Hi qpieus, nice to see you got a SATA drive. Lite-On's are a lot of fun to play with.
I don't think you'll have to configure anything special to use the BenQ on USB. When I first tried running CDSpeed with my BenQ 1625 on SuSE 10.0, it was more of a coincidence (through a particular BIOS setting and SuSE using the old IDE-SCSI module) that it worked. And I had to do something with mount points to get USB to work IIRC. But ever since using an internal SATA drive and openSUSE 10.2, I can use USB and FireWire drives with the standard wine (0.9.53) install (they're all SCSI devices). Even Lite-On/C0deKing Firmware/EEPROM Utilities work, though some update (wine/xorg/nvidia - I don't know which) killed the use of SmartBurn for me... I'll get to try SUSE 10.3 eventually.
Anyway, having CDSpeed make using Linux a lot more fun for a CDFreak
