on my OrangePi3 I get this upon power up (with an usb3 flash drive as well as a SD card reader):

A second retry makes the usb@5200000 pass though.
May be related, but sometimes it can then boot off the usb device, but sometimes I get this:
=> setenv boot_targets usb0 => boot
Device 0: Vendor: Generic- Rev: 1.00 Prod: USB3.0 CRW -SD Type: Removable Hard Disk Capacity: 1876.0 MB = 1.8 GB (3842048 x 512) ... is now current device Scanning usb 0:1...

And sometimes it get further but then fails shortly after:
=> setenv boot_targets usb0 => boot
