USB_CD.sys Indalid Parameter?  Parallel networking?

I have a dead CD rom in a Presario 1270 laptop and I also have a flattened disk drive.  I am attempting to use a USB CD ROM or R/RW drive.  I tried Duse.exe 4.4 and it fired up the USB bus but it would not install the CD device.  It even assigned a drive leter but then it wouldn't install.  I have also tried USB_CD.sys but druing boot up I get an "invalid parameter" error when the config.sys tries to use the device.  What parameters is dos refering to and how do I fix this?  Thank you.

OK since that doesn't appear to have worked and I don't have win 95c on disk... Is there a way to connect to my computer with another through a parallel direct connection and install win 98 or 2000 that way?  I don't have a parallel CD device.

Well post your CONFIG.SYS and AUTOEXEC.BAT files here so we can see what syntax you are using.

The line in config.sys should probably be

device=usb_cd.sys

And presumably you have been here

No, that's not right.

Probably more like

device=usb_cd.sys   /D:MSCD001

thank you. I actually tried it both ways and several other ways.  I even attempted to pare down the config.sys so basically all it had was:

device=usb_cd.sys /D:MSCD001
or
device=usb_cd.sys

I also varied the /D: parameter a few times to see if the naming convention was the problem.  But it always failed the driver installation.  mscdex wasn't really an option after that, even though autoexec does futility attempt it.  But, since there is nothing using MSCD001 or what ever I am attempting to name it... it fails.

Another thing I tried.  I opened my CD enclosure for my USB Panasonic 2X4X4 writer and attached the USB converter to 2 different 16X CD-ROMs one Goldstar and one unknown OEM.  I also attached it to a Yamaha writer I have.  No dice on any of the variations.

Tried that site I linked to my first posting.  And downloaded one of their examples.

It's syntax is the same as we have both posted

device=usb_cd.sys /D:MSCD001

but it's running

device=himem.sys /testmem:off

first before loading usb_cd.sys

If you haven't tried that I suggest you try that.  If you have then I can only suspect that the driver and the CDROM drive are incompatible.

So you were able to then run mscdex and install the drive and assign it a letter?  What were the mscdex parameters you used?

I was able to power up the USB bus and the drive was able to then eject and light up the 'disk in' light ect. it just wouldn't accept the driver.  I have one more drive I can try.

>>> So you were able to then run mscdex and install the drive and assign it a letter?  What were the mscdex parameters you used?

Sorry, misunderstanding here.  The phrase "but it's running" is meant to refer to the line

device=himem.sys /testmem:off

inside config.sys.  This line comes before the

device=usb_cd.sys /D:MSCD001

line in the config.sys.  This is what I meant by "but it's running".

Yes, well device=hi.. ..mem:off has been a part of several of my attmpted variations of boot disks from the begining so I just glossed over that suggestion.  What I was asking was have you ever used the driver(s) and got a cd device to run on the USB bus in Dos mode ane did the drive to work properly and what were the mscdex {?.. ..?} parameters you used to assign a letter to the drive so it could be addressed? The /D:MSCD001, /L:(open drive letter:), /M:?, ect. parameters.  I have been a bit confused by exactly what they should be?

No, I haven't tried it.  I haven't got a USB CDROM drive, I was looking at one for an old 486 laptop and then discovered I could use my parallel port CDROM drive as there were dos drivers for it.

Now it's a TEAC driver, I did a hex dump of the file.  And then a Internet search.

And it's used in IBM laptops.  Here's the page with the instructions for it.

So it is not generic and this may explain why it doesn't work.

Nothing worked.  There appears to be limited resourses for USB/DOS.  I purchased a used CD device and was able to install it that way.  Thank you for your posts.
