I just picked up both a USB OTG hub and the NP controller. I want to do some gaming and emulation on the NP.

I know marshmallow has been kind enough to allow us to format USB sticks as internal storage and I want to move some bigger apps over and whatnot.

I got this OTG hub and am running power to the dongle. http://www.amazon.com/Hittime-Adapter-Extension-Smartphone-Tablet/dp/B00FGKXY9S

I'm using stock unrooted 6.0 marshmallow.

So here's a couple problems I'm having:

I have a 32GB Sandisk Cruzer Glide that I want to use for this. The drive is constantly being "disconnected" and the formatting seems to fail.

To figure out if I have a bad stick (i'm fairly certain its not as it works great on PC) I use a cheap 2GB drive I picked up as swag from a trade show. This seems stable and does not disconnect. The problem with this is, I moved a large app (1.3ish GB) over to the USB. In the storage menu, I see the 1.3ish GB used in the apps category but I also see 1.7GB in the available category. The NP STILL shows as only having 458ish MB free despite just moving 1.7GB off of the device. The app also shows that it is installed to the USB.

Is there something I'm not understanding about how this is supposed to work? Is there some drive compatibility issues that are common?

Update:

A smaller 8GB Sandisk is showing the same issues. Keeps disconnecting and I get: "unfortunately, settings has stopped"

I tried a factory reset and have the same problem. I'm going to try and flash the factory image to see if that helps. The current install was an OTA from Lollipop.

I'm also having issues with fastboot and adb connecting from ubuntu. I guess the copy in the repos is out of date and I need to grab the SDK in order to get the latest fastboot. I'm going to try the Nexus Root Toolkit from a windows machine instead.
