Sounds really interesting!.. What about this project? http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2007/blh36_cdl28_dct23/blh36_cdl28_dct23/index.html Do you think it is something similar? If I understand well it is a software usb host implementation right? > You could take the same approach and try to apply it to the Ben > for the host side.

Could hardware people to help with the hardware side? I mean, for example, could we use UBB to plug some usb keyboard? useful to have the real hardware to try to develop the usb host software which will run in NN? No sure if I understand, but if the hardware part is something easy to get, at least for testing or starting point then more people could like the idea. At least it looks interesting for me, and I could start a 10 years software project to try that :) Saludos!, Rafa _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
