The FT8U232AM has two types of driver, one is a VCP (virtual comm port) and
the other is accessed through a dll.  The specific user information, such as
the device name, is held on the eeprom.  I have never used them without the
eeprom, but it does say it's optional.  It might be worth a call to support
for this, but before you do....

Try these:
1. You can't install both sets of drivers on one machine, so check for this
first.
2. Have you read the application note AN232-03?  This is a step by step
installation for the drivers under W98.  It does ask that the install is on
a fresh machine though, so you will have to read appendix A for the
uninstall docs.  I couldn't find the app note on their site, but you can
download it at http://www.dlpdesign.com/usb-prev/images/AN232-03.PDF
3. It could be a problem with W98.  Try deleting the unknown device in the
HW device manager.
4. Either give FTDI a call (they are quite busy) or your local distributor.
Here in the UK it's Alpha Micro Systems in the UK and they give good support
too.

Hope this helps,

Brian.
