Maginon SZ 24 camera and I would seem to have lost or mislaid the USB charger lead. The same socket serves for an A/V connection and that I have. It is like an horizontally flattened D and probably 4x pins, but difficult to see for sure. Length is height of D, width is the width of the D. Length is smaller than a mini-USB. It has two square corners and two tightly rounded ones.
I have several USB adaptors, but none match. I have also tried to find a match online, but failed - has anyone any ideas please?
