Problem with burning

hello All,
I have a problem .
I try to burn a dvd. I use an _NEC dvd_rw nd-2510A usb device from Lacie. I get always an error “SCSI aborted …”. I have an Notebook from toshiba with celeron 1.5Ghz. For usb2.0 I use a combo PCMCIA card (2usb2.0 + 2firewire, Ali chipset). Has somebody an idea what to do?
Actually, if I use usb1.1 it works fine but too long.
I’ve just installed windows xp and roxio burn software - it is the same situation.
I’m really tired with it…
With respect,

could be any number of things. have a read @
