USB-ethernet under linux rt

[Ehlert]

Does anyone have experience with usb to ethernet dongles on at linux RT target?

Would it show up in MAX like other ethernet ports?

yes, but I still having issues.

the adapter has a ASIX AX88772 chipset which be supported, but running the dmesg cmd gives:

usb 1-1: new high-speed USB device number 3 using xhci_hcd

It should appear with an IP of 172.22.11.2

What RIO are you using?

What version of the NI-RIO driver do you have installed?

[Ehlert]

I am using a CVS1459rt with NI-RIO 14.0.1

Does the "ip address show" command in SSH show the USB Ethernet adapter as an Ethernet interface?

Does max see the additional interface?

[Ehlert]

I dont see it in MAX, and I can try the SSH command tomorrow.

I don't see the Asix driver when I do the lsmod command

Sorry I mistyped the command, it's "ip addr show"

It's definitely not a good sign if lsmod doesn't show it 😕

Can you try any other adapters?

[Ehlert]

I ordered a bunch more (8 different) that will arrive tomorrow - hopefully I will have more luck with one of those

For reasons unknown to me, the x64 kernel used by the cRIO 903x and CVS 1459RT do not have USB Ethernet dongle support enabled, unlike the one used on ARM targets like the cRIO 9068 and myRIO.
