[LinuxBIOS] Enabling USB 2.0

Probably most boards enable USB. The irq_tables.c for each mainboard
has the IRQ map in it. I believe this file can be generated
automatically if you boot using the stock BIOS and run the generator
tool. I am working mostly on a system without a standard BIOS and am
coddling this file together manually. Either way, take a look at it to
get an idea of what it does. There have also been a fair number of
posts related to constructing this file, so search the archives too.
