ssh debian@beaglebone.local 

with password temppwd (you should change that)

sudo iwlist wlan0 scan | grep ESSID

sudo iwconfig

lsusb

My wifi and usb hub for the pocketbeagle kinda works now. Little mistake to fix with a bodge wire. @oshpark boards work fine :) I can scan wifi ssids but have trouble with setting up the connection.

Seems like there aren't any capacitors needed for the crystal, although it seems unusual coming from every other chip I've used that needed a crystal. I've added 10pF like in #(One More) Raspberry Pi Zero USB Hub but doubt they're necessary. 

Only one extra USB port has a plug, out of size restrictions etc. - a second one has the RTL8188 directly connected. Therefore only one LED is really necessary for the "connected" status. 

Added a PRTR5V0U2X as ESD protection for the "external" USB port.
