I have this dock since 6.16.9, I tried with the mainline repo as there are = lot of USB updates, the result is the same. These are the tests I did, but the same thing happens: - Other USB 3.0 ports. - Another hard disk. - Another motherboard. - Disable Udisks2. - Test all usbcore.xxxx and quirks options. - Mainline repo. Does not happen with: - USB 2.0 ports (No disconnections observed so far). - Another HD dock station. Device info: https://www.amazon.co.uk/POSUGEAR-External-Docking-Station-Support-Black/dp= /B0FNR4N6PM I am able to test patches if needed. --=20 You may reply to this email to add a comment.
