I have a beaglebone black. the challenge I face is that I require multiple
powered USB devices to be connected to it while only using one power source
- the BBB 5V DC connector
1 - USB Camera - Logitech C920
1 - USB GPS Antenna
1 - USB WiFi Adaptor
1 - USB Bluetooth Adaptor
Clearly the onboard USB port cannot supply enough power using an unpowered
hub to bring these devices up.
How would I wire the external powered hub to the Beaglebone Black to
satisfy the single power source requirement?
1) Would I tie +/- to the same DC power source before the BB and somehow
adapt the USB cable for TX/RX only thus bypassing the board for the power
on the hub?
hub | ===tx/rx USB===|bbb 5v|======+/-
| +5V-------------------------------------| |
| gnd----------------------------------------|
2) Would I use the +/-5V expansion header and somehow adapt the USB cable
for TX/RX only? thus using the BB to supply power?
hub | ===tx/rx USB===BBBUSB
| +/-----------------------| bbb expansion header 5v |======+/-
I tried scenario 1 already and somehow destroyed my BB (won't boot, no LEDs
- looks like a brick), bit hesitant to try 2) as I don't want to brick
another.
I am not an electrical engineer.
Thanks-Wesley
