It says it's only been tested with CM10, but might also work with other ROMs. I finally got my Y cable, and I can confirm it works. [Using this cable from ebay, $6]

This means you can plug in your flash drive or hard drive and use it while on AC power!


Update: for 4.2.x check this dedicated thread over on rootzwiki: http://rootzwiki.com/topic/37755-tim...er-management/

Big thanks to XDA member t1mur and rootzwiki Timur for making the kernel!

This is awesome, just need to find a y-cable to try this out. Just hope its a stable kernel that doesn't cause any issues.

Hi Guys,

will this also work with a standard otg-cable and an usb-hub?

Cheers,

I don't think so for 2 reasons. Usually even powered usb hubs don't give out power through the input port [The source port of the hub]. And even if it did, it would be 500 mAh [the N7 charger is 2000 mAh], which [edit:] isn't enough enough to charge the N7 with the screen on. If the screen is off though, it will slowly charge it.

Also, apparently this is already implemented in Faux's beta kernel, you have to use echo to enable it [it's explained on the thread].

Awesome news, even though I just bought a regular OTG cable about a week ago for a $1.50 (still waiting for it to be delivered from China to the USA [NJ]). Since I just got a full-time job I'm going to sell my 8 GB and get one of the 32 GB versions when they become available so I won't have to worry about the extra cable

Can anybody confirm that it effectively works ?

Also, It would be good to to know:
- which Y-USB-OTG cable is used ?
- which power source, i.e. from a PC (500 mA) or a charger (2 A) ?
