Im so frustrated right now. Built up a nice head of steam while setting up Ubuntu and fleshing out the Wiki.. Only to be stumped with an issue with the Silabs cp201x driver crashing!!! I'd been daudalling along nicely until this BHAH!
Anyway, it looks like the Silabs linux driver source requires parts of the kernel source to build the driver module :S
Took a while to chase down the right packages, but have the kernel building now, and the Wiki is up to date with progress.
