No voltage readings on USB pins 2 and 3

Post by Bokononisms »

Hello Everyone,

I am getting voltage readings from USB pin1, but not pins 2 and 3. Any advice?

P.S. Pictures were taken on a table, but the work didn't occur there!

I see several solder joints with little or no solder. The solder should wet the pin and the pad and form a cross section like the diagram below. Read through this guide for tips on fixing these solder joints:
