Dear Maintainer, Please enable CONFIG_PCIE_BRCMSTB on arm64. The Raspberry Pi 4 has a VL805 xhci controller connected to the PCIe bus on the SoC. All USB ports are connected to this controller. CONFIG_PCIE_BRCMSTB is therefore necessary for USB support. I tested rebuilding the current Debian 5.6 kernel in sid with just this change, and it is enough to enable the USB port on the RPi4: root@buster-rpi4:~# lspci -nn 00:00.0 PCI bridge [0604]: Broadcom Limited Device [14e4:2711] (rev 10) 01:00.0 USB controller [0c03]: VIA Technologies, Inc.
