dvd player? laserjet printer (with keyspan adaptor)?

[{ brad brace }]

Is there a DVD player?

Apparently I need to "reconfigure the kernel" in order to get my HP 
Laserjet printer to work in conjunction with a Keyspan QuickNet/USB 
adaptor. Has anyone done this who would provide some pointers?

TIA

(I imagined that when I paid for YDL 4 installation support, it might 
actually be helpful. Waste of money.)
