Internal connectivity of USB ports
Posted: Thu Oct 25, 2012 5:14 pm
Hi,
I have previously been working with the Fit-PC2i, and I notice on that platform that when I run lsusb with a bunch of flash drives plugged in, I see:
It looks like all four external ports on the 2i are connected to an internal hub on Bus 001. This is a problem as we are hoping to add multiple devices each requiring full bandwidth (camera, lidar, high power wlan adapter, etc).
Is the Fit-PC3 similar? How many buses are there across the 8 USB ports on the Fit-PC3?
Thanks,
Mike
