Is it possible to find a driver for MEmorex USB 2.0 flash drive to use on my Win98?

Memorex offeres drivers for many of their models on their website... but if not, send their tech support an email. They are more helpful than most.
However,
most companies are not providing drivers for Flash for W98 or WME because they are no longer supported by Microsoft and Microsoft has put out a great deal of pressure to get all companies on board.
