Use the setup failing with
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Generic Connectivity Using ODBC][H006] The init parameter
<HS_FDS_CONNECT_INFO> is not set. Please set it in init<orasid>.ora file.

There is a typo in the name of you gateway init file. You posted the content of inithMYSQL.ora but the naming is init<SID>.ora which is in your case initMYSQL.ora.
In addition please keep in mind HSODBC has been desupported since 2008 and when starting a new configuration you should use the follow up product dg4odbc (Database Gateway for ODBC) V11.
