    How to measure the current drawn by a USB device - revisited!

    I first asked this question in early 2010*, and I have only just found that there are now devices which will enable the simple measurement of the port voltage and the current drawn by any USB device!

    Here are just a couple, for interest (if any)...

    (Other fine USB Power Meters and sellers thereof are available...)

    * I can't reply to my original post since the thread is more than 100 days old!

    Ok my curiosity is peeked, why would you want to measure that. I am guessing that you think you might do that often as a 'bodge' (Aussie lingo I guess) was unaceptable.

    Just because you don't know where you are going doesn't mean any road will get you there.

    BATcher -
    Silicon Chip Magazine (Australia) published two kits which deal with USB ports. The one which would fit your need is a Voltage/Current/Power monitor Cat#KC-5516 in The JAYCAR Catalogue ( http://www.jaycar.com.au/catalogue ) on page 62. Although this is a kit, it is very simple to assemble. I have had this one for the past 3 years - works great!
