reply Mark Dunn, The kernel you wget and installed already included the patch for 3093, so in theory, after installed the new kernel, the usb should work with 4G ram. Please verify the kernel you are running is the new kernel, please upload the output of 'uname -a' and dmesg. -- 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
