I am using a RPI3 and have a GPS USB module and 3g USB dongle connected to the USB ports of the pi. I am using a 5 volts, 2.4 amps power supply. I was wondering if the RPI3 USB ports provide 1.2 Amps by default or only 600mA per port ? Because sometimes when initially powering up the system, wvdial fails (ppp dies, exit code:10), and then I reboot and it works. This keeps happening randomly.
If the rpi3 USB port provides only 600mA by default, is there a way to increase it to 1.2 amps in the software ?
Or do I have to just use a USB powered hub or just connect a y cable to 2 ports of the Pi and the 3g dongle ?
