ok - so this goes to him too :-)
Pete, i don't know if you have seen my previous posts... I did now have a look at the comments in ub.c Looks like the driver is very new and a lot has yet to be done. I cannot really tell what of the points on the todo list may be related to my problem. I miss information and "ub" isn't really a good keyword to google for either.
What is the difference to the usb-storage driver? What is the state, what are the plans?
