I've managed to configure and install my stuff into a raspberry pi and everything works fine while connected to a power supply, however in a USB battery pack the situation is different.
I've the following:
- 1x Raspberry pi (b)
1x Anker Astro III 10000mAh External Battery (http://ianker.com/Anker-Astro-10000mAh-External-battery-External%20Baterry/goods-43.html?&cat_id=17&line_id=114)
1x USB Hub with power port (http://www.ebay.com/itm/140773628651?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649)
1x Alfa AWUS036H
As you can see on the link the Anker Astro have 2 USB ports, I'm connecting the Raspberry Pi on the first one and the USB Hub power cable on the second one.
If I start the device with the USB Hub connected it won't boot, the LEDs are all turned ON but nothing happens at all.
If remove everything and just leave the Raspberry Pi connected to the battery pack it boots up fine.
Any tips? Thank you.
