This driver is a basic keypress input driver for the Keyspan Digital
Remote with part number UIA-11.  Currently there is an older remote with
part number UIA-10 which isn't supported by this driver.  Support for
the older UIA-10 could be added but a binary file is required to be
download to the device, and I don't have that file.  I also don't have a
UIA-10 device so I wouldn't be able to test any of the changes.
