Calciphylaxis. Calciphylaxis is a condition characterised by necrosis (cellular death) of the skin and fatty tissue. It is seen mainly in patients with end stage kidney disease. It is also sometimes called calcific uraemic arteriolopathy.
Besides a data link, USB provides 5 +/- 0.25 volts to power an otherwise unpowered device or charge a battery in a self powered device. A USB controller or hub is required to power one unit load (100 mA, a low power load). It can optionally power up to 5 unit loads (500 mA, a high power load).
Anyway it's good to know that even if the usb wall power supply provides more power that the dss2 needs it will only take as much as it needs so all I really need is a usb power supply that provides 500ma @ 5v or 380ma @ 5v (380ma @ 5v) is all the dss2 pulls I think thats what the max means.. Yup, you are correct.
