Using a different USB adaptor with LIbreElec and the Raspberry Pi

1st Official Post

    Hi all,

    I'm attempting to use a faster WiFi USB dongle with my Pi. However, I'm struggling to configure it. Can anyone advise the best way, please?

    There are a couple of points that have been asked for, previously, below.

    Code
    dmesg | pastebinit: http://ix.io/2RAn

lsusb | pastebinit:http://ix.io/2RAt

    Is this that can be done with an add-on or is it command line?


    Let me know, thanks.

    A.

    Thanks. I ran:

    # pastekodi

    error=1 error_msg="Command not registered"

    Use 'vcgencmd commands' to get a list of commands

    I hope that helps? THe USB key seems prett generic.

    That being said, I also purchased a LinkSys USB dongle which worked out of the box - I just needed to add the local Wi-Fi network and bingo. So, there are actually 3 wireless devices on the PI. The LinkSys works as does the on-board Wi-Fi chip, but this generic USB dongle still refuses, and that's the one I need to sort. :)


    Thanks!

    Adam.

    Seems like your WiFi USB dongle is detected as an Ethernet device:

    So I think the driver is missing for that dongle. Use a different one.

    It's:

    Code
    Apr 11 16:28:37 LibreELEC kernel: usb 1-1.5: new high-speed USB device number 6 using dwc_otg
Apr 11 16:28:37 LibreELEC kernel: usb 1-1.5: New USB device found, idVendor=0bda, idProduct=c811, bcdDevice= 2.00
Apr 11 16:28:37 LibreELEC kernel: usb 1-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3
Apr 11 16:28:37 LibreELEC kernel: usb 1-1.5: Product: 802.11ac NIC
Apr 11 16:28:37 LibreELEC kernel: usb 1-1.5: Manufacturer: Realtek
Apr 11 16:28:37 LibreELEC kernel: usb 1-1.5: SerialNumber: 123456

    But it is unlikely that needed rtl8821CU driver not included in the kernel source will be added.

    Da Flex What do i miss in the logs?

    The log snippet I've been posted. lsusb says

    Code
    Bus 001 Device 005: ID 0bda:c811 Realtek Semiconductor Corp. Bus 001 Device 004: ID 25a7:1047
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter

    but the user has no Ethernet adapter attached (makes no sense together with WiFi dongle).

    So I'm thinking both entries are pointing to the same USB device.

    The device is a a RPI 3B.

    Code
    Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub

    are the standard "internal" RPI Ethernet and WIFI adapters attached via USB.

    It is visible:

    Code
    Bus 001 Device 005: ID 0bda:c811 Realtek Semiconductor Corp.

    But the driver rtl8821CU is not (and most likely will not be) included into LE.

    mglae I'm confused now. On my RPi3B+ the lsusb with no attached USB devices is:

    Quote

    Bus 001 Device 004: ID 0424:7800 Microchip Technology, Inc. (formerly SMSC)

    Bus 001 Device 003: ID 0424:2514 Microchip Technology, Inc. (formerly SMSC) USB 2.0 Hub

    Bus 001 Device 002: ID 0424:2514 Microchip Technology, Inc. (formerly SMSC) USB 2.0 Hub

    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

    No Ethernet device on the list. Are you saying RPi3B and RPi3B+ handle internal sub-devices differently?

    From the announcement the major improvements of the 3B+ are a slightly increase in CPU speed, gigabit ethernet and ac WIFI.

    The new ethernet chip is still attached via USB while WIFI is connected via SDIO.

    Use lsusb -t or lsusb -v to list the USB classes.
