The code from the remote and the defines in input.h aren't in any way directly
related. If the button that generates code 28 is rewind, map it to KEY_REWIND.

However... I just realized that I missed a conversion step. 30 is base 10, the
values in the config are hex. 30 -> 0x1e. Same decimal to hex conversion needs
to be done for the code values as well.

'dev=30 code=28' in dmesg for the button labeled rewind -> '0x1e1c KEY_REWIND'
in the haupp file.

No direct correlation. Look at the existing mappings, they have 'dev=30 code=10'
-> 0x1e0a KEY_KPASTERISK. KEY_9 is 0x1e09 -> dev=30 code=09.
