I am using USB to communicate between two processors. Firstly it was working fine, but later during testing period it stopped working. The other Functionality of the controller seems to be fine. Is there any hardware checks to be done to ensure that the controller is fine.

Instrument your code so you can ​determine the nature of the failure, and if it is in a hard fault or error handler.
Use a bus analyzer if that will help pinpoint the nature of the issue. ​

Previously while USB was working , PA10 pin (OTG_FS_ID , but actually using as GPIO) was solder shorted to +15V supply. Will this cause any problem for USB function. After removing the short, the pin is working fine as GPIO but not working for USB Function.
