Short comment - An example kernel configuration would be nice in a readme

Hi,

There is some work left to do there. 

Any help going through the USB library would be appreciated.

Not at the moment, but I could possibly extend "usbconfig" to list available

quirks. I've made a note for this.

No. You will have to inspect the module "DATA_SET()" information in the kld.

They exist to make loading USB drivers easier. It is simpler to 
load "usb2_serial" than to emperically search for a specific serial port 
driver. In the future the "usb2_serial" module will load the correct driver 
for you.

Yes, of course you can still ungroup the driver modules into smaller parts, 
simply by moving the source files to another module, or removing the source 
files for the drivers you don't want. But there are no kernel options that 
will do that currently. You have to do it by hand until further.

I have made a note for this.

It is BSD licensed like the rest of the code.

BTW: I will travel to EuroBSDcon2008 tomorrow and will probably not have 
access to e-mail all the time.
