You sound a little confused (okay, the architecture is not exactly well documented). HCI is the low-level bluetooth device. I wouldn't say it's even a protocol. It's rather the hardware interface. It controls the immediate BT hardware stuff. The hcitool can issue most HCI commands to such a device. Bluetooth supports several transport layers: UART, RS232 and USB. For us only USB is relevant. See hciconfig. HID is a USB device class and as such a Bluetooth "profile". All mice and keyboards use that. hid2hci is only used for dongles. Some Logitec mice for instance come with a cradle.The cradle is connected to an USB port in your PC and has a bluetooth device built-in. Or you may have a Bluetooth USB stick, because your laptop comes with no Bluetooth onboard. Both are dongles. The mouse so speaks with the dongle only. In such a setup the dongle by default acts as a (USB) HID device: i.e. it transparently forwards the mouse data as if the mouse was directly connected to the USB port. If in such a setup you want to configure the pairing for instance, you must switch the dongle to HCI mode. So the OS sees the Bluetooth device (connected over USB). That's what hid2hci is for. Nothing else. In my case, I don't have a dongle. > See first mail. Did not work. For logitech devices there are some special > commands, maybe we need some for Apple too?!

Of course. There is no other possibility. You may want to check the data that your mouse sends with hcidump, as I have demonstrated on my aforementioned site. If you can see the scroll events, then your BT setup is correct. Next step is to fix the mapping the depths of the kernel and Xorg.... My rough guess is that the Xorg drivers screw it up. > Regards > Sven > Cheers Odi ------------------------------------------------------------------------- Take Surveys. Earn Cash.
