The commit which introduced TransducerSerialNumber (368c966) is missing two crucial implementation details. Firstly, the commit does not set the type/code/bit/max fields as expected later down the code which can cause the driver to crash when a tablet with this usage is connected. Secondly, the call to 'set_bit' causes MSC_PULSELED to be sent instead of the expected MSC_SERIAL. This commit addreses both issues.
