When you attempt to install Windows XP on a computer that has a USB floppy disk drive connected, and press F6 to install mass storage drivers from a floppy, the USB floppy drive does NOT work.

The Windows XP installation supports a limited number of USB floppy disk drives, which are included in the Txtsetup.sif file:

<b>Plug and Play ID        USB floppy disk drive model</b>
USB\VID_03EE&PID_6901   Mitsumi
USB\VID_057B&PID_0000   Y-E Data; Sony part number 09K9835
USB\VID_0644&PID_0000   TEAC; IBM option part number 27L4226, FRU 05K9283
The following USB floppy disk drives are NOT included in the Txtsetup.sif file:
<b>Plug and Play ID        USB floppy disk drive model</b>
USB\VID_03F0 &PID_2001  HP  
USB\VID_054C &PID_002C  Sony  
USB\VID_057B &PID_0001  Y-E Data  
USB\VID_0409 &PID_0040  NEC  
USB\VID_0424 &PID_0FDC  SMSC
If you cannot use a supported USB floppy, you can use RIS ( Remote Installation Service) to deploy Windows XP, using the same procedure that I documented in How can I add an OEM NIC to a RIS installation to add mass storage drivers.
