VBSCRIPT execution gives the error [MySQL][ODBC 3.51 Driver]Access denied for user '[username]'@'%' to database 'databasename'

[pavan tasgfr]

I Have a VB script which will download the data from MYSQL server with version 5.6.
Previosuly it used work properly but when we upgraded from 5.5 to 5.6 it is giving the error.

When I am executing the vbscript it is giving the following error:

[MySQL][ODBC 3.51 Driver]Access denied for user '[username]'@'%' to database '[databasename]'.

The connection string i am using is as follows:

Conn.Open "DRIVER={MySQL ODBC 3.51 Driver}; SERVER=***.***.**.***;DATABASE=[databasename]; UID=[username];PASSWORD=[password]; OPTION=3"

I also used the drivers {MySQL ODBC 5.1 Driver} and {MySQL ODBC 5.2a Driver} instead of 3.51 but still it gives the error.
is there any connection string or driver issue.
