Can you make OTG work with something like this? Or is the cable an absolute necessity?

Usually, only cheap cameras have built-in flash. Either way, accessing the built-in memory or the removable flash card on a camera should both be simple if the camera supports OTG. Most if not all non-dSLR's don't, and even lots of dSLR's don't.

My Nikon D80 does though, and I'm waiting to get to Radio Shack for an adapter to convert the non-N810 side of Nokia's cable from USB A to mini (what the camera takes).

I don't know if an adapter can in some way make a USB OTG cable non-OTG-compatible. I'm a tad confused about that, since all of my OTG devices (my Nikon D80 camera, my iRiver X5 MP3 player, and now the Nokia N810) came with cables, ostensibly because they're OTG-capable.

Actually, my MP3 player that does USB OTG has a proprietary connected--looks like a mini USB jack but with a different shaped metal housing. So, that's also a hint that these cables are usually included because they're required to use OTG with the device.

Anyway, I initially replied just to say that the N810 comes with a USB cable that (needless to say) fits into the micro USB jack on one end and has a regular, male USB A plug on the other. Getting a female-to-female plug for regular USB A would let you then use any USB A-to-whatever cable instead of finding an adapter for everything.

Or, find an adapter for what you need. It depends on what cables you've got lying around and what you'll be using this for.

You just have to connect id and ground at the host (OTG A) side:

some users have reported that they don't have to switch on the n800 to host mode manually when they connect pin 4(id) and 5(ground)

Anyone experiment with usb mice or keyboards?

USB keyboard should be a breeze. I have even connected a wireless USB mouse to my N800 via a normal cable (using the `echo host > ...` command) and got some garbage output into /dev/input/mouse0 whenever I moved the mouse. I also got the cursor displayed. The key problem is that I dunno how to connect the two
Everything should be identical on the N810.

It should be the same as on the n800 with os 2008:

(from post #36 on should be intresting for you)

I bought this for my n800 http://www.twstore.com/gcusbafxm.html and decided to upgrade to the n810, will that adapter work with the n810?

The pictured item will not connect directly to the N810.

N800 = Mini receptacle
N810 = Micro receptacle

well that sucks.
