    HP LaserJet printer not recognized on Ubuntu 20.04

    HPLIP installed. Tried multiple usb printer cables, different ports.

    lsusb lists all devices, but not the printer (HP LaserJet Pro MFP M148fdw). With HP Device Manager no usb devices are detected.

    HP setup with HP Device Manager, Terminal has been showing the following:
    Searching... (bus=usb, search=(None), desc=0)
    error: No devices found on bus: usb

    Have you tried in another computer? And other USB devices in that one?

    Then why didn't you reach the obvious conclusion the printer is defective yet?

    Is it that obvious? Brand new, straight out the box. As a newbie I figured we are looking at a software issue.

    Yes, it could be a (very rare) software issue. Printers may not work due to a missing or non-working driver. However, in those cases, the hardware would still be detected by lsusb.
    When it isn't detected/listed in lsusb the printer could still be fine and the problem be in the USB ports, hence the second part of my question above.
    Now, if other USB devices works in the same computer and the printer isn't detected in another computer then it become bloody obvious where the problem is.

    The results of the troubleshooting you already did should have been posted in the OP. That would have saved us this unproductive back and forth.

    If it's brand new ask for an under warranty replacement.

    That's a possibility. You appear to have done all the right things - changing cables etc - and lsusb doesn't show anything. How do you fancy setting up a wireless connection with the LaserJet?

    Incidentally: you do not need HPLIP with your device.
