Here is the steps with UMS on BPI-M2+ which is H3 board (USB is similar to H2+)

on target:
=> mmc list
SUNXI SD/MMC: 0
SUNXI SD/MMC: 1 (eMMC)
=> mmc dev 1
switch to partitions #0, OK
mmc1(part 0) is current device
=> ums 0 mmc 1
UMS: LUN 0, dev 1, hwpart 0, sector 0x0, count 0xe90000
\musb-hdrc: peripheral reset irq lost!

on host:
$ sudo dmesg

fastboot also look fine.
