I'm now running a 2019-09-26-raspbian-buster-lite.img with 4.19.75-v7l+ kernel and /dev/mmcblk0* are correctly populated. pi@raspberrypi:~ $ dmesg | grep firmware [ 0.090391] raspberrypi-firmware soc:firmware: Attached to firmware from 2019-09-24 17:34, variant start [ 0.100110] raspberrypi-firmware soc:firmware: Firmware hash is cd3add54955f8fa065b414d8fc07c525e7ddffc8 [ 4.322157] vc4-drm soc:gpu: bound fe600000.firmwarekms (ops vc4_fkms_ops [vc4]) But I've also set total_mem=1024 to be on the safe side, so it may be related. I'll try to build an initramfs with BTRFS for this kernel and switch back to Ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848703 Title: Raspberry Pi 4 - USB Bus not detecting any devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1848703/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
