Yes, to reproduce this issue on U-Boot master, just need to apply this
series plus Marek's fix:
https://lore.kernel.org/u-boot/CAOMZO5Cid5eck=ahiowbAKOjaQNzOORNLU-PxadkMFSEnqvNmg@mail.gmail.com/T/#t

It looks like some clock-related issue:

u-boot=> ums 0 mmc 1
UMS: LUN 0, dev mmc 1, hwpart 0, sector 0x0, count 0x3b72400
CTRL+C - Operation aborted
clk usb_bus already disabled

After issuing CTRL+C, dmesg on the host PC shows lots of USB failures.

If you have any suggestions, please let me know.

Thanks
