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
So we end up hitting the max in FindG2CDROM, and abort without finding
the actual IPMI endpoint (on my system, this is /dev/sg11).
This change bumps that maximum up to 16.
However, that means we hit another bug in scsiProbeNew, where if
we hit the end of the file without completely filling the array,
we return with an error. This change handles the EOF condition
gracefully instead.
Also, fp is never going to become NULL; we don't need to check for that
condition.

This feature request is for adding support for USB Medium as an interface in
IPMITool. AMI BMC (OEM feature) provides Virtual USB devices in the host as
part of its feature list. IPMITool can use this 'Virtual USB device' as a
medium for Inband communication with BMC.
Just like any other interface, use can just give 'ipmitool -I usb xxxx' to
communicate with the BMC via USB Interface.
