OK, I took a bit of time to do some testing. I backed up my C: drive,
tested
the WDC software, then restored C: so there is no junk left over.
First, I don't really find the entries in Device Manager to be that
helpful.
I used a copy of Everest (storage entries), to try to get more info about
the controller on my USB to IDE enclosure. You can get a copy of the free
version of Everest here. Lavalys is still selling this program, and the
modern version has a lot more stuff in it, than this version does. But
this version is free.

In Device Manager, I have one entry
USB Mass Storage Device
driver = usbstor.sys
In Everest, I see an entry in the storage section, for
Cypress AT2LP RC42 (that is a USB to IDE chip)
VID=04b4 PID=6830 Rev=0420
You can gets VID and PID values for USB devices here.
This allows you to double check the info. This list is
informally maintained, and there is no guarantee that
all USB devices ever made, are listed here. The official
list is kept private.

6830 CY7C68300A EZ-USB AT2 USB 2.0 to ATA/ATAPI
Now, under the "Disk Drives" section of my Device Manager, I have
this, and I suspect this is critical to my success.
WDC AC24 300L USB Device
The hard drive is actually a AC24300 4.3GB IDE hard drive from 1999.
It's the only WDC drive I own.
That is my hardware summary. The important part seems to be, my
USB to IDE controller is able to make a "Disk Drives" entry with
the word "WDC" in it appear. I don't know if your situation is
different or not.

Now the software tests.
The Acronis for my drive, is the file "tih_s_e.exe" size 126,924,016
bytes.

First, I tried to install it, with the USB-IDE enclosure turned off.
The installer refused, saying I had no Western Digital drive.
I switched on the drive, and this time, the Acronis installer
agreed to install the software. I didn't actually test the software,
because I believe you were getting stuck at the installation stage,
and that was enough testing for me. After a reboot, I was able to
start the Acronis program without a problem. But there didn't appear
to be anything worth testing in there, so I quit the program. At
least the program opened OK.
Next, I tested the DataLifeGuard software for Windows.

That worked fine, and could see the USB based WDC drive. I
did a Quick Test (which scanned the entire drive in fact) and
my drive passed. It's only a 4.3GB drive, so no big deal.
Next, I tried the DataLifeGuard MSDOS version. Now, it isn't likely
that DOS would have a USB driver, and the WDC floppy didn't let me down.
http://support.wdc.com/download/dlg/DlgDiagv504f.zip
The floppy installed OK. I booted with the floppy, but the
executable on the floppy could not see a WDC drive.
Next, I booted the computer with my all-powerful Win98 prepared
MSDOS floppy. That floppy could actually read the 4GB FAT32 partition
on the USB based drive. So, seeing as I could see the files on the
drive, I tried running the executable on the other floppy (the floppy
built purely via the WDC download). The executable could be run from
the A:\ prompt no problem, but it still refused to see the drive.
It could be, the software was looking for I/O space IDE
interfaces, which were common on older motherboards. So the
test result was not particularly surprising. The software
appears to be produced by Knoll Ontrack, and WDC didn't write it.
So those are my results. The most important result, is my USB to
IDE enclosure with Cypress chip, was able to convince the Acronis
installer to work.
Try Everest, and see if the name of your drive is revealed or not.
You may also be able to determine the controller chip name and part
number.
HTH,
