Nope! You cannot attach a USB Drive the Nexus 7
Jun 29, 2012 3:13 PM –
Sorry friends who asked me, “can you attach a USB drive to the Nexus 7“, you cannot. The reason it was asked so much is because it comes in 8GB and 16GB flavors with no SD Card slot for additional storage other than the cloud… and I’m sure this is what Google intends you to do with the device. Fingers crossed some hacker will break this rule! If it happens, you’ll be forced to attach a USB adapter but it will give you the benefit of a ton of additional storage!
