bits, like putting the usb_get_string_simple in instead?<br><br>

This is the megatec protocol. So your device seems indeed to be an<br>
instance of the megatec-over-USB protocol that has been discussed on<br>
the nut-upsuser list in December and January. I believe I mentioned<br>
this last week; here is the excerpt from the relevant email. We are<br>
going in circles, it seems.<br><br>

So my recommendation still stands: try Andrey's patch, and/or try to<br>
get it from Alexander.<br><br>
