Hi,

i am working on an FX3 project. On my Laptop (debian buster) every thing works fine. when i connect the fx3 over usb 3 to a jetson tegra tx2 i get following error in dmesg:

[256143.872836] xhci-tegra 3530000.xhci: ERROR:unexpected command completion code 0x11.

[256143.880712] xhci-tegra 3530000.xhci: xhci_reset_bandwidth called for udev ffffffc1bf5f5800

[256143.889126] usb 2-1.1.1: can't set config

The tegra runs on ubuntu 16.04. L4T R28.2.0.

This only happens if i connect the fx3 to the usb 3 port.

Anyone an idea why this happens?

Sincerely Josef Sommerauer

Hi Josef,

Does your device any Isoc endpoint which asks for more bandwith? If that is the case, you can create an alternate setting with zero bandwidth/reduce the current bandwidth request in endpoint descriptor and try.

Also can you try it a Windows PC just to check device enumeration.
