I have a Gericom/Samsung DVD external USB burner (TSST Corp TS-H552U), which I'm trying to run on my laptop (Windows 98SE). (The burner is supposed to run with 98SE.) The burner seems to have installed correctly in that - as per the instructions - the DVD writer appears under CDROM in Device Manager and Hi-speed USB-IDE Bridge Controller shows up under both Universal Serial Bus Controller and under Hard Disk Controller. However, the DVD drive will not show up in either Nero or HT Fireman (a free DVD burning programme). I also downloaded something called SFDNWIN from the Samsung site that assists in updating their firmware and that also soes not see the burner (it sees the laptop's own DVD-Rom only). I updated Nero on their advice but it did not help and it now seems clear that the problem is not with the burning software, but elsewhere. I don't understand why Windows Device Manager clearly sees the DVD burner but burner software won't. I'd be very grateful for any advice.
