IO16787: NON-IBM USB DEVICE FAILS FLASH ON 4690 ENHANCED

 

APAR status

  • Closed as program error.

Error description

  • Customer reported their non-IBM USB handheld scanner flashes
    successfully on V6R2 4690 Classic terminals but fails to flash
    on the same level OS running Enhanced.  They had modified their
    ADXUSBUF.dat file to cause the handheld scanner to flash to a
    newer firmware but noted that on Enhanced the scanner would
    never come online after a terminal reload. Once loaded, if they
    hotplugged the USB scanner it would successfully come online and
    continue to operate until the next time the lane was reloaded.
    

Local fix

Problem summary

  •  Scanner device is unable to handle increase
    USB packet throughput provided by Enhanced OS4690 which resulted
    in the device hanging during flash process.
    

Problem conclusion

  • Code change made allowing the user to specify a logical name to
    disable the USB bandwidth reclamation feature utilized in OS4690
    Enhanced terminals and reduce the USB packet throughput to the
    same level currently in OS4690 Classic.   The logical name
    ADXURBNO is defined to reduce the throughput which enabled the
    scanner to be flashed.
    IMPORTANT NOTE:  Due to hardware differences, logical
    name ADXURBNO has NO effect (will NOT reduce the
    USB traffic speed) on 4900-7x5 and 4810-35x machines.
