I’m looking at the schematics of the Seed and Pod, and am a bit confused about USB Host and OTG support. For OTG support there should be a switched Vbus line, while on the seed the Vbus is connected through a diode so can never supply voltage to the USB device.
On the Pod the Vbus is connected only to the protection circuit U7, so no power can be supplied there either.
Am I missing something, or is OTG support only meant for self powered devices or so? For bus powered devices even powered USB-hubs are not a solution as the STM32 usb host library apparently doesn’t support hubs.
