Oops, worrying results:

    0.334659	Can't retrieve Report 17: Value too large for defined data type
    0.334690	Path: UPS.PowerSummary.ConfigVoltage, Type: Feature,

The following reports are also suspicious:

    0.338612	Path: UPS.PowerSummary.Voltage, Type: Feature, ReportID:  
0x12, Offset: 0, Size: 16, Value: 212.000000
    0.369618	Path: UPS.Battery.Voltage, Type: Feature, ReportID: 0x1a,  
Offset: 0, Size: 16, Value: 212.000000
    0.380612	Path: UPS.Input.Voltage, Type: Feature, ReportID: 0x1d,  
Offset: 0, Size: 16, Value: 212.000000
    0.395605	Path: UPS.Output.Voltage, Type: Feature, ReportID: 0x21,  
Offset: 0, Size: 16, Value: 212.000000

I really doubt the above values are indeed identical.

Could you do the same, but now at debug level 3 (-DDD). I would like  
to see the raw dump of the report descriptor too, to see where the  
error is. My guess is that there is something wrong with the contents  
of the report descriptor, that might allocate too little room for the  
reports.

Best regards, Arjen
