Try disabling real-mode USB support in the BIOS.

I'm happy jumper's idea solved it! And I'm happy you tried the experiment I proposed: because eventually coming up is different from never coming up, and knowing for sure which case one has helps a lot in finding solutions, but also because, when it comes up -- albeit after a long time --, many further experiments may be performed in order to find out what's happening... of course, this time that avenue won't have to be pursued any further, because you've already hit jackpot! Congratulations! And thanks for reporting back: the most frustrating experience for the helpers is to be left without notice of how it all ended. You rock!

Windows 98 does not match USB partitions found by DOS with those found by Windows. This leads to two Drive Letters referencing the same Partition. This can lead to corruption if both are written to. In addition the DOS based Drive Letter is not recognized as an USB drive so it cannot be safely removed. Since they both have the same signature, some internal data is shared causing crashes to occur if the Windows based Drive Letter is removed.
First, I'm sorry to be so slow responding to dencorso's suggestion to let win98 run overnight to see if it does eventually come up when I have a USB flash drive installed. It DOES do so -- it actually takes about 45 min. to an hour. Normal would be under a minute -- this is a 2.4 GHz machine, I believe. HOWEVER, if I look at Win Explorer, the flash drive is there twice: Once at D and once at E. Clicking to 'Safely Remove Hardware' only gets rid of one of these. If I bring up Win 98 without the flash drive inserted then D is the CD drive (as you'd expect) and E is the flash drive. 'Safely Remove Hardware' works as it should.Either way, when I look at Device Manager I have a 'USB Mass Storage' and under a new heading of 'Storage Device' I have 'Disk Drive.'Very strange ...
To avoid these problems you must insure that only one OS recognizes the partitions. To prevent this you can do one or more of the following:
1. Disable BIOS USB Mass Storage support.
2. Remove or disable the USB Drive during BIOS booting.
3. Remove or disable the USB Mass Storage Drivers in Windows 98.
4. Use Windows Only Partitions with my Patches.

I understand that, after disabling USB emulation in the BIOS, just one letter is assigned to each drive, albeit the order changes depending on whether the pendrive is inserted in one of the USB connectors or not. So, IMO, nothing further needs to be done, at the moment... am I mistaken?

I have now followed jumper's suggestion to disable USB emulation in the bios. That solves the problem: It now comes up in a perfectly normal amount of time even with a flash drive installed. If the flash drive is in place then it comes up with that drive at D and the CD at E -- the reverse of what happens if the flash drive is installed after booting. Again, many thanks!
Maybe useful, maybe not, something now lost in the midst of time, Letter Assigner:

I did not know about Letter Assigner; I found and downloaded a copy by following the Wayback link. Don't need it now, but I long ago gave up trying to decide what software I would never ever need. That's why I have NUSB, actually, and from fairly early days -- 3.0 at least. That one is on my 98SE2ME laptop and I think I have 2.x saved somewhere.
On to the NEXT problem on this DELL 2400/Win 98SE machine. Since this machine was never supported by Dell for Win 98 this has been interesting and I may write it up as member project if no one else has done so.
(Now that 98SE is fully working the next step on that machine is getting a truly awful -- but interesting -- game card to play, 'just because.' This is a Riptide 90079-2 -- sound, joystick, MIDI, and modem in one PCI slot, apparently only OEM in a bunch of Win 98 HP machines. I have all the drivers but my first attempt was killed by an excess of IRQ conflicts and I have a lot to learn about solving those. One thing I learned from this thread was the use of Safe Mode to get complete reporting from Device Manager.)
I very much appreciate the educational material, especially rloew's tutorial which clarified much. I was aware that having two views of the same device could be fatal so I did nothing to cause a write to that device.
I am curious about exactly what was going on during the near-hour long process of Windows coming up (when the BIOS USB support was enabled). If I understand correctly, DOS takes the BIOS info but Windows still discovers the device on its own and with no coordination, you get two routes to the same one. But -- why did this take so long? For some reason this brings to mind:
"But they argued all night,
o'er which had the right
to do what with which,
and to whom."
As I see things I now have ONLY the Windows view, which on this machine is plenty quick.

I suspect it was reading the whole FAT table using slow USB 1.1 protocol. Or something like that. When my Windows 98 computer with USB 1.1 worked, it always froze when I accessed USB drive the first time after boot, and USB drive light blinked meaning that the read operation was performed. The time of the freezing depended on the size of the drive. 4 GB usb flash stick froze my computer for less than a minute, 16 Gb flash stick froze it for about 3.5 minutes, and 320 GB USB HDD - for about 10 minutes or more. I didn't overcome this problem. What is the size of your drive?
