I tried, Stickmount tries. You can tell its trying to work something out. So more tests with a cut up usb cable on the OTG cable does in fact show there is a voltage issue. My Galaxy puts out perfect 5v. The Kindle puts out around 2.5v. I tried making another OTG cable but failed. I guess its just not getting connection to the extra pin. So I have a USB Extension I'm gonna split open and power it. So I don't have to hack up my only working OTG.
The main issue I'm having with this is, my current power unit is a measly 0.75a. And It charges the device. So I figure there will still be a voltage issue due to the device charging. So I could cut the red wire going to the device for now. But not sure if the device will realize this somehow and just not work. Thoughts? I've seen this done before when someone made themselves a powered OTG Hub system out of a couple USB Cables.
I'll continue till I'm too tired to think hehe.
Ok couple hours later.... lol I had a USB Extension, I cleanly just slit it down the m iddle and soldered in the two power wires from a samsung micro usb charger. The Power is 5v at 0.75a. So its not much. I know it wouldn't charge my nexus nor Galaxy Tab, but it charges the Kindle, or at least the kindle says it is. I doubt it really is. Anyway I soldered it in, cleaned up the surgery started some testing on my phone first. I connected a Micro USB cable to one end and then the other to my phone, and then the Kindle. It charges, or again says it is (*kindle might require more amperage). So Next I connect the OTG Cable to the other end and connect it to my phone, It charges through the OTG Cable. Next the Kindle, it does not charge the kindle. Possible amperage requirements, I don't know yet.
So onto the test without StickMount, Failure. It acts the same.
Test with StickMount, Well I'll let this screen shot explain most of it:
It worked! StickMount notification pops up and I found the flash drive in the current location. Inside the SD Card under a folder called /usbstorage/sda1/. Not exactly my first choice, not sure if this can be changed to go into mnt or somewhere else. The Device itself doesn't notice the flash drive. So if you go into System/Storage, it does not show the flash drive. But it is fully functional. I accessed some files without any issues.
So my final consensus: The Kindle Fire 2 currently has OTG/USB Host Capabilities. From the USB Host Diagnostics I ran, its fully functional. However the main issue is Power. The second issue is the device on the most current (1/20/2013 CM10.1 Nightly) rom doesn't have the proper... I don't know the right wording for it, but lets say drivers since I'm a pc guy. I'm sure with more development, it can control any device with the only issue being power related. This takes away from the meaning of "On The Go". Having some sort of 5v power source connected to your device while your trying to use a hard drive or something else is going to be a pain in the ass for most people. For me it really does not matter since the device is going to be setup in my car for media sourcing as well as game play. So a 32gb flash drive and a Xbox 360 controller is all I will be using.
I will be doing more testing with multiple devices but it is 4am right now. One more thing, Bluetooth abilities are possible with a cheap dongle. However for some reason the Kindle recognizes it as a physical keyboard. I have tested this on other devices in the past so I believe it is possible with some more development. But that's far in the future and still of course require additional power.
