This may be way off topic, but the inrush current problem is probably with devices not meeting the USB specification. As it turns out, a lot of low end devices do not meet this spec. I spent some time redesigning the power supply system of one such device I was using. This time was covered by

What do you need to know? Most of the details will depend on what software you are running on it. Which operating system. After it boots up you can look in one of the log files. But details vary with the OS. On Wed, May 22, 2013 at 6:31 PM, Jim Sanford wb4...@wb4gcs.org wrote: Do you have

Newegg has a refurb'd netbook for $40 right now and new ones for $100. These are complete systems with LCD display, case and battery power with AC adaptor and still cheaper than a Pi or a Soekris. The reason to buy the pi, Ardurino, Launchpad or whatever is if you intend to hack the hardware.

$20 each is a fair price. I bet if someone here were to buy a lot of five (for less than $80) they could unload 3 or 4 of them here for $20 each shipped. I'd take one (at least) but have no use for five of them. The only good time-nut use of these is that some one has already figured out and
