I have read the specification of OHCI USB only once.
I guess the OHCI specification for firewire and USB has no
concern, even if both basic concept to reduce driver developing
effort for each vender's products are the same.

You can obtain an OHCI chipset specification from

http://developer.intel.com/technology/1394/download/ohci_11.htm

Of cource I refered USB driver code before rewriting the firewire
driver. However, I believe it is difficult to merge USB and fiirewire
OHCI.
