hi hippo,
thanks for the reply.
at first i tried with the 2.6.x kernel version which you can select ohci, sl11hs or isp116x. in that version, usb.c seemed to only include sl11hs stuff in the c source.
so i tried 2.6.15.4 next and when i select usb, it only has the isp116x option (ie. no options to select bluetooth support etc, which 2.6.x did have). this version of the usb.c had includes of sl11hs code and isp116x. as you mentioned, na_usb and na_usb_irq are both undefined. I was trying to figure out where to define those because even after replacing na_usb with the port and na_usb_irq with the IRQ, i still got a bunch of compile warnings and errors with the usb stuff.
any help to get the usb working would be greatly appreciated while i wait for the linux drivers book to arrive.
thanx!
