#67170 — Bug#961459: linux-signed-arm64: option that might support raspberry pi 4 usb

Package: linux-signed-arm64
Version: 5.7~rc5-1~exp1

At least from this comment,

  https://github.com/lategoodbye/rpi-zero/issues/43#issuecomment-611780458

it looks like we might need

  CONFIG_PCIE_BRCMSTB=m

to allow USB to work on the pi 4.  I can verify that 5.7~rc5-1~exp1
boots fine on one, all the way to a tt1 login, but there appears to be
no USB power, i.e. a keyboard or mouse plugged in does not respond, and
the normal power leds on the keboard and mouse don't light.

If I get a chance and figure out how, I can try to build a local kernel
with that option and test it, or I could fairly quickly test any version
uploaded somewhere like experimental.

Thanks

I have done this, and verified that the USB ports work if
CONFIG_PCIE_BRCMSTB is enabled.  See
