Hi,
I am trying to connect a USB to ethernet adapter(ASIX AX88XXX) to the USB OTG1 port on the imx6sx custom board.
I have setup the device tree for the usbotg1 as below, I have enabled the USB net driver CONFIG_USB_NET_AX8817X along with USB_USBNET. but when I plug in the device, the relevant driver is not probed instead the usb device is just populated as Bus 001 Device 001: ID 1d6b:0002 as below: am I missing any other driver or config that is preventing the driver from getting probed?
Listing when the device is plugged in:
# ci_hdrc ci_hdrc.0: EHCI Host Controller
ci_hdrc ci_hdrc.0: new USB bus registered, assigned bus number 2
ci_hdrc ci_hdrc.0: USB 2.0 started, EHCI 1.00
usb usb2: New USB device found, idVendor=1d6b, idProduct=0002
usb usb2: New USB device strings: Mfr=3, Product=2, SerialNumber=1
usb usb2: Product: EHCI Host Controller
