Hi,

I currently rewrite the dma stuff and pci initialization of the 
pci-bus-driver. As you can see in the README, the adapting of the existing 
usb driver is the step afterwards.

I want to stick to this order, because there will some changes in the 
flexcop-part, that will require changes in the usb-part as well.

Maybe this weekend I'll find the time to create a first working usb 
driver.

dvb-kernel/b2c2 is compatible with dvb-kernel/build-2.6

ie. make in build-2.6, make in b2c2, run ./in.sh in b2c2 is the way to go.

Unfortunately your patch is non-unified, so hard to read for me. Can you 
send me a 'cvs diff -u' privately. I then have a look, what I can use 
from.

Thanks so far.

They are not public, sorry.

best regards,
Patrick.
