http://askubuntu.com – i have a "generous" wireless mouse, it was working perfectly on windows, but not on Ubuntu, it doesn't work at all. i changed it's Usb thingy into different Usb ports, but still it didn't work, it is not even listed as things that are on Usb ports, what should i do to make it work? is it even possible for it to work? please help me, thanks Generous, 2.4GHZ WIRELSS OPTICAL MOUSE, Rating: 5V, 100mA, RF748, that's all the info i could find, is it of any help?
