SignalGround.com has the review: "So as not to prolong the inevitable, we'll say it now: the Zoom 56K USB worked with
the Linux ACM driver and a pppd/chat-based dialer script, just like the D-Link
modem did. Under Mandrake 7.2, setup for the Zoom modem was exactly the same
for both modems. Unfortunately, we also had the same problems using KPPP (from
KDE 2.01) as we did with the D-Link modem."
