I suspect that this is part of the loop in bcmxcp_usb.c around line 154.

How about putting a few upslogx() calls into the read loop mentioned
above (bcmxcp_usb.c, ~line 150). That would confirm that we are
looking in the right place, and also could yield some information such
as the return value of usb_interrupt_read().

If that is causing problems, I have a mostly untested patch here which
might restore some of the logging, but to a separate file so you don't
spam your syslog files.

I will look into what is necessary to reconnect the driver (which I
suspect is how my UPSes eventually start working on OS X).
