Anyone know how much current you can safely pull of the USB 5 volts? I would like to use that to run my SSR relays and remove a 5 volt power supply that I am now using. Thanks Carl

I think any USB host needs to supply the minimum (100 mA) and most
(except perhaps hubs) should supply the maximum (450 mA) OK
