[Shop-talk] usb outlets

Don't have any experience with the outlets, but would like to warn 
against using your PC or tablet as a charger, as some one mentioned. 
Most current phones and other devices have a standard micro-usb jack for 
charging, but are "dumb" and do not communicate over it, and may exceed 
the allowable current draw. And thus can fry a host USB port. Had to 
replace a mobo' in my aunt's PC last month for it.

Per the USB spec that you can find on Wikipedia, a device is "allowed" 
to draw <= 100mA initially, and can then communicate with the host 
controller and "request" to draw more current in 100mA increments, up to 
500mA. If the device can communicate via USB, then it should follow the 
standards; if it's charge-only, beware.
