依照華碩主機板說明是要先將usb軟碟機品牌製造商的Vid&Pid資料寫入磁片txtsetup.oem檔內，例如
[HardwareIds.scsi.iaAHCI_7RDH]
id = "PCI\VEN_8086&DEV_27C1&CC_0106","iaStor"
#--The following lines give additional USB floppy support
id = "USB\VID_03F0&PID_2001", "usbstor" #--HP
id = "USB\VID_054C&PID_002C", "usbstor" #--Sony
id = "USB\VID_057B&PID_0001", "usbstor" #--Y-E Data
id = "USB\VID_0409&PID_0040", "usbstor" #--NEC
id = "USB\VID_0424&PID_0FDC", "usbstor" #--SMSC
id = "USB\VID_08BD&PID_1100", "usbstor" #--Iomega
id = "USB\VID_055D&PID_2020", "usbstor" #--Samsung
id = "USB\VID_03EE&PID_6901", "usbstor" #--Mitsumi
所以要先把USB軟碟機插到別台電腦，到裝置管理員查看它的VID&PID，這樣安裝XP時才能認的這台軟碟機。
