[Arm-netbook] irony: requirement for 100 A10 PCBs with GPIO-controlled power-up on USB 5V rail, or a Mini-PCIe socket

[luke.leighton]

hi folks,

part of the reason why things are very busy for me at the moment is
because i've started a new job, and - irony - they need a small
low-cost unit, qty 100, with 3G (HSDPA) and WIFI (802.11bgn).

but the requirements are *very* specific: the WIFI and 3G, which are
usually USB-powered, typically crash (for whatever reason) but they're
often 5V powered and you can't shut them down.

so what they need to be able to do is to flick a couple of GPIO pins
and power off - completely - the USB bus 5V rail.  or, if the unit has
a Mini PCIe slot for 3G, they need to be able to pull down the 3.3v
and 1.5v power, and back up again.

it's the basis of a reliable router box, basically.  oh - they also
need Ethernet.

so - irony, as the timescales are short, i'm looking at the hackberry,
and yes tom the cubieboard: i need to find absolutely anything where
the USB can be completely powered down, *without* power-cycling.

any help greatly appreciated.
