I cannot speak for Bluetooth mice, but I tried a USB mouse via a powered hub on my N770 running the latest production OS2006. In fact, on the hub I had: A USB to PS/2 keyboard+mouse adapter, with both mouse and keyboard in place. A USB to RS-232 adapter with a GPS on it (through a serial monitor box with LEDs on the various data lines) A USB mouse (in addition to the PS/2 mouse) I had previously modified the /etc/init.d/x-server.sh file to tell the X server to look at /dev/input/mice Here were my results: Mouse: Not working. dmesg shows the mouse as detected, the mice show up in /sys/bus/usb/devices, but lsof shows that Xomap did NOT open the /dev/input/mice file. (checking the /proc/<pid of Xomap>/cmdline shows that the command line was indeed modified). cat'ing /dev/input/mice did not yield any data when the mouse was moved. Keyboard - worked. Having the Bluetooth keyboard plugin was helpful as it turned off the virtual keyboard when the external keyboard was activated. GPS: Didn't work. I was unable to get MaemoMapper to indicate GPS lock, after having set the GPS device to /dev/ttyUSB0. I had modified the permissions on the serial devices to be world readable. and I was able to verify that when Maemomapper opened the device RTS was asserted. I was able to verify that the GPS was sending data, but the data was not received by Maemomapper. cat'ing the serial device yielded no data. dmesg showed several input overrun messages from the serial device.
