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.
Re: Hi Speed vs. Full Speed on the Atom proc. board
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?
