Eventhough with Ubuntu’s Feisty Fawn release I plugged in the BT Dongle and the mouse and keyboard was working right away; even the main multimedia keys. But still there are some problems like a “sleeping” mouse pointer every now and than, some mouse buttons, e.g. the thumb ones, don’t work as intended.
Update 2008/07/14: There seam to be possibilities to even get the LCD of DiNovo’s keypad working. So far I haven’t found a way to auto synchronize it as it does with Logitechs Windows driver.
