The devices in embedded space accept kernel updates at various speeds. The raspberry pi is at 3.18, and the Intel Edison is bit lagging at 3.10. I thought it would probably be useful to the embedded community if I at least took a stab at back porting the hid gadgetfs function to 3.18 for use on the raspberry pi. Going farther back with more modules if there is interest. I searched through the kernel source and I think I've found the definitive list of gadget functions (grepping for DECLARE_USB_FUNCTION_INIT), and noted when they were introduced. 3.19 midi, hid 3.18 uvc, uac2, uac1 3.14 fs 3.13 mass_storage 3.11 subset, rndis, phonet, ncm, eem, ecm 3.10 serial, obex, acm I figured this list was probably the best place to ask if there were any caveats to taking usb/gadget/function/f_hid.c back one kernel rev.

Is there a better list to or talk/discuss backporting of usb gadget functions? -- 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
