Post Internal connectivity of USB ports
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:

Code:
administrator@cpr-test-machine:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter
Bus 001 Device 003: ID 0930:6545 Toshiba Corp. Kingston DataTraveler 102 Flash Drive / HEMA Flash Drive 2 GB / PNY Attache 4GB Stick
Bus 001 Device 004: ID 0930:6545 Toshiba Corp. Kingston DataTraveler 102 Flash Drive / HEMA Flash Drive 2 GB / PNY Attache 4GB Stick
Bus 001 Device 009: ID 0930:6545 Toshiba Corp. Kingston DataTraveler 102 Flash Drive / HEMA Flash Drive 2 GB / PNY Attache 4GB Stick
Bus 001 Device 007: ID 0930:6545 Toshiba Corp. Kingston DataTraveler 102 Flash Drive / HEMA Flash Drive 2 GB / PNY Attache 4GB Stick


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

Hello Mike

On Fit-PC3 you have a 3 USB2 buses, and a 1 USB3 bus.
