I have not found anything like data sheets or chip manuals for the various broadcom chips that make up the wrtsl54gs units I use. Are these available through any channel? Specifically, I'd be more than happy to work on the USB and ethernet PHY issues if I only had some information about the underlying chips to work with.
Alternatively... is there a low power < $100 unit with wifi, more than one ethernet, USB, and >=32M ram that uses well documented parts? (I'd switch to one of the x86 platforms and stop fighting all the hardware issues, but I need lower power.)
