Dev?ce needed to be have USB, or you can also plug PS2 - USB converter for the job. I think some IRDA devices allows BIOS inputs and make them represent as USB mouse/keyboard device to BIOS. Those devices are not "?rda" compatible but uses IRDA for transmission. Also Wireless keybs & mouses are working. because those devices uses bios compatibility...
But if you have bluetooth devices, those devices could connected every other bluetooth device so they dropped BIOS input for that. You cannot use those devices on TV. You needed to load Buetooth drivers to TV first but I think they are not ported to linux 2.6.18 kernel.
I wish have samsung kernel object that compatible for 2.6.3x

So I don't think that we could support USB devices any soon.
