This can be because UMS is not DM aware?

This test is on 2018.09-rc2 with UMS enabled.
With your patch, I get this dmesg on the host:
[20121.718226] usb 1-4-port4: Cannot enable. Maybe the USB cable is bad? [20122.578151] usb 1-4-port4: Cannot enable. Maybe the USB cable is bad?

[20124.602190] usb 1-4-port4: unable to enumerate USB device
u-boot console is the same, including loading the gadget:
Allwinner mUSB OTG (Peripheral)
If you tell me how you tested USB Gadget to work, I will reproduce your test locally to confirm the issue.
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!

fastboot also look fine.
