Hello,
Hello Ricardo,
I'm using NUT to manage a MGE Ellipse ASR UPS, with the newhidups
Same here except that i'm doing it through the serial link.
driver.
It works fine, except that after a few hours, I get a few errors from
the kernel and the driver dies.
I have some lost connections which usually last for about 3 seconds.
Here's the output from the syslog:
Apr 26 02:00:41 ezquiel kernel: usb 1-1: usbfs: USBDEVFS_CONTROL failed
cmd newhidups rqt 128 rq 6 len 255 ret -110

- Driver not connected
I'm using a 2.6.16 kernel and NUT 2.0.3 (both are stock debian builds).
Anyone has any ideas about the problem?
Ok, so here is my guess:
"IF" you happen to have a too short power supply on that computer this
can cause the problem. I have a rather too small P.S. on my system: it
works correctly most of the time but gives me some quirks from time to
time. The serial link is that little bit too much for it, maybe the USB
is the same for you. If you can test that with another P.S. more
powerfull...
The fact that your driver dies and not mine is probably due to the
differences between USB and serial... Maybe.
