    hello.

    I have three LP, and I would like to use for kinect v2 at window 10.
    When I bought first LP which z8300 4g 64g, it pretty good working.
    The z8300 LP can connect usb 3.0 memory stick, and kinect v2.
    And I bought again two LP which z8350 4g 64g.

    However, it cannot connect usb3.0 memory stick and kinect v2.
    When i connect usb3.0, it did not show up the device at device manager.
    Also, i tried reinstall Win 10, but it just jump up install step, although i followed LP win 10 install tutorial at trouble shooting.

    One of the LP, it can boot up. When power connect to LP, it show up the blue light, and blinking. but it does not turn off the RED led, even though i did not set up auto booting.

    So, if i missed up some step,plz help me any comment is good for me.

    thank you.

    I have a similar problem,

    All 3 USB connections work in 2.0 mode, BUT the 3.0 functionality does not. I updated the drivers and reinstalled Windows with no avail.
    The 3.0 functionality seems to have worked only two times. In both instances a 3.0 thumb drive was recognized, but once removed and reinserted it was no longer seen by the LP. Both instances seemed to be random and were after a restart.

    Is this a potential hardware issue?

    Dear both,

    This problem only happens on one LattePanda v1.1 production batch and it's fixed on the latest bios and driver upgraded from LattePanda official github.

    Please make sure that you've tried to upgrade the bios and right driver from here already:
    https://github.com/LattePandaTeam/Latte ... 0-Software

    If it still didn't work, let me know where did you purchase the LattePanda, we will provide the right after-sales solution to you here. ;)

    Hi @LattePanda

    I'm also having issues with USB 3.0 functionality. I am trying to reflash the bios, but I am unable to follow the instructions (https://github.com/LattePandaTeam/Latte ... aster/Bios). Here is what I've done:
    1. Formatted a USB drive to FAT-32
      (Format your U-disk to FAT32)
    2. Downloaded the BIOS .zip file from GitHub (https://github.com/LattePandaTeam/Latte ... %20version)
      *the information on my side sticker states: S7CR110-CC55D MID / Z8350
    3. Copied the entire contents of the .zip file onto the USB drive
      (Copy the right BIOS files directly to root of the USB flash disk)
    4. Powered down the LP
    5. Removed and re-inserted the micro USB (with the USB drive containing the contents of the .zip file inserted into the USB 3.0 port)
      (Plug the U-disk in USB host)
    6. Pressed the power button once the red LED went off to boot the LP
      (Plugin the MicroUSB cable and power on the system)
    (Wait the refreshing the BIOS automatically until returning "fs1:>" (Check the “)
    The LP booted directly to Windows and I was not able to update the bios

    If you could please point out which step was not properly followed, that would be appreciated.

    Dear flyingpoutine,

    I think the only thing you may try is just changing the boot option from hardware disk to USB boot.
    Here's a simple guide:
    1. Press "ESC" once powering on the device
    2. Enter BIOS mode and choose Boot on the MENU
    3. Set "boot option" to external USB storage. Notice to plugin your U-disk.
    4. Save and restarting the system.

    Let me know if it works for you. I can help to attach more pictures if you think it's still no clear enough. ;)
    Look forward to your updates!
    Enjoy Tinkering with LattePanda ! :lol:

    Hi LattePanda,

    That did it! Thanks for the clarification.

    For those who may come after, here's what I did:
    1. Formatted a USB drive to FAT-32
      (Format your U-disk to FAT32)
    2. Downloaded the BIOS .zip file from GitHub (https://github.com/LattePandaTeam/Latte ... %20version)
      *the information on my side sticker states: S7CR110-CC55D MID / Z8350
      ** You'll have to select the proper BIOS for your LP based on the info found on your sticker, as outlined here: https://github.com/LattePandaTeam/Latte ... aster/Bios
    3. Copied the entire contents of the .zip file onto the USB drive
      (Copy the right BIOS files directly to root of the USB flash disk)
    4. Powered down the LP
    5. Removed and re-inserted the micro USB (with the USB drive containing the contents of the .zip file inserted into the USB 3.0 port)
      (Plug the U-disk in USB host)
    6. Pressed the power button once the red LED went off to boot the LP
      (Plugin the MicroUSB cable and power on the system)
    7. Pressed the ESC key repeatedly until entering the BIOS menu
    8. Selected the Boot menu option
    9. Changed the boot order to boot from USB first
    10. Saved and exited
    11. Rebooted the system to boot from USB disk
    12. Bios updated as per instructions
    13. Once the update completed (roughly 5 minutes) removed the USB drive and pressed the reset key on the LP
    The system came back up and my USB port now works in USB 3.0 mode. It did however change my screen resolution back to the recommended/default settings. Simply reverted the settings to how I had them before and I was on my way!

    This is great!
    And I've managed to add a new FAQ part on the Github tutorial page.
    Hyperlink this forum topic to help other people who may have similar problems in the future.
    Appreciate your much clearer guidance for all steps. ;)

    I have the same USB3 problem - not recognizing USB drives. Your disclaimer states
    "Disclaimer:
    Please note that this is a beta version of the bios which is still undergoing final testing before its official release.
    This version is test-only, so please confirm with us before you reflash the bios.
    Reflashing without notifying us can put your board in a state of no return and void your warranty.
    Ensure that you have saved the Windows product key code and you have an SPI chip programmer to reflash the bios at hardware level"

    Why do I need a SPI chip programmer?
