Smartphone SD card reader?

[jerkbait]

To all you super smart ones out there. Is there an SD card reader that I can plug into the micro USB slot on my Droid and read my SD cards from my trailcams right out in the field?

Thanks,

Chris

I was just looking for something like this the other day.

I found a bunch of stuff that seems like it will work, but nothing with a well known company's name stamped on it. Mostly stuff on that online auction site that ships out of hong kong.

seems like it's phone specific too, your phone must have USB OTG (On-The-Go) capabilities to act as a host for plugged in USB devices.

I was just looking at one on new egg and was wonderi ng what OTG was. Would be pretty cool. How do I know if my phone has OTG? My first smartphone, so I am still being outsmarted.

not sure how to tell other than taking your phone manufacturer/model and googling it. Post the info here and maybe somebody can help.

Sounds like it's a combo of android version, android version specifically adapted to your phone, and your phone's hardware.

as best as I could tell, my phone's (HTC Sensation 4g) hardware prevents it from supplying power, even if the operating system has no problem with serving as a host for USB devices. So I would need a USB OTG cable that has an AC adapter to supply the power to the USB device.... I know that makes a difference for something like an external hard drive that needs some juice to power up, not sure about a simple memory card reader.

It is a Motorola Droid razr m. I think it may have OTG.
