At present, I only have one Bluetooth device (USB adaptor) , by connectBlue, and that has an internal Bluetooth stack, so the only driver it needs is the FTDI USB-Serial driver. However, I have recently ordered some cheaper devices on eBay, which I assume will not have an inbuilt stack, so then I'll be needing to try some W98 stacks.I may have found something useful, by searching WIDCOMM drivers, prompted by your suggestion. Here are some potential candidates to test. The XP WIDCOMM Bluetooth Stack can be made to accept almost any Bluetooth Radio by editing the .inf, in the same way as we do with NUSB on 9x/ME, so perhaps one or more of those 98 WIDCOMM drivers can be turned into a general solution...
There are some Bluetooth devices that support Windows 98. They may have useable Drivers.
The Widcomm stack (linked above) does look fairly generic, and I have found another (slightly newer) one here : http://web.archive.o.../USB-BU2050.zip
PS. Two more (one even newer) Widcomm exemplars :
I think these are the pages where you can download the above packages :
There definitely is a Bluetooth driver that works in 9x. I had one driver package from a BT dongle installation mini-CD, then I found (maybe mentioned here in these forums?) two other rather huge packages (35MB and 62MB, respectively) that were distributed by D-Link and Emtec. All of these packages contain an inf with a long list of vendor and product IDs and software produced by Widcomm.
