Added the ability to query the
Manufactur, product name and serial number strings from a device.
WIP - Eats up lots of memory, next up experiment move from Device_t object to maybe top level objects. Probably fewer than them as each hub allocates something like 7 Device objects
I updated the keyboard extras to detect if the report ID is 0xff00 and if so ignore it in the Mouse extras process code. This helped not handling a lot of extra messages generated by MS keyboard.
Also updated Test app to show names of some of these special keys.
This delta, adds an extra keyboard object to handle those keys that are not part of the main keyboard class. In particular there are separate HID reports for some of the keys, such as Power keys, and multimedia keys.
These reports might be on separate Interface or in cases where the mouse and keyboard are on the same device, the extra reports may be on the Mouse Interface.
So far I have not tried to combine with Keyboard object as might require multiple inheritance which I would like to avoid.
Also I extended the special key mapping table to map several other keys like F1-12, Arrow, Home/end... To special values where the 0x80 bit is set. I used the same values as used for the Arduino Keyboard library. I did not use their defines as they used defines like KEY_F1, which already exists in core, but in core it is the scan code from the keyboard and not the end user value.
There is an issue with the extra items added to the report after the main known items.
Problem was HID report descriptor does something like:
Usage Page; Desktop (01)
Usage: 01 (Pointer)
Count xxx
Problem is the Usage values below 0x20 appear to have some other standard meaning. Which you can see in
http://www.usb.org/developers/hidpage/Hut1_12v2.pdf
So current fix is to ignore Usage values passed in < 0x20...
Appears to fix PS3 Right joystick
