Will wireless USB hub lower the quality of my USB sound card output?
 
Will wireless USB hub lower the quality of my USB sound card output?

This is the USB hub i had my eye on:
NEW Belkin High Speed Wireless USB Hub F5U301 - eBay (item 390276127670 end time Jan-05-11 19:08:36 PST)

and this is my sound card:
AUDIOTRAK Prodigy CUBE External USB Sound Card - eBay (item 110624971376 end time Jan-13-11 17:07:11 PST)

I figured, since the signal is transmitted by wireless before it gets
processed in the sound card, then i will not lower the quality.

That's when you guys come in...

Those wireless USB hubs don't pass USB audio. So, it won't work at all.

Too bad... I was interested in that too.

How can a wireless hub know whether that data it is being passed is audio or otherwise?

Because different kinds of data use different kinds of USB protocols. A printer will use bulk mode, a USB audio device isochronous adaptative. One can only guess that the chip inside don't support all the USB protocols.

If you look at the reviews of those devices on Amazon or on the web, you'll see that people cannot get them to work with USB soundcards or speakers. See for example: http://www.amazon.com/Belkin-Wireles.../dp/B000WM5HUO

And Belkin's competitors (Iogear) do actually state that their hub doesn't support USB audio speakers ( IOGEAR - GUWH104KIT - Wireless USB Hub and Adapter )

OK thanks for the explanation.

From page 19 of the Belkin F5U301 user manual (link below).....

Quote:

Support for USB Classes

Audio devices (“USB Audio” class) and some webcams (“USB Video” class), which have isochronous end points, are not supported by the Hub.
