Thought I would give one last update. My Joye 510 pass through is no more. I am using the parts to make mods. When I took the battery box apart I found the circuit board that is probably to blame. It has Pillbox 38 screened on it so I assume that was the producer.
If you are having poor performance with your pass through, of the same type, you might consider this fix. It is possible to bypass the circuit board and remove the battery. If you are comfortable tinkering with electronic equipment that is. You should visit the modders forum and look at the things they have there any go through the tutorials.
A better idea is to look at the pass through here
USB Passthrough - . I don't want to suggest that you need to modify your equipment if there is another option. If your pass through is still in warranty you should contact the vendor you purchased it from and get an exchange or refund.
I have created my own pass through and it works like the one I bought should have. I believe that the problems I and others have experienced are a quality control problem because there are some users who have bought perfectly good models just like mine.
