Thanks for the reply. I am going to try a few different setttings (just the 3 I itemized above, until some one else here posts another option). Did you micro-USB Y cable for sale here in the states. I looked earlier today and only found that dual micro USB "Y" cable overseas on 'pimoroni' (https://shop.pimoroni.com/products/split-microb-usb-power-cable) site. Have you found it somewhere else? ------------------------------------------------------------------------ stereoptic's Profile: http://forums.slimdevices.com/member.php?userid=53162 View this thread: http://forums.slimdevices.com/showthread.php?t=103330 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
