PinePhone A64: No working USB controllers about jumpdrive

Running source /init_functions.sh and then setup_usb_configfs in the shell (if Jumpdrive reaches it) raises the fatal error Couldn't create /config/usb_gadget/g1. Trying to escape that with ^Z briefly shows the reason:

Setting up an USB gadget through configfs...

  Couldn't create /config/usb_gadget/g1

sh: write error: Device or resource busy

and then raises another fatal error (Couldn't write to UDC), but I can escape that one with ^Z and get back to the shell.

Weirdly enough, Jumpdrive works fine when booted from megi's multi-boot image flashed to a microSD card. It then connects as an Ethernet adapter and two block devices (eMMC and microSD), as expected.
