[Nut-upsuser] USB UPS problem

[Eyal Lebedinsky]

Maybe a kernel USB issue, but people on this list may have encountered this issue.

I am testing a new UPS (EATON 5E 1500iUSB) and am having a problem with the USB connection failing.
My old UPS (EATON Ellipse MAX 1500) works just fine with the latest f30. Both devices identify as
	ID 0463:ffff MGE UPS Systems UPS

To narrow the focus I booted recent live CDs on a PC that has no other USB devices attached
beyond the keyboard and mouse.

Looks good.

The above repeats indefinitely. Same with the latest f30. Replacing the USB cable does not improve this.

Maybe a USB module had a parameter change and I need to override it? Longer timeout? More retries?

TIA
