Problems with optical disks and with USB 2.0

[CantDo]

I'm working on a computer running Windows XP Pro SP2. The system has a Pentium 4 1.5GHz processor, 512MB 133Mhz SD RAM. I've installed a USB 2.0 PCI card, a Sony CD/RW-DVD-Rom Drive and a Samsung DVD +/- R/RW drive. The computer sees all of these devices OK (in harward profiles).

The problems are:

1) Although the system sees the drives, I cannot (initially) see anything on the drives when I use Windows Explorer (i.e., My Computer) to navigate to them. Nor will an autoexec CD launch when inserted. This is true whether I put in a CD-Rom, CD-R or Music CD. However, if I re-boot the computer with the disk in the drive, I can magically see everything after the re-boot. But, mysteriously, Media Player (for one) will play a music CD even before a re-boot! I suspect there is some form of corruption in the OS, but I can't tell for sure. I also do not want to reinstall the OS as it warns me the current OS is newer than one being installed and I could lose everything!

2) For some reason, I cannot get the USB 2.0 driver to load on this system. In other words, although the PCI card is USB 2.0 compliant and (I thought) MS Windows XP Pro SP2 supported USB 2.0, the card acts as a USB 1.1 device. Is this because of the motherboard or the BIOS? Can anyone explain this to me?

Any help for these problems would be most appreciated! Thanks.

Did you check the jumper settings on the devices? Is the driver for XP and signed?

Sorry its taken me so long to follow up on this thread; I've been away. But the problem remains! htmlman: jumper settings and drivers are fine. The computer sees the drives -- it just won't read any media until a reboot (with the media inserted). This happened with an old CD writer/ DVD combo, an old CD Rom, as well as the two new Sony CD/RW-DVD-Rom Drive and a Samsung DVD +/- R/RW drive. The problem just began and I can't tell what initially caused it.

Could it be that I did not uninstall the original drives before replacing them (even though the problem pre-existed)? How about the BIOS settings? Registry problems? Soemthing inherent with XP?

Please help!

You might try SFC. If you have updated and ran scans of your anti virus and malware programs.
