If I try to re-attach the laptop to the docking station nothing change, the ports (docking and laptop) are still disconnected, the hdmi/lan/power is working good. Sometimes it happens also when the laptop is docked and I'm working. The issue seems similar of the bug 1766076: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1766076 but here no thunderbolt, it's a ryzen cpu. As written in the bug 1766076, the only way to have the USB in working condition is unbinding/binding the xhci or using the unit/systemd workaround described on post 83 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1766076/comments/83) with some modification, sometimes is still not working at all. The issue is present on Ubuntu 19.10 (see below the logs), on Ubuntu 18.04 (with kernel 4.x or 5.0 mainline by ubuntu, 5.2 and 5.4 debs installed from kernel.org) and on Fedora 31 too. In Windows everything is working fine. The bios and firmware of the docking station are updated to the last one (1 month ago).
