I should probably just ask for 60 seconds in the future :-)

There are nearly 30 seconds' worth of "Quick update..." lines, but because the 30-second timer doesn't start until after everything is initialized (takes a few seconds at USB 1.1 speeds...), the "Full update..." line isn't there.

But no matter, it is quite similar to the CPS SX650g dump - the HID report is byte-for-byte the same. Notably, the "hidrd-convert" tool fails part of the way through parsing it, which is why I suspect that CPS is not following the HID spec. (That's more applicable for the high/low transfer voltages.)

It does seem to be reporting 0% load, though:
