Hello, I have these patches from last October when we've looked at what causes problems with mac99 and USB. We've found the main problem is likely not allowing pending packets per endpoint which we did not fix but these patches came out of debugging that and trying to improve the device model so eventually the real problem could be fixed more easily. So these are just clean ups and fixing one potential issue with isochronous transfers breaking pending async packet but it does not solve all problems OHCI currently has. I'm sending it anyway as I don't plan to work further on this so this series could be taken as is for now.
