SIO2USB timing problems with BlackBox and US Doubler routine

Did anyone yet test Sio2USB with the BlackBox?
I'm having serious timing problems with SIO2USB on HighSpeed.
I have the feeling it does not understand the US DOUBLER commands 100% right. I have related issues with SpartaDos 3.3b
With SpartaDOS 3.3a and QMEG there are no highspeed SIO timing problems with Sio2USB.
With BlackBox and Sio2IDE, SIO2SD and APE there are no timing issues on the highspeed SIO. Only with Sio2USB.
I hope someone could confirm the same test results.
I made 4 movies in which you can hear the timing issue with BlackBox. It is booting a simple DOS 2.5 ATR. With Sio2USB you hear the data flow is not steady. It goes like
Trrrr prt prt Trrrrrrrrr prt prt Trrrrrrrr prt Trrrrrrr prt prt....
It should go like:
Trrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr.
Those "prt prt" timing trouble is not caused by a Flash-load-into-memory lag, because with Qmeg and SIO2USB this problem does not exist.
Please check my page (http://www.inspiration-soft.com) on the Sio2USB section for more info, and the movies.
Thanks
