Are you sure? I'm pretty sure I tested and found I could use a USB
mouse and keyboard at the login screen of my Nexus 7 (2012). You were
using a USB OTG[1] cable, right?

I had to open up my Nexus 10 to replace the battery. It's pretty fiddly.

Oh, wow. I'd not heard of that standard, nor that MMC could be
anything other than dog slow. Well, that does make sense though, and
sounds more likely to me now than a discrete drive in really cheap
tablets.

I'm guessing that the "charge/data link" switch just shorts the data
pins (D+ and D-) on the connector or something like that, but I
wouldn't trust it. Just use a regular USB cable and keep an eye on
your kernel output (`dmesg -w` before you plug it in) to see what it
manages to detect, if anything.
