[Nut-upsuser] Tripplite INTERNETX525

[Farrukh Ahmad]

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:

Really would appreciate some help on this...
