Z10 no USB connection but charging from USB?

This is an interesting problem that I'm searching over the Internet from last few weeks. And finally posting here for a possible solution.

I can charge the Z10 from PC USB connection but no other USB connections like USB mass storage and connection to BB Link / Blend is not getting established.

Installed BB Link and Blend on my system and connected the Z10, but it says no device found. Even on Blackberry device manager (opened from taskbar notification area) doesn't show any device connection but at the same time it's charging from the USB port.

Few notes:
1. I can access my files using Wifi share.
2. OS version is 10.3
3. No SD Card is installed
4. I remeber on past, I accessed my Z10 internal storage without any drivers.
5. I can see a greyed out 'Removable disk' under My computer if I connect Z10 with USB mass storage / choose 'Access internal storage' from connection prompt.

Just in case, check Settings- Storage and Access- Access Using USB and make sure Charge only mode isn't switched on
