These cables are a crap shoot. I ordered one about 3 months, and was extremely pleased. It charged my phone as well as transferred data.

I just ordered four more to leave in various locations. The cable that I got looked completely different than the first cable that I received. The only reason that this concerned me was it shows that the seller either switched suppliers or multi-sources under the same part number. I plugged the cable into my phone. The charging light illuminates, but does not charge. I left my phone overnight and it died on the cable plugged into a laptop. I have since tried several other USB ports. None have changed the issue. Data is transferred to and from the phone.

I wound up cutting apart one of the cables. It looks like pin 4, the ID pin, is not tied to ground via a resistor or directly. I cannot find much on the subject, but my guess is that the EVO requires this pin tied to something to allow charging.

I was contacted by the seller, refunded, and told that the issue was resolved.
