I'm trying to get the g_hid module working with the Intel Edison.
I tried just compiling intel's patch(1) to 3.10.17 with
CONFIG_USB_GADGETFS=m CONFIG_USB_G_HID=m but I get an error trying to
load the module:
modprobe: ERROR: could not insert 'g_hid': No such device
According to https://www.kernel.org/doc/Documentation/usb/gadget_hid.txt:
In the very same file there is an example platform driver; well, at least
the most important hid-specific parts of it. You must add the usual
module boilerplate code and in module's init do platform_device_register(),
while in module's exit do platform_device_unregister().
You might also want to have a look at a configfs-composed gadget,
where the hid function does not require creating nor registering any
platform devices; the report descriptors are passed through
a configfs attribute (file). For more information you can have
a look here:
