Macbook Pro goes off whenever I connect MP Ultra

Hey,
I recently purchased a new macbook pro with touch bar.
For the past few days My Passport Ultra worked fine but starting yesterday whenever I connect my Passport cursor doesn’t move and after a few seconds my computer shuts off. Is there any way that i can solve this problem?

Hello,

I haven’t this issue before. Is this happening with a different Mac?

Have you tried changing the USB cable?
