Hi, I just bought a cheap UPS and apparently I'm hitting the same issue
that's described here:
http://comments.gmane.org/gmane.comp.monitoring.nut.user/6146

Mine is a different brand: "Kanji" which appears to be the argentinian
dealler for some generic chinese manufacturer. My model is also 800VA
and identified in the same way, so maybe is the same UPS under a
different brand:

[ 1244.817586] usb 4-2: new low-speed USB device number 5 using xhci_hcd
[ 1244.839172] usb 4-2: New USB device found, idVendor=0001, idProduct=0000
[ 1244.839183] usb 4-2: New USB device strings: Mfr=1, Product=1,
SerialNumber=1
[ 1244.839191] usb 4-2: Product: ATCL FOR UPS
[ 1244.839196] usb 4-2: Manufacturer: ATCL FOR UPS
[ 1244.839201] usb 4-2: SerialNumber: ATCL FOR UPS


I understand that because of the bogus product id and vendor id and the
very scarce info NUT cannot properly support this UPS. However, in hope
that maybe it's a known protocol or it's helpfull anyway, I made usb
captures of the windows software that comes with the ups for windows. I
did two captures: one with the proc interface to usbmon and one with
with wireshark.
I have no experience writing drivers, but I can try experimental drivers
to help.

Kind regards.
