Hi,
there is a discrepance between
TPS65950 Schematic Checklist (Rev. B) (swca073b.pdf)
http://focus.ti.com/lit/an/swca073b/swca073b.pdf
and
TPS65950 Data Manual (Rev. E) (swcs032e.pdf)
http://focus.ti.com/lit/ds/swcs032e/swcs032e.pdf
about the USB ID configuration, when this function is not used.
According to the schematic checklist, it has to be left floating. In table 2-2 of the data manual, we recommend to connect it to VRUSB3V1.
What is the correct configuration? On the beagle board it's left floating.
Best regards
Massimo
