I'm using a powered USB hub, with USB-to-SDmicro adapters, to make copies (7 or 14 at a time) of Bible material in different Indian languages, for the Indian people of Mexico. The main problem that I'm having, is the poor quality of most adapters.

Does anyone have a source for really good USB/SDmicro adapters?

Sandisk seem to be well made and their price reflects that versus the cheap ones that are for sale at discount stores. I've never had one break yet but I only use it to transfer pictures and always treat it with "kid gloves"

I think I've sort of worked out which USB/SD adapters work best for me. They show no brand name, but are black plastic with a red top, and a short lam on them. Some of them work very well, for a long time and many uses. Others (that seem identical) fail after two or three uses. Thanks for trying guys. I'm still looking for a reliable source for the reliable ones, but I'm going to stop wasting time and money on it. I've got work to do. So, since I thi nk I'm as near a solution that I'll be able to get for now, I'm goin g to mark this solved.
