STLink discovery board not be able to communicate with laptop without USB Mass storage enable which is against our corporate policy. Pease help to get the solution to debug the target with STlink without enabling USB

If I understand correctly the problem is the normal STLink has a bit aof FLASH space that gets mounted over USB as a FLASH Drive.

Possibly these would work for you (test to verify if suitable):

Test these on an unrestricted PC (home PC?) before using the devices on Protected PC.

1) Update the firmware on the STLink, and when option is offered disable the FlashDrive option.

(I believe I saw this option recently after updating my IDE)

2) Use Seggar JLINK, which I believe doesn't have Flashdrive.

You can also update firmware on JLINK to make it behave like STLINK above.
