USB Host dwcotg:irq 39 disabled in 32 bit mode

[imgaolong]

Compiled in 32 bit mode with default config file bcm2709_defconfig, the usb host initialization failed. And the usb mouse and keyboard will not work.

I am using Raspberry Pi 3B+, and the distribution of Ubuntu Mate 18.04, and gcc 5.4 for arm-linux-gnueabihf-. The kernel branch is rpi-4.19.y.

dmesg shows:

The kernel branch is rpi-4.19.y.

[ 12.706592] CPU: 0 PID: 31 Comm: kworker/0:1 Not tainted 4.15.0-1032-raspi2

So 4.19 or 4.15?

[imgaolong]

It is a mistake, it is log message of Ubuntu Mate, I forget to switch to the new kernel of 4.19.

With dwc otg, the usb of P3B+ is working well, just as in 64 bit mode.
