Start with a short USB hub reset delay of 10ms. This can be enough for

The 2nd delay at the of the loop is completely removed. Since the delay
hasn't been long enough, a longer delay time of 200ms is assigned. And
will be used in the next loop round.
This hub reset handling is also used in the v4.4 Linux USB driver,
hub_port_reset().

(Tested with 1 USB SD card reader, 1 USB Ethernet dongle, 4 USB flash
drives, which IIRC includes some of the problematic devices that
triggered previous changes to the USB enumeration code in U-Boot)
