What are you guys using USB OTG for? As an offshoot of another thread, I thought I'd post some of my thoughts and ask for other ideas. So, post up! -------------------------- Edit: I thought I'd keep track of what we're using USB OTG for, so this could be a one-stop-shop for what works and what doesn't. Updated 08/10/12: Mass Storage: (ROOT ONLY) This post. The one you're reading. Further down. That's everything you need to attach a mass storage device to your tablet. Serial Communications: This post. Use your tablet to control devices using a serial cable and terminal emulation! Very handy for IT guys out there, or even a lot of gadget geeks. Keyboards/Mice: This post says that a Logitech K400 wireless keyboard/trackpad combo works nicely. A number of other wired keyboards and mice have been tested, too. Game controllers: This post says he uses it with an Xbox controller for games. Also, this post indicates that the PS3's Six-axis controllers work. Importing photos from a camera: This post proves that PTP picture mode works on cameras, and the N7 can import photos. Of course, mass storage mode on cameras works too! Camera controller: This post points out that you can use the DSLR Controller app to control your Canon camera via USB. Cool. Ethernet connectivity: This post has some details about using USB powered Ethernet network adapters to connect your OTG device to wired Ethernet. Handy when wifi isn't available, or for network troubleshooting. -------------------------- There is, of course, the obvious use. Storage. I've purchased this USB OTG cable. It was higher priced, but I liked the 90 degree bend could use Prime shipping. Along with that, I bought this 32gb HP USB drive which was dirt cheap and tiny. I've installed this kernel, which supports NTFS so that I don't have to re-encode my movies into smaller file sizes. You don't need this if you can stick to the FAT file system. Lastly, I installed Stickmount to mount and unmount the drives when they are plugged in. All of this works great. Stickmount is very nice for mounting and unmounting the drives, my 8gb test movie played easily, and I even tried plugging in my 500gb USB drive to see if the tablet would deliver enough power - it's perfect.
