So it seems you are using PHY inside TPS659x but external Vbus for which I think you need to,

1. Explicitly set "OTG_CTRL.D5 = 0" so that PHY doesn't drive 5V.
2. Do not set musb_cfg.extvbus

Great, thanks for clarifying (and agreed on all points).

It seems the best I can do is turn off DRVVBUS as soon as the chip has entered host mode (and turned thus it on).

Thanks, Orjan
