Based on what do you say that? The ones that I'm aware of -- by
USRobotics, Multitech and Zoom -- have explicit Linux support. Generally
speaking, USB modems are _less_ likely to be winmodems than internal
cards or motherboard built-ins; indeed any modems that meet the USB
Communication Device Class Abstract Control Model (CDC ACM) standard
will work using the Linux "acm" driver.

Some off-brand USB modems are not CDC-ACM compliant and as such won't
work with Linux (many of them won't work with Vista either); but this is
a far cry from writing off the category. Compliant modems are certainly
easy enough to find.
