I recall using these drivers several years ago. As I recall, the problem is that they're not amenable to hot-swapping. That is, is you're using a USB flash drive with them, there was no code that allowed you to remove the drive and substitute another without rebooting.
Has this situation changed? On a related note, I have several Ralink RT5370 USB Wifi dongles that I find to be quite useful. Has anyone gotten one to work with Windows 98SE (I won't even bring up MS-DOS)? I wondered if I could find a Windows 2000 miniport driver for it, that it might work in Windows 98. --Chuck
