The documentation states that the lower usb port is "USB-C 2.0 + Power Delivery (device mode by default & power input)". Is there a way to put it in host mode and use it as a regular usb port ?
Does it needs a change on the hardware side, the kernel driver (.dts file), a setting file, some command ... ?
The upper usb port is usb3, host mode only. But not all usb3 devices are recognized. Is this the same problem as with the Quartz64 board: "USB 3.0 (applies to Model A only) — only works with very short cables and depends on the device."
Example of device not recognized (hub has usb2, usb3 and ethernet):

Connecting the usb drive directly to the usb port (without the hub) works as intended:
Same questions as with the lower usb port: is this behavior hardware related, driver related, dependent of a setting, ... ? Are there usb3 hubs with a RJ45 port which are correctly recognized as usb3 ? Since (for the moment) we need the usb port to provide a network connection, it would be nice if usb3 is also available using a hub so we can enjoy better speed (x10) for networking and other connected devices as usb disks.
