Need some help.

I had been running a burner (NEC 2500a) for the past month or so with no problems on a Dell Inspiron 2650 (laptop). I have it in a USB 2.0 external encasing connected to a usb 1.1 port. It was working fine.

I purchased a USB 2.0 PCMCIA card and installed it. It was still running as 1.1, so I followed their instructions and downloaded the new microsoft driver for the card. after installing the card using the file (had to download from e-machines) it all seemed to be working well. I attempted to backup a ps2 game, yet with the burner plugged into the new card (usb 2.0) dvd decrypter stalled at the lead-in and the burner did nothing. After a few tries, i switched back to my built in ports, and now these are having problems. As i was attempting to burn the dvd, the drive began flashing a orange then green pattern. Then the burn failed. Is there any way i can revert to my old driver and just use it to burn. Even if usb 1.1 makes me burn at .6x Its better than nothing. Any help would be appreciated.

Have you only tried this one dirver, I'd search around for some different drivers. Because it's apparentyl not a faulty PCMCIA card since the buolt ins are failing too.
