I want to build an small data logger based around ATMEL's 8535 (or one of
the AVR Mega).
I need to log around 300MBytes of data. USB memory sticks are cost effective
storage mediums. Is there a simple way to interface a USB memory stick with
an ATMEL microcotroller?

No. Use a CompactFlash card.

Use a SD/MMC card ,much easier than compactflash

Just set the AVR for SPI , and connect the SD/MMC via a cpl of
voltagedividers.

See www.microsyl.com (LCD sign)

This chip will do it - does all the FAT stuff from a simple serial interface., as well as allowing
access to USB mice, keyboards, printers etc.

"USBWiz".. it's a preprogrammed LPC2114 ARM chip used with an ISP1160?

There's something a bit sad about using a double-digit MHz 128K 32-bit
processor to interface an 8-bit micro with a USB flash drive, but I
bet that could be pretty useful in some circumstances.

And for 40 pounds (60 USD), you can almost get a complete 32bit board
with USB and many other stuffs.

At 40 British pounds not exactly cheap.

The advantage of the USB memory stick is that many people have one and
they are easy to connect to just about any PC.
The SD/MMC is easier to connect to the AVR but will require a memory reader
on most PCs.

Check www.avrfreaks.net.
There is someone which has a ready application for SD connection
and sells the source code etc. for about $130
I think they use a mega128.

A part with external bus might be good if you want to use Compactflash.

Although the readers are so cheap that it may be viable to ship one with the product.

Have a look at this one for the AVR (It's free)

Maybe use BabelFish
