3.07 → 3.10 turned bad in my end 
With 3.07 I was able to connect power, display, network, keyboard and mouse with my loved WD D50 with a single cable.
After updating to 3.10 that link becam totall unstable resulting in sporadic losses every 5 minutes. God knows what has been changed, but I am now forced to plug in a separate power supply. That is not the idea of USB4, I don’t want to mess with my desk. Opened a ticket for this and got a confirmation, that this other cable is the work around. Nothing about when this get’s fixed as it is obviously physically possible (remember: It worked with 3.07!).
Thank you for the second cable!
