They're pretty standard so they all should.  If your
distribution doesn't detect and mount one automatically,
see this article from the December Linux Journal:

AFAIK they all do.  Just build your kernel with USB Mass Storage
support.

Actually, you'll need a few more things besides that.

  1. SCSI Disk Support.

  2. The VFAT file system. (This isn't *strictly* needed, as you could
     probably build the Linux filesystem of your choice on the flash
     drive, but most of them come preformatted in VFAT, and neither a
     Mac nor a Windows PC is going to know what to make of, say, an
     ext3 filesystem. Also, pretty much all digital cameras, MP3
     players, and PDAs expect their flash storage to be VFAT-
     formatted.)

  3. Native Language Support (NLS) for Codepage 437 and possibly ISO
     8859-1. (I found that without this, Linux could read the contents
     of the drive, but would not write to it.)

Having the USB Device Filesystem and Hotplug support enabled certainly
doesn't hurt, either, although I haven't turned them off just to see
how difficult the process is without them. The list above may not be
exhaustive.

I've successfully used a PQI Intelligent Stick, a Lexar JumpDrive
Trio, and a PPA 6-in-1 Card Reader with Linux. (Gentoo 1.4, running
version 2.4.20-r9 of the gentoo-sources kernel, to be specific.)

	Yes they do. There is Flash software on Red Hat 9 that correctly 
identified my USB scanner and a USB transiever to a router.

True, USB Mass Storage won't work without it.  USM-MS is essentially
SCSI over USB.

Aye, I'd assumed that.

I don't have that built in and to date have not had problems.  Of course
YMMV as I've a tiny sample size.
