With the release v0.4.0 the USB host is not working in the Lichee RV Dock. I downgraded to v0.3.3, and USB devices are working there.

U-Boot is detecting USB devices with both versions (in this case a USB Mass Storage device):

starting USB...
Bus usb@4101000: USB EHCI 1.00
Bus usb@4101400: USB OHCI 1.0
Bus usb@4200000: USB EHCI 1.00
Bus usb@4200400: USB OHCI 1.0
scanning bus usb@4101000 for devices... 1 USB Device(s) found
scanning bus usb@4101400 for devices... 1 USB Device(s) found
scanning bus usb@4200000 for devices... 2 USB Device(s) found
scanning bus usb@4200400 for devices... 1 USB Device(s) found
       scanning usb for storage devices... 1 Storage Device(s) found

With v0.4.0 I see in the Kernel log that the probe of the USB hardware is deferred:

[   31.186292] platform 4101000.usb: deferred probe pending
[   31.191702] platform 4101400.usb: deferred probe pending
[   31.197098] platform 4200400.usb: deferred probe pending
[   31.202494] platform 4200000.usb: deferred probe pending

However, the dependencies never seem to be resolved and the deferred probe is not happening.

That's the output with v0.3.3, the USB hardware is initialized straight away:

Thanks for the report. I'm not entirely sure what is going on here. It could be the Kernel version in 0.4.0 which is d1/all, rather than a specific tag which really should be done.

This may be related to Issue #17. Hopefully changes in v0.4.1 help with this.
