Thanks for the feedback guys... but I'm confused what I'm supposed to
do... Is there anyway to talk to the driver maintainer about this
issue??

Hi,
To find the problem, check the list for my thread DP55KG, you should
run a debug kernel and grab the usbmon output and report it to the
list.
Also stop nut and run each service manually with -DDDDDDDDD to see
what is happening within nut, but if it is not really obvious, the
kernel/nut developers will need to see the usbmon output.

Hi Justin,
I'm using a MSI KM400 motherboard with a dual core AMD, running
Ubuntu 2.6.28-11.42-server in 64 bit mode.
I noticed on dmesg the following error - not too sure if this helps:
"usb 2-2: usbfs: process 24736 (tripplite_usb) did not claim
interface 0 before use"
One other thing - this UPS has just been provided as a replacement
from tripplite (i.e. its a new model), as I had a pretty identical
one before - which worked perfectly with NUT, but used the USBHID-
UPS driver. Why this one is so different - I have no idea!!
Regards

Hi,
I'm running the latest version of NUT and with the above UPS and
I keep getting the following error:
"tripplite_usb[3308]: Error reading B value: Device detached?
(error 0: could not claim interface 0: Device or resource busy)"
The device keeps disconnecting and re-connecting until fails.
I've tried to see if others are getting this - but I could not
locate a cause/resolution for this. I provide below the messages
from the driver in debug:

Hi,
What motherboard/chipset are you using?
Justin.
