SmoothStepper USB / Re: SS MPG output current?

Hi Brett and Greg,
Thanks for that info. I guess that a sourcing pin would not typically use to much current, but if you had three pins using 30ma each, then you would be pretty close to the 100ma standard USB limit. I did get an error message from windows stating excess USB current with a Galil controller I was playing with about a year ago, so I guess there is some level of protection built in to the computer. I will give the MPG a try and let you guys know what I see. Thanks again,
Jim C.
