• Issue w/ Booting from USB & Fix

    USB connector.

    Neat right? Well, not so much... the SSD to USB connector that they
    used has cheap UAS and after copying over my SDcard to the SSD it
    wouldn't boot normally.

    I was getting fails by systemctl all thru the boot process, and it
    would end at a black screen with just a cursor - or, it sometimes would
    get me to a text linux login prompt. Neither were my normal GUI that it
    should have booted to.

    Long story short, if you're experiencing this with an SSD to USB
    connector, OR if you're simply experiencing very low data rates while
    on SSD over USB, you need to read this sticky that I ended up finding
    after hours of research:

    STICKY: If you have a Raspberry Pi 4 and are getting bad speeds
    transferring data to/from USB3.0 SSDs, read this

    Seems that some Jmicron, and other SSD to USB cables are inferior and
    are finicky with RPi 4's. So, I had to do a 'mesg' on the SSD and get
    some part numbers specific to my cable and edit the cmdline.txt file on
    /boot with a usb.quirks=xxxx:xxxx:b line... however, this disables UAS which.... I can't understand, other than being cheap and stupid, why
    NesPi would use this cable! So stupid, if I'm intending to use this
    case as a USB Boot device. Derp!!!

    Maybe they just thought it would be for mass-storage, but I wanted to
    BOOT to it. Anyway, I'll buy a good connector and save this NesPi case
    for a diffferent application... but how stupid is that.

    Anyway, for anyone doing USB boot on a Raspberry Pi 4, with issues...
    this might be a great place to start - and save you tons of time. :P

    After I editing the cmdline.txt, the system boots directly into my GUI
    and I'm getting 270,000 sequentials, 5500read and 5000write speeds.

    :shrug:
