Hook up

USB_DM to Data-
USB_DP to Data+
+5.0V to Power
GND to Ground

USB want a balanced line for the data, I have never gotten it to work with jumper wires. I soldered a piece of pin headers to a socket so my data connection is < 25mm total. The power can be wire up with jumpers.

Another question, please.
Is this USB connection able to act as a "host" USB. Or is it just acting as a slave. It appears to be able to act as a host since you can just connect a USB camera (slave) to it. But no-one really comes out an says it can act as a host.
Thank you

VoCore2 can not be USB slave, but VoCore USB can be.
All of them can be USB host, connect to camera or usb disk.
