[Nut-upsuser] TrippLite 1500XL problems, continued.

[Junk Mail]

So a month or more ago, I posted about continual disconnect messages from 
this UPS (roughly 2/hour), using nut 2.2.0 on debian etch. Now, I've 
finally gotten around to running tripplite_usb in debug mode, and these 
are the results:

...
send_cmd(msg_len=2, type='L')
send_cmd(msg_len=2, type='S')
send_cmd(msg_len=2, type='B')
send_cmd(msg_len=2, type='L')
send_cmd(msg_len=2, type='S')
send_cmd(msg_len=2, type='B')
send_cmd: send_try = 3, recv_try = 10

Error reading B value: Device detached? (error 0: error sending control 
message: Operation not permitted)

Any help would rock.
