Well, a quick look at the Quick-Install PDF says it is a:
"Soft56K Data Fax Voice CARP"
In part 3. of the DX-M300 Manual.
Plus, I just D/L'd the Drivers, it is a conexant chipset modem, highly
suspicious it won't work. So my gut answer is no. Anyone is free to
prove me wrong.
If you want a USB POTS Modem, get a USB Serial Port dongle, then get a
Fully Serial Modem. It is very tough to make an External modem with a
(real) Serial port a "Winmodem" and still be capable of v.92.

By "Fully Serial Modem" you mean a modem that connects ONLY through a serial port?
Thanks a lot for your help.

Yes. Only with a truly serial external modem, can you be assured a
non-Winmodem (Winmodem being controllerless).
Though the Dynex product page says:
Winmodem (Controllerless) No
I have very little faith in it, I have seen quite a few modems claim to
not be controllerless... only to find that they classify the Main
processor (The Pentium/Athlon... etc processor) to be the controller. So
it is marketing that lies.

The gold standard by which other lesser modems are compared is the USR
(or for a while 3Com) Courier V.Everything external serial.
I picked one up on eBay with a warranty and power cube for $49 USD.
You can get them with various warranties for less on eBay but since
shipping is shipping... (also the one I bought was in Canada as am I so
I didn't have to worry about customs brokerage fees). Manuals are
available on the USR web site (just google for Courier "Command
Reference" )
New, they go here for $350.
Lesser external modems may also work depending on the quality and smarts
you want. It has to have on-board smarts and not mention anything about
'winmodem'. Note: the courier docs also talk about installing drivers
but they are not true drivers but an install wizzard thingy that windows
needs that linux doesn't.
Your best bet when getting any hardware is to get, in writing if need
be, assurance that if it doesn't work with your linux you can return it
for a full __refund__, not just a store credit.
Good luck.
Doug.

On Oct. 18 my ISP, att.net.mx, would no longer connect thru my
USRobotics 56K External Serial modem.
Discussions with technicians, who insisted on only talking from a M$ OS,
solved nothing.
My hunch, based on a new "sound" in the dialup process was that they
added V.92 protocol which the modem would not recognize.
So I bought this:
http://www.newegg.com/Product/Product.asp?Item=N82E16825137104
for $24, 1/4 of the price of the old one that I bought here in Mexico 4
years ago.
Solved the problem. I based the decision on a review that said the OP is
using it on Linux.
Before the new modem arrived I used Telmex as ISP. Their service is the
*pits*, lots of SIGHUP's, very slooooow. And guess what? You cannot
cancel your subscription. Cancellations not allowed. There is a reason
that the owner is the richest man in Mexico.

The V.92 negotiation tones take some time. If it takes too long before
the other modem tries V.90, then your modem will give up. There's an S
register where you can extend this timeout. You can also get a V.92
update for the USR if its a Courier. Remember, USR also makes the
Sportster external serial which is a whole 'nother kettle of brine and
nothing like a Courier.
I'm glad your cheap modem worked but if you (still) have the Courier, you
could try fiddling with it. It will have better noisy-line fault
tolerance.

hardware modems worked
FWIW the best modems I have ever used were the USR/3Com V,Everything Courier and the original 3C567ish PC-Card. The PC Card had a 10BASET NIC and a V.90 modem in it. Both used external dongles for the line connector, not that stupid XJack thing, so the card fit in one slot without making the other slot useless. It used Motorola's "data pump" and the phone dongle was an expensive full size industrial grade Data Access Arrangement. The signal quality was great because of using full size magnetic parts instead of those el cheapo transistor radio transformers used in most PC Card modems. I was on a 7-mile long subscriber loop and those two modems could negotiate a 40 Kbps link every time. No other modem I had could do more than 28.8 on that line. The card was stolen or I'd still be using it.
Unfortunately, that division of 3Com was taken over by bean counters. one of whom invented the term "Winmodem." 3Com discontinued its hardware modems after that except for the one Lucent Venus PCI card.
