Dear Experts, I resolved the issue, after some research. The transport_class_register() API is moved from PROBE method to INIT module as it is NOT per device registration, but, it is per driver registration. That is, for each driver, we need to register one time, but not for each device insertion. After moving the registration API call to INIT module, I am able to work with TWO devices simultaneously.
