Unhappy External USB devices in DOS

I am trying to get an external CDROM drive to work in DOS using USBCD.SYS and USBASPI. It searches for USB drives, finds the Phillips CDROM, says that the device driver is installed, then goes back to the "C" prompt and does'nt assign it a drive letter. can anyone help please?.

Laptop CDROM drive is faulty. I have formatted the hard drive and need to re-install XP. I have purchased an external Phillips DVD-RW Drive which I want to use to install the software. I have got the laptop to recognise it, but that is as far as I can get.

so it can't boot from a cd in the usb drive? i would try booting from the xp cd and failing that (keep in mind this is my solution which may not suit you) use a live cd linux to copy the xp cd onto the hdd.

yes, I can't get it to boot from the USB drive. I recognises that it is a Phillips DVD-RW Drive and says that the "Device Driver is Installed" but does not assign it a drive letter.

have you tried enabling "boot from usb device"? also some computers have a boot menu you can bring up by striking a certain key, allowing you to select from all bootable devices.

Cannot find that in the BIOS. and tried various keys as well. If this is any help I have already added these lines to my "Config.sys"

device=usbaspi.sys
device=usbcd.sys /D:mscd001

This finds the usb DVD-RW and says that the device driver is installed as mentioned before. I think I need to add a command line to my "Autoexec.bat" . Is that right? Thanks for the help
