If there are any driver options, they'd likely be only for
the newer Intel-based iMacs; the non-PPC Macs.
The older iMac G4, depending on the model, could
support the USB standard relative to their vintage;
the oldest being the USB 1 slowest. The last G4
iMac had USB 2.0 standard, plus 1.1 on keyboard.
Not sure how any other USB adapter allowing
use of other ports and their speeds could work.
Probably not at all. I haven't checked into such.
The Ethernet to USB or FireWire to USB may
be even farther away from possibilities with the
product you are considering.
If you know of someone with a newer Intel-based
Mac, there may be some support for using it there.
In fact, finding reference to any support should be
possible from the product manufacturer if any new
drivers or any support for Intel Mac is available.
There may be user groups or some other discussion
on the matter online under cover of a chat forum, etc.
The early iMac G4 with LCD panel and chrome arm
does not have built-in wireless 802.11/n support, and
from what I can tell (in quick search) that is needed.
Among other things. Note the topics in search below.
NetGear RangeMax USB Adapter driver Mac OS X:

If the product is new, the odds are highest it would be
probably able to work with the newest Macs only...
That's my speculation, and since the iMac G4 is old
technology, a new dual USB support may be marginal
if supportable at all outside of the recent Intel-Macs.
There may be third party open source drivers for these.
In any event...
Good luck & happy computing! 🙂
