DOS启动盘 & LOGO技术（启动盘室） » Please clarify the specific context or relevant technical details about USBCD.sys and USB_CD.sys so that I can provide a more accurate translation and comparison. As it is now, the question is a bit too general. Please supplement relevant information if possible.

USBCD.sys and USB_CD.sys both seem to be driver files for USB CD-ROM drives under DOS. However, I don't have a USB CD-ROM drive to test, so could you please tell me what the differences are between these two files exactly? Which one is better?

USBCD.SYS is the driver for SCSI CD-ROM drives, and adding USBASPI in front of it supports USB CD-ROM drives. USB_CD.SYS only supports some (mainly IBM) USB CD-ROM drives.
