Translated they are both referred to by the same word (jakaja), but I do also see people on the net using both terms for same things.
Problem being that I don't know who makes good usb stuff. If it was a mouse or a game controller I'd go for Microsoft or Logitech.
Gotcha. Seeing your from Finland, that adds more context. Translation nuances.
This won't solve yer problem, but is hopefully educational or slightly interesting:
Technically, I'd reserve usage of the term splitter for really primitive electrical branches. So an adapter to get 3 power outlets from one is a splitter. A T coupler for co-axial cable is a splitter. In both cases, it's just copper lines running from the source jack to the output jacks.
A hub implies a bit more wiring (and cross-wiring so the input lines lead to somebody's output lines, etc).
That's probably the key point right there. In a co-ax splitter, the center copper line is solid through all 3 ends. The outer shell line is the same.
In a hub, there are multiple lines per jack, and some of those lines are power, some are incoming, some are outgoing signal lines. The outgoing signal line from port 1 has to lead to the incoming signal line on port 2. Otherwise it'd be like expecting to listen to the moutpiece on a telephone.
Technically, a telephone splitter qualifies under this pattern of being defined a hub, so there might be more human whim on what differentiates a device for either term.
