    Unhappy gs_setup: unknown request


    hi,
    I have been communicating on My linux embedded board(Running linux-arm).
    I have been using gadget-serial driver for transferring and receiving data from the WINDOWS machine running some application.

    Now when the linux -arm port does not have some data and windows API tries to access the Linux serial port for that data,i get the following log on LInux side board.:

    gs_setup: unknown standard request, type=02, request=01, value=0000, index=0082, length=0
    s3c_ep0_setup: --> ERROR: gadget setup FAILED (stalling), setup returned -95
    gs_setup: unknown standard request, type=02, request=01, value=0000, index=0082, length=0
    s3c_ep0_setup: --> ERROR: gadget setup FAILED (stalling), setup returned -95


    This log hinders further communication.Can you please tell some solution for this.


    Please its very urgent.
    Thanks

    Hi Ashutosh,

    gs_setup returns the size of the data sent to the host, or a negative error number. As it dosent has any data that's why it returns negitave number
