>Description:
Cyber Power AE550 UPS is plugged in to the machine via USB. Kernel
attaches to it as a HID, which prevents UPS software (NUT, Network UPS Tools
2.0.4 in ports collection) from attaching to it. Similar changes have been
patched into the kernel for MGE UPSes.
As far as I can tell there is no way to overcome this problem with
configuration or with code changes within NUT.
>How-To-Repeat:
Hook Cyber Power AE550 UPS up to machine via USB, and then try to
communicate with it with NUT in ports collection. The latest release of NUT,
2.2.0, also does not work.
>Fix:
A change in the kernel so that it won't attach to the UPS as a HID is
needed. I have attached patches with Vendor/Product info to accomplish this.
The change has been tested and works correctly.
