Hi Speed vs. Full Speed on the Atom proc. board

[Tom]

Good morning,
   
     I discovered this morning that USB ports 7 and 8 on the Atom processor board only seem to recognize Hi Speed (480Mb/s) connections, like the uEye cameras, and not Full Speed devices like the Hokoyu laser scanner.  I just finished installing Ubuntu 10.04LTS, and I haven't touched the BIOS.  

     Has this happened to anyone else?  My Hokuyo cable is designed to plug into P7, and changing that would be pain.

Thanks,

Hi Tom,

yes P7 and P8 support only usb 2.0 devices see:

Thanks.  It would seem the USB2.0 spec is a bit unclear on the "full" vs. "high" speed issue, since the lidar claims to use a USB2.0 Full Speed interface.  It's possible Hokuyo's wrong about their chipset, but could this be a Linux driver issue?  

Thanks again,

-Tom
