[Nexus 7 (2013) Q&A] farfetch:
Hey guys, I got my Nexus 7 2013 some days ago; yesterday a bought an USB OTG adapter, but these devices that work on my Galaxy S4 doesn't work on my N7.

This is a list.

+USB 3.0 Pen Drive 8GB:

S4 (PA 3.99 rc2): OK

HTC ONE X (MIUI): OK

N7 (PA 3.99 rc2): OK

+Cyborg R.A.T. 7 (wired mouse):

S4: OK

HOX: OK

N7: OK

+Razer Onza (wired joypad)

S4: OK

HOX: NO (maybe depending by the MIUI interface, haven't game to try with)

N7: NO

+Logitech Anywhere MX (wireless mouse):

S4: OK

HOX: OK

N7: NO

+Trust wireless mouse:

N7: OK (I think i do not test it on other phones)

Now, this is my request:

Why a device that is recognised by my N7, and that works on my S4 with same ROM, should't work on my N7??

My priority is using that Logitech wireless mouse on N7.

These are the "dmesg|grep -i USB" outputs:

Looks like my N7 does not recognise my Logitech mouse as an input devices; also, in my S4 these is a USB2 folder, in N7 USB1. Does it mean something? Logitech mouse should be USB 1.1, and also my USB 3.0 Drive works, it shouldn't work on a USB1.1, am I wrong?

Thank for help
