid.conf looks contains the following line: lm master; I'm not sure, which of the following lines are critical for the Apple Wireless Keyboard to work properly. Start with the defaults and change one by one until everything works: autoinit yes; security auto; pairing multi; class 0x100100; iscan enable; pscan enable; lp rswitch,hold,sniff,park; auth disable; encrypt disable; I bought my bt-hardware in July 2004 and I'm not sure if it works with your gear. The Updater can be found here: http://www.apple.com/support/downloa...updater12.html This is a description of the update: http://docs.info.apple.com/article.html?artnum=86493 (Apple claims that the DBT-120 will get incompatible with non-Macs afterwards. This is WRONG. But you need to switch it from HID- to HCI-mode as mentioned bevor.)

Excellent information, than you very much!

If someone could confirm dbt-120 compatibility in hci-mode with Logitech's V270 mouse, I'd be grateful. Allso information of flashing without mac would be appreciated.
