WinPower 5.6.0.5 detects only 1 Eaton 9145 UPS at a time

Hi Folks,

I have a DELL T430 server connected to 2 Eaton 9145 UPSes through the supplied USB cables for UPS monitoring. The UPS management software winpower detects only 1 of these UPS at a time. If I disconnect UPS2 then UPS1 is detected. If I disconnect UPS1 then UPS2 is detected. When both the UPS cables are connected only 1 UPS is detected.

Any idea how to solve this? Both UPS are identical and otherwise working fine. Just the software detects only 1 UPS at a time. Running latest winpower 5.6.0.5.

Thanks!
