i have a power usb problem:
my configuration: raspberry, power supply AC 1A, hd 2,5" external usb self-powered, wi-pi wireless adapter.
i can connect both usb device and start raspberry as usually. but after a couple of hours raspberry became unreachable in ssh and if i power on the monitor it show a black screen. i think it's a power supply problem (wi-pi + usb hd). i read in this forum that can be some solution by means of some mods on cmdline.txt
can you tell me more so i can solve this problem and use both wi-pi and usb hd?
thanks so much in advance.
