about USB Storage.

I read the tutor written by dazzy.
I have some questions:
1.
dazzy\'s driver -> M$\'s usbstor.sys -> usbd.sys
or
dazzy\'s driver -> usbd.sys
what is right?
2.Is it work on 98?
if 2==true,then only need one driver - dazzy\'s driver?
(becuase I ever c some products that have 2 drivers.)

thx

1.
dazzy\'s driver -> usbd.sys  is right.
because my driver get the IRP_MJ_SCSI MajorFunction from System Storage class driver, there is nothing with M$\'s usbstor.sys.If you wants to write the other usb storage driver, what you do is to process the IRP_MJ_SCSI(with the parameter SRB), IRP_MJ_DEVICE_CONTROL(IoControl code is IOCTL_SCSI_PASS_THROUGH, IOCTL_SCSI_PASS_THROUGH_DIRECT, IOCTL_STORAGE_QUERY_PROPERTY).

It not work on the win98!
becoz the win98 don\'t send IRP_MJ_SCSI to the driver, you must write one storage port driver(IOS) and a usb driver.

you can refer to the M$\'s usms or usbls120 for win 98!

 For details, you can mail it to me!
