New ASIX USB3 product

New ASIX USB3 product

[Jérôme Poulin]

I just bought a gigabit ethernet USB3 adapter, it is a StarTech
USB31000S adapter and it does not seem to be un ASIX product database
yet.

I tried binding it with the driver and it returns error -32, what does
this mean?

Here is the dmesg output:

The AX88179 device is not yet supported by the mainline asix drivers. 
You could try to use the driver from the ASIX website [1]. Or you could 
compare this driver to the code in drivers/net/usb/a* and see if one of 
these drivers would work for the AX88179 and add an entry for the 
AX88179 in usb_device_id struct in asix_devices.c.
