I need to use the pwc (Philips webcam) module.
I see it enabled as "M" (build as module) in both make menuconfig and make config in the stock svn-trunk download. But it doesn't build.
I'm building for the brcm47xx-2.6 target, and in the config file there, the PWC option CONFIG_USB_PWC=m isn't in there; in fact none of the USB options for CONFIG_USB_HID are there.
So my question is: is there a problem that this package is enabled but doesn't build?
How can I regenerate the config file for a given target architecture?
I've read and read, but can't quite get my head around how this ought to work.
