This driver will work with the PEGA-KB11 keyboard for the PEG-SJ20 and PEG-SJ30 Sony Clie PDA's - maybe others as well. For some reason, Sony does not provide this driver on their website, and no one at Sony seems to know anything about it. Even the parts department didn't have a listing. It seems to have fllen into a blackhole somewhere. Good luck!
