    Hello everyone,

    I wanted to do something similar, modify NXP Host Lite for typical USB mouse support. But unfortunately I have a problem during very early stage, when Host sends SETUP Packet, mouse does not respond.
    The variable HOST_TDControlStatus at the end of Host_ProcessTD function has value 5 which corresponding DeviceNotResponding Condition Code I suppose.

    As well as I connect massive storage device, the variable has NOERROR code. Should I do something more for mouse support?

    English is not my native language, so forgive me for any grammar mistakes :)

    Regards
