Is there anyone who claims ownership of the kernel hc_simple code that
the isp116x driver uses?

Not that I've noticed.



I'm thinking its about time to clean up the isp116x driver and submit it
to usb-devel/lkml. But that does require resolving some merge issues
with the hc_sl1811 driver thats already there that also uses hc_simple.

It'd be a lot better to do this in the context of the 2.6 version of the "hcd" framework. (Then backport to the 2.4 version if needed.) That framework is more capable, and is also used by the "mainstream" ehci/ohci/uhci code ... so most of its bugs have already been shaken out, at least on 2.6 kernels.

Using it for the isp116x may shake out a few pci or dma issues, but
the resulting driver would of necessity behave a LOT more like the
other HCDs do.  (Assuming you use the "usbtest" framework to put
that isp116x hcd through its paces!)
