Any troubleshooting appreciated on SF's Pro Micro

sorry for lagging reply. I am still at work and only sneak out to test my board. But I do appreciate your suggestions. i will be heading out soon though.

mark2833, I understand your point. However, I do not even have the notification of USB not being recognized.

in0, I will find some more cables. Tried almost a dozen already including 3 samsung micro usb. But I like your info that power connection is established yet data is not. so will look for cables.
