Perhaps you have the older boards. google "Raspberry Pi Reboots on inserting a USB device" "by mahjongg ยป Mon Nov 19, 2012 12:09 am Don't hot plug USB devices directly into the PI, if you must hot plug plug into a hub instead! Its called "the rush in current problem", and it makes that the current PI itself is non "hot pluggable", note that the revision 1 PI was hot pluggable, as the two polyfuses prevented any rush in current because the fuses had a non zero resistance. But in the current board there is literally zero resistance between the PI's 5V supply, and any USB device you plug in, that means that if you plug in any USB device with empty power decouplers, (which act as a complete short for a very small time) then you are actually simply shorting the 5V when you plug de USB device in. The polyfuses in the revision 1 board however caused much greater problems than this problem, and for that reason have been removed." _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
