Is there anyone that can help me with this bug, please?
Here is some more information I've discoverd.
When I try to install Mythbuntu 8.04 (amd64) with the usb-adapter installed my keyborard acts wierd. First the keyboard acts normal (while the DVB-adapter is in normal state) and when the adapter starts to flood error-messages the keyboard takes aproximately 5seconds for each keypress and at some random time the keyboard flood inputs when a key is pressed (if I press "k" I get "kkkkkkkkkkkkkkkkkkkkkkkkkkkkk" of random length). After the install I end up with a corrupt disk (Grub Error 5 after reboot from LiveCD).
This is a very serious problem for me and I need help to solve it.
Another thing to know is that Mythbuntu comes bundled with the firmware on the LiveCD and that causes this behaivor by default. Ubuntu does not have the firmware loaded by default.
