Unorthodox UPS USB Connectivity

[ytene]

Hello Everyone...

I have a bit of an odd question concerning the connectivity between a QNAP NAS and a UPS (Specifically, an APC Smart-UPS C 1500VA):-

The odd question is this... I have a couple of QNAP NAS boxes both connected to this UPS. Unfortunately, the UPS itself only has a single USB socket, but I am using it to protect both a TVS-672XT and an older TS-670. With the singular USB socket on the UPS, I know I can connect it directly to either NAS and both see it instantly and it works perfectly to control their performance during power loss.

I am wondering if it would be possible for me to run from the UPS to a USB splitter cable, or a simple hub, and then from the hub to both QNAP NAS boxes? In theory, ho ho, I think this should work. USB is a bus, so it is designed to connect multiple devices at the same time. Unfortunately I know from experience that not all manufacturers fully support a shared bus... So before I spend money on a hub and cables, I thought it would be a good idea to ask the community if anyone has experience of this sort of configuration and if so, what they would recommend.

Thanks in advance for any responses.

not an uncommon thing at all .. don't tinker with USB splitters .. connect the UPS to one box make that the network master and the other network slave, check the manual for more info
