[Bug 1509896] Re: IPMI USB SCSI endpoint discovery can fail on OpenPower machines

[Frédéric Bonnard]

Verification successfully done on Trusty with : ipmitool
1.8.13-1ubuntu0.6

According to the bug fix in git :
----
    The current USB plugin doesn't find my IPMI channel:
    
      # ipmitool -I usb mc info
      Error in USB session setup
    
      Unable to setup interface usb
      Error loading interface usb
    
    This is beacuse I have more than 8 scsi-generic devices that identify
    as AMI:
    
      # grep -c ^AMI /proc/scsi/sg/device_strs
      13
