Why is my BB device manager is unable to mount the internal storage?

I have a new blackberry passport (2015) with software release 10.3.0.908,bb device manager is unable to mount the internal volume upon connecting the device with USB.but it was mounted the volume correctly couple of times but after that nothing.bb link & blend is installed with latest update & I am able to transfer files thorough blend.I want to mount the volume which I find easier to transfer the files.Please give me a solution.I am running windows 7 ultimate 64bit.

If you have the newest link, you should have the drivers. Open my computer and you should see the device memory as a drive. You can drag and drop from there.

Check : settings -> storage and access -> USB mass storage.

Thanks for answering.The problem is solved.It seems like avg antivirus was causing the problem.
