Status in linux-raspi2 package in Ubuntu:
Confirmed
Status in linux-raspi2 source package in Bionic:
Confirmed
Bug description:
[Impact]
After updating the firmware to the latest version from
github.com/raspberry/firmware, the NIC on a PI 3B+ running Bionic is
no longer recognized/initialized. In fact, no USB devices are
discovered at all.

[Test Case]
Pull latest firmware from github.com/raspberry/firmware, compile
LAN78xx module into the kernel, boot on a PI 3B+.
[Fix]
Backport commit d903e18191d3 ("usb: dwc_otg: Clean up interrupt
claiming code") from upstream raspberry/linux rpi-4.19.y.
[Regression Potential]
Low. Modifications are isolated to the dwc_otg driver. Patches are
cherry picks or simple backports from upstream rpi-4.19.y.
