I would imagine someone has an HID peripheral Ken> implementation started. I did a quick little proof of concept hid keyboard emulation using gadgetfs a few days ago. It's very raw, but enough to show me that it is feasible. For development, I would very much recommend you to use gadgetfs and dummy_hcd, that way you can do most of the development without hardware. I will probably move the final implementation to kernel space so I can use the composite stuff to run g_serial at the same time, but for now gadgetfs is fine. For details, look at the HID class specification on usb.org. It's quite simple (from the device side atleast). Anyway, you can get my hacked up code (based on the gadgetfs example from http://www.linux-usb.org/gadget/) at: http://git.korsgaard.com/cgi-bin/gitweb.cgi?p=hid-gadget (gitweb) or git clone http://git.korsgaard.com/git/hid-gadget/ -- Bye, Peter Korsgaard -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
