USB driver in 2.6 kernel???

[Xiangfei Jia <xjianz@xxxxxxxxx>]

In 2.4, the kernel simualtes IDE CD-ROM and USB devices using SCSI. But
in 2.6, the kernel have been changed to support IDE CD-ROM driectly
without support of SCSI sumulation. 

One thing I'm confused is the USB driver in 2.6. For a usb storage
device, the kernel still use scsi driver to access the usb device , for
example in /dev/sda1. So, this means the 2.6 kernel still support USB
devices with SCSI simulation. Is this right???
