Photon supports like plugging USB keyboard in right??

Depending on your kernel, which is very heavily dependent on the ROM you are using, yes.

However, you will need a few things:

• Research before you start.
  
  
  
• A USB Host Cable: This grounds the 5th pin (the "Host ID" pin) so that your Photon hardware knows to take over devices connected to it:

  USB Host Cable: Example: Amazon

  
  
• A USB Y Cable: Your Photon supplies a miniscule amount of power (about 100mA) so you will need to make or purchase a USB Y Cable. This will allow your USB devices to be powered from a charger while connecting to your Photon as host:

  USB Y Cable: Read about it here.

  
  
• A charger with at least 1A+ (1000mA+) of power. You will want to keep the phone charged while powering accessories.

  A Note of Caution: You can find this in many places. Remember that the power rating is very important but be aware that a cheap charger may overvolt under certain load conditions and damage components. This isn't incredibly common, but it can happen. Just be mindful. I use an iEssentials 2.1A charger that I found for a reasonable price.

  
  
• A handy app called:

  USB Host Diagnostics by Chainfire:Find it here.

Remember that support for USB Host Mode must be built/baked into the kernel for OTG to work.
I use:

Cybik's CM7 Nightlies
Oleg Fusion 1.3 CM7 Kernel


A few things I forgot:

If you can only find a USB Y Cable with three male connectors, you will need a USB Female to Female adapter (AKA Gender Changer) to connect a male end of the USB Y Cable to a USB Hub or Accessory.

USB Gender Changer: F/F:Example: Amazon

The connections should look like this:

• USB Host Cable to Phone
• USB Y Cable: Male to USB Host Cable: Female
• USB Y Cable: Male to USB Charger: Female
  
  
  with gender changer:
• USB Y Cable: Male to Female/Female adapter to USB Hub or Accessory: Male
  
  
  without gender changer:
• USB Y Cable: Female to USB Hub or Accessory: Male

YMMV. Good luck!
