Disabling the autosuspend from the USB device fixed the problem. However, I did not want to disable it for all USB devices, so I added an udev rule:
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="214b", ATTR{idProduct}=="7000", ATTR{product}=="USB2.0 HUB", TEST=="power/control", ATTR{power/control}:="on" On Windows, the USB power saving is enabled but this does not happen. Maybe Windows has a quirk configured for this device already? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904953 Title: USB2.0 HUB only works after an USB device is connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904953/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
