There is also an attached Word document covering the UPSC / UPSCMD / UPSRW information from the specific UPS systems. Let me know if this is adequate to get our additional HID compatible products added to the NUT HCL listing.

Mr. Cobb,

Thanks, that is definitely enough for us to get started. I think we have some additional homework to figure out a better way to represent all of this information on the NUT website, but for now, we can point users to the documents you provided if they need details beyond the basic model/driver information that would be added to the HCL.

A couple of questions:

 * For the HID units, is the four-digit "Protocol" always equal to the USB Product ID? (This was not the case with some of the non-HID models, so I just want to be sure. If the only non-HID USB ID is 09ae:0001, we can adjust our drivers' detection algorithms.)

 * Some of the voltages look out-of-range. For instance, on the SMART1500LCDT, the battery voltage is listed as 0.0 (using NUT 2.6.3). This looks similar to the case I mentioned earlier[1], and in order to try and fix that, it would be good to know if this is limited to a specific protocol number, or if protocol 3016 might be patched in the future.

 * Were the variables like ups.delay.shutdown verified to be mapped correctly in NUT? I see that they read back, but there is certainly a possibility that we are not mapping the names to the proper HID usage IDs. "Mike." asked a little about this particular variable earlier in the thread, and this seems to be one of the more important configuration knobs that people want to adjust.
