libertas

The libertas driver made it's debut in the OLPC laptop, where drives an Marvell 88W83886 USB device. Later driver front ends for similar chips which use compact flash or SDIO have been written.

device firmware

All devices need firmware. For the USB firmware, go to Marvell's driver download page and search for OLPC.

For CF/SDIO, get the firmware extractor utility via

  • git clone git://git.infradead.org/users/schurig/libertas-tools.git tools

There's a makefile in there that will do the job. Then you will have two files libertas_helper.fw and libertas.fw in the fwcutter/ directory. Copy both files into /lib/firmware/ and the driver should be able to load it automatically when you insert the card / powerup the device.
