20559RE: [perseus_SDR] USB3 and Back Compatibility
- Jun 2, 2013
Wow…it works! Changing XHCI Pre-Boot Mode from Auto to Disabled in the BIOS of my ASUS laptop fixed the problem and now the Perseus works! Thanks for the tip, Ken.
Very interesting. Those sound like the same symptoms I was experiencing on a Toshiba laptop last week. Hope this settles down in future versions of Windows and/or Perseus software. We can't keep trying one laptop after another until we find one that works... 73, Tim

I have been able to get USB 3 to work with the Perseus on a couple of Win 8 Asus laptops by changing a bios setting.
One of these machines only has USB 3 ports.
Before I did this only HF Span would work correctly. After the change the 4.0c worked properly. I do not know what bios
settings others will have available but I would suggest some experimentation in the USB bios settings if you do not have the
same settings available to you as on my machines. How you access the bios is machine and sometimes operating system specific
so if you do not know how to do this already you will have to do some research. For most Win 8 machines you can get to the
bios through advanced start-up. Google how to access the bios for your machine should get you all the info you need.
When you get to the USB configuration in the Bios change XHCI Pre-Boot Mode from Auto to Disabled. Save the change and exit the bios utility.
This was all I did to get the Perseus up and going with 4.0C on USB 3.0.
I hope this helps.
