Since 2.6.27 or so, the gadget stack has supported composite drivers. So for example you can have a gadget supporting both CDC Ethernet and CDC ACM at the same time. (Not too much more than that on a DaVinci though, because of hardware limitations.) > From memory, I never got the 'gadget' mode stuff to work on the DM6446 > EVM as I seem to remember some 'rewiring' was required and we were not > prepared to modify the hardware. No rewiring; just take the jumper out. But you'd need to use some kind of gender bending cable to connect to the host. > It does work on the DM355 EVM but it is > not OTG, that is the USB driver has to be built either as a host or a > gadget stack.

In any case, given the patches I posted this morning (updates of stuff I posted a couple weeks ago), DM355 EVM supports that role switching. - Dave _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
