Although it didn't make it to the list (because we don't allow  
attachments larger than 40 kB), I received it directly.

That's a fairly short report descriptor for a HID PDC device. It is a  
valid one though, but it just doesn't have a lot of reports in it. I  
think we already support most of it as it is and that it doesn't  
report battery voltage. The only report that comes close is

This could be the battery voltage times 100, but in that case the  
value is surprisingly low (a few tenths of a second before, it  
reported a fully charged battery). It could also mean the input or  
output voltage (or something completely unrelated). There is no way to  
tell without digging deeper into this.

The remainder of the reports are either already supported or vendor  
specific ones. If you're willing to work with us, we might attempt to  
figure out what these mean. Please let us know if you're able to do so  
(this will probably require frequent updates of the driver with lot of  
debugging enabled) and we'll continue on the development mailing list.

Best regards, Arjen
