To allow a USB host device to detect a connected device and the supported USB Speed, a pullup is attached to either D+ or D-.
I dont find anything like this on the explorer board, so I assume there is an internal pullup on one of the data lines?

Hi,
The PHY has all the pull-ups built into it. The XUD library switches them on and off as required.
Cheers,
Henk
