<p class=MsoNormal>Hi all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve been trying to get a TrippLite 700DV communicating
with nut in Solaris. The problem was that I would successfully send a message
to the ups, but wouldn’t be able to receive anything. After some snooping
around I found this bit of code in libusb.c libusb_get_interrupt(). <o:p></o:p></p>

<p class=MsoNormal>It seems that when using Sun libusb, nut completely blocks
out the read attempt. I removed the preprocessor directives and voila. Worked
perfectly. There must have been a reason for this at some point, but I can’t
find any comments on the issue. And it seems to be unnecessarily blocking out usb
communication when using Sun libusb. Does anyone know the reason for this? Should
I work around the issue in the tripplite_usb driver, or can it be fixed directly
in libusb.c? Maybe other UPS drivers on SUN haven’t been working for this
reason…<o:p></o:p></p>
