Realtek USB 2.0 Card Reader?

Hi,

I have Fedora 17 installed on my Toshiba C855-S5308 laptop, and I have almost everything working, except for the card reader.

In Windows, it says it's "Realtek USB 2.0 Card Reader".

In Fedora, if I run lsusb, I get "Bus 001 Device 003: ID 0bda:0129 Realtek Semiconductor Corp", which I think is the reader.

From googling, I believe that the chip is an "RTS5158", but I can't find a driver for it.

Does anyone know if there's a way to get the reader working on my laptop?

Thanks,
Jim
