  Show int32/uint64 values in hex (without a leading 0x).

- *--verbose*

  Verbose output.

- *--help*

  Print out usage.

- *--version*

## RETURN VALUE

If both the property and device object exists the value of the property is printed on *stdout* and the program will exit with exit code 0. Otherwise the exit code will be non-zero.

## BUGS
