[Nut-upsuser] [POSSIBLE FRAUD] Re: [EXTERNAL] Re: Help with Tripp Lite Internet600U

[Larry Fahnoe]

The loss of communication to USB devices has been discussed before on this
list. I do not recall the particulars (& thus do not know if they're
relevant to the situation at hand), but it seems to me that it was
ultimately related to the USB libraries being used. Charles Lepple was
instrumental in the thread I'm thinking of. Roger's suggestion of a more
intelligent cron job sounds very beneficial for a short term work-around,
but if it were my system I'd rather get the tools working properly which
may involve research into the code and how it is built on the given
platform. Sorry I don't have a more specific suggestion to offer!
