Forget using USB for storage. There are huge numbers of NAS (network
attached storage) boxes that use ethernet. You can plug that directly
into any wireless router, and it will work. No need for a dedicated
device.
However, before you buy a wireless file storage box, you might play
with the performance numbers.

(Thruput is measured in MBytes per sec)
802.11g at 54Mbits/sec will give you about 25Mbits/sec TCP thruput
maximum. That's about 3MBytes/sec thruput. With the usual overhead,
you'll be lucky to get 2.5MBytes/sec thruput.
If you dumped the wireless, and just connected with 100baseTX ethernet
between the computahs and the NAS storage, you'll be getting about
90Mbits/sec raw rate, or about 10MBytes/sec with overhead. If you get
a gigabit ethernet interface, it will be MUCH faster at perhaps
100MBytes/sec (if your computers can handle it).
Now, there's nothing wrong with 3MBytes/sec read/write speed, but you
might be disappointed if you're expecting wire speed performance. See
the read/write performance figures on the chart for a clue. Be sure
to read the NAS tutorials, how-to's, etc on the URL above.
Also, you might wanna run your own benchmarks. See IPerf at:

Ask if you need help getting results with IPerf.
