Name the tree/revision/version:
OpenWrt v18.06.2 and later (tested v18.06.8, master at 1fb3c00)

Name the affected device:
ZyXEL Keenetic

What does it not do that it should do:
USB port is not working.

Steps to reproduce:

  1. Build and install OpenWrt v18.06.2 or later with appropriate kmods and their dependencies:
    kmod-usb-dwc2
    kmod-usb-storage
    kmod-fs-vfat

  2. Boot.

  3. Insert a USB flash drive. There is no /dev/sd* device to mount, no new usb related messages in dmesg.
    Just for test, plug in a USB optical mouse, LED does not light.

What you have already done to workaround/fix the problem:
On v18.06.1 USB works, files from the flash drive ara accessible, LED in USB optical mouse is on, corresponding dmesg messages appear.

Any additional info you think is important:
bootlogs with USB flash drive attached:
18.06.1-bootlog.txt - 18.06.1 (flashed)
18.06.2-bootlog.txt - 18.06.2 (initramfs-kernel loaded from tftp)
master-bootlog.txt - master (initramfs-kernel loaded from tftp)

patches to use full 8MB flash applied to install packages:

This bug looks very similar to FS#2839, both devices are based on Ralink RT3052.

Perhaps it can be fixed by the method proposed in bug FS#2738.

I built 18.06.2 and master at 91c61aa for ZyXEL Keenetic with 0032-USB-dwc2-add-device_reset.patch removed as described in FS#2738 and USB works with a USB flash drive.

FS#2473 is about the same problem on another device based on Ralink rt305x.

USB does not work in master at 35f208d built with testing kernel 5.4 with or without 0032-USB-dwc2-add-device_reset.patch.
Boot log attached.
