IANAMOKC (I am not a master of kernel compiling), but I believe that
you also need one of the following modules: usb-ohci, usb-uhci or
ehci-hcd. You can find out which of the module you need, by writing
the following (as root)
lspci -vv | grep USB
Alternatively you can look at the specifications of the USB-port of
your computer (It will mention one of the words UHCI, OHCI or EHCI).
By the way, there has been several reports of people having problems
using pwc with OHCI ports. Search google for further information.

Good luck
