This is why I love the N900, why I clicked "Thanks!", and why I just donated.

I built a USB powered Super Nintendo controller using a Teensy 2.0 microcontroller to act as a HID keyboard, connected via a non-powered hub, and also running a 4Gb flash drive with all 763 SNES games released loaded on it. This morning, I connected it to my N900 and managed to mount both (literally by pushing "Mount" twice on Full Speed Mode) the flash drive and the HID keyboard without an externally powered hub.

I was playing SNES via DrNokSnes with the proper controller with access to ever single game, basically. I didn't catch the kernel log, but it was exactly what you would expect for two perfects mounts.





Now all I need is to be able to charge at the same time while using H-E-N and I'll be set!
