USB3.0 OTG port in device mode

Hi,

Does the UP Squared support USB3.0 OTG port in device mode? Wiki [1] says it supports only on UP , so I am just wondering what's the status on UP Squared.

Thanks

    Hi nagineni,

    We should release the next BIOS in a week or so.

    Hi, can you please confirm that current version of Up Squared is supporting USB OTG device mode ?
    I'm interested in impersonating USB storage device and/or HID devices in Ubuntu.

    Thank you.

    Hi raresh_p,

    USB OTG should be supported on UP2 from BIOS V2.1 onwards. See:

    Thank you for your comment, based on this I have ordered an UP Board.
    While in basic tests seemed to work with memtest ISOs (mounting it then having it available as USB Flash on Win 10 laptop) , now I have the "UDC error" :
    udc-core: couldn't find an available UDC - added [g_mass_storage] to list of pending drivers

    Is there any description how to specifically debug this and even check if the hardware is working ok?
    Or even how the BIOS setting should look in order to use UP Board as USB Device ?

    PS: Forgot to mention, I have the UP Board version with 2Gb memory and 16GB eMMC disk.

    Thank you.

    Hi @raresh_p ,

    Did you get that error when you connect your UP to your PC via USB OTG port, right?

    To be sure your OTG is working you must check in your PC if the board is available.

    Use dmesg | tail for example.
    You should see something like that:
