With my existing 2.6.22.2-42.fc6 kernel, reloading the hci_usb with isoc=0 does help somewhat. I can plug in more than 16 dongles and the system remains stable. The mouse and keyboard remain usable. However, the 17th USB device is not recognized. I am reluctant to try the 2.6.23-rc3 kernel you suggest, since my development shop is all standardized on the current FC release. I don't want my machine to get out of sync with the rest of my team. I think that I'll just tell my customer that he'll have to wait on more than 16. After all, if the application can't accomplish what it wants with 16 blueteeth, why do they need more ? So, thanks for your help. I'm not going to waste any more time on this.

If not, then that is an USB subsystem issue. Make sure you use 2.6.23-rc3.
