Note that I still have trouble starting mge-shut - 50+% of the time it<br>
says "Unable to get Report Descriptor"<br>

Have you also tried the newmge-ups driver? Being based on the same core as the usbhid-ups (USB) driver, it may be a little more forgiving in case of timeouts (although I'm not very familiar with it's predecessor, mge-shut).<br>
</blockquote><div><br>CAUTION: newmge-shut has still a major issue I haven't yet solved (which explains why it has not yet superseded): a loss of synchronization tends to happen.<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
The SHUT protocol is *very* verbose and uses a slow 2400 baud link, so you want to give it lots of time before giving up (reading a 1500+ bytes report descriptor will take more than 10 seconds). You may want to increase MAXAGE in upsd.conf to at least double that, to prevent PINGing the driver to death.<br>
</blockquote></div><br>I still have a point in my TODO list which is the baudrate negotiation. newer units supports it.<br>there are also rooms for improvement on the startup sequence.<br clear="all"><br>Daniel: I'm interested in debug trace of these startup failure. just to see how it fails, and what should be done.<br>
