  • USB CDC communication gives stall packet in PC side randomly

    HI,

    We are using the Segger emUSB CDC with embOS in our product, with LPC2478. on continuous use of the system we are seeing sometimes the PC side gets in packet stall and the communication stops. If you have seen these issue can you let us know what can be probable cause of this issue. We are using the blocking call of USB_CDC_Write to transfer the data. the System side keeps on running.and in order to restore the communication we had to disconnect and connect back again.

    Any input will be welcomed...

    Regards
    :love: Satya
