Does anyone know where one might purchase a USB to ethernet adapter that actually works with linux? Preferably at a reasonably low cost.
So long as you use a recent Linux kernel (from, say, the past year), then I would be quite surprised if you could find any USB-ethernet adapter that does
not work with Linux.
But if you're looking for first-hand experience, then anything ASIX based has always worked, though the recent 2.7.37 kernels broke my own ASIX-based adapter.
For
cheap, there's always DX. I have purchased two
moschip MCS7830 adapters from DX. They work for me here, but they do need a fairly recent kernel on some USB ports (2.6.36 works, probably also 2.6.35).
Cheers
