Greetings; Belkin is being non-responsive to requests for updated drivers for their line of UPS's, all of which now have a USB port which is the Belkin recommended way to talk to these things.
Unforch, the belkin supplied *nix stuff was last compiled on an rh5.2 machine using gcc-2.7.2, so there has been some bitrot. I believe the problem to be that when their version of upsd is trying to open the /dev/name its given, it is assuming and hard coded to do the ioctl's to set the ports speed in baudrate, width of word, parity etc. Getting failure messages for that, it retrys the open until it has 1024 links to /dev/hiddev0 according to an lsof|grep hiddev0, all of which presumably have failed so it never actually opens the /dev/hiddev0 port in r/w mode successfully. I can, from a shell, 'cat' the data from this port, its not very fast taking about 8-10 seconds to output all the integers or bytes to constitute a complete screen update when translated by the gui into sensible data. My proposal, and I'll see if I can make a patch, is to add to the hiddev.c code, stubs for these otherwise useless functions that do nothing but return a 0 indicating success so that these legacy drivers can make use of a port whose data is just fine but fails these configuration things that don't mean squat to hiddev anyway. Would this effort at making legacy drivers who think they are using /dev/ttySx, work with /dev/hiddev constitute an acceptable reason for such a patch to hiddev.c? -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
