[Nut-upsdev] Re: PowerCom USB units...

[Eric Ashley]

I did actually test descriptor 0 with indices 0 through 8 and got the
following:

./get_descriptor 002 008 1 0 0 128 0 0
Can't get endpoint 128 descriptor 0x00 index 0: error sending control
message: Broken pipe

Just to make sure, I just checked again working all the way up to index
31, with all returning "Broken pipe."  My most interesting data was for
descriptor 0x21 and 0x22, though I can't make any sense of the bytes
returned.  Hopefully, PowerCom will come across with the data. 
Otherwise I'll USBSNOOP the Windoze interface to determine what it's
processing.

When these units return a value on a particular descriptor, except
0x03, will return the exact same data no matter what index I specify. 
The same 18 bytes is returned on descriptor 1 index 0 or index 128.

Thanks again,
Eric
