Well I relay brought up my problem with my 452e...
I just want to ask since 400e and 450e needs firmware...maybe 452e needs 
firmware too (for whatever reason maybe only on ppc architecture) and 
thats my problem? Could that be possible? If yes how to I get firmware 
for 452e and look if that solves my problem?
Well if I look at dmesg after plug in my 452e the last line was:

usbcore: registered new interface driver dvb-usb-tt-connect-s2-3600-01.fw

looks like some firmware is loading maybe thats a wrong one, since I buyed my 452e last month there could be an little change to the hardware so that dvb-usb-tt-connect-s2-3600-01.fw is not workin anymore.
However I have no clue how to extract the firmware the right way so if that could do someone for me I would be very thankful

Michael
