muto, do you know, how many A your 450W PSU can deliver on the 5V rail? With this mod, each U1 will draw at least 1A for 2.6 GHash/s as MansenP measured here.
This means your PSU should deliver at least 16A on the 5V rail, would personally feel comfortable with 20A.

40A @5V and 20A @ 12V (as far as I know the switch uses 12V), actually I saw that it is 550W PSU
Would test again with 10 Antminer's plugged into the Hub and check if they are running stable or not. In case they do, plug in additional Ants one by one, to check the critical mass for your PSU.
Just a thought.

It is the same problem even with one or two Sticks.
Do You use --icarus-options 115200:2:2 switch in Your start line?
For the actual version I did not. But have had this in my start line for 3.10.0. Adding it to the 3.9.0 doesn`t change anything
using BFGminer 3.10.0
this .bat will get you to 2.2Gh after that you need a soldering kit.
bfgminer.exe --set-device antminer:clock=x0981 --icarus-options 115200:2:2 --no-submit-stale -o http://stratum.bitcoin.cz:3333 -O worker:password -S antminer:all

I already have soldered sticks as descriped above. Your startup parameters got me about 25 Ghash, 0A81 gave 28 Ghash. 0B81 gave less.
Thanks for your help anyway.
