Personally I favor Vantec over Sabrent.
Both read as USB hubs that will register in DM. Plan to use on an old
Serial-only APC BP1100 UPS. Wish to use as back-up, and, test to figure
out whether a newer APC UPS is being "USB-comm-silly." Another working
project!
Plan to order one of the above with 15ft Non-Active USB extension cable.
Opinions welcome!
Best, Duncan
