I can't find a pull request that would remove Stream.h , was it included previously ?

My assumption would be this removed it via classes that depend on Stream.h: https://github.com/ARMmbed/mbed-os/pull/12410 . It was a clean up of deprecated functionality.

I can see USB drivers are using Stream.h.

@kjbracey-arm @rajkan01 do you remember any detail about Stream class

Yes, previously Stream.h header included via drivers/Serial.h header file. As part of the cleanup, the deprecated class was removed and Serial.h the header in #12410.
I am not sure why that header file was not included directly in mbed.h header file instead

A missed bit. If the class is used (it is in USB drivers) so should be exposed, shouldn't be?

@rajkan01 worth fixing ? We can send a pull request

cc @adbridge if you got a chance to review this and fix?
