I'm trying to figure out which pin the VBUS on the USB connector should connect to on the AT91SAM7S.
Looking up the schematics of the various development boards hasn't helped.
The datasheet says this below, but not entirely sure what it means . . .
VBUS monitoring is required to detect host connection. VBUS monitoring is done using a standard
PIO with internal pullup disabled. When the host is switched off, it should be considered as
a disconnect, the pullup must be disabled in order to prevent powering the host through the pullup
When the host is disconnected and the transceiver is enabled, then DDP and DDM are floating.
This may lead to over consumption. A solution is to connect 330 KÎ© pulldowns on DP and DM.
These pulldowns do not alter DDP and DDM signal integrity.
