If I use a USB connected hard-disk (IDE), which device driver would I
be using? I understand it is recognized as a SCSI disk. So, is it the
SCSI driver? Or would the IDE driver be used?
Thanks!

You would use the usb-storage driver which in turn uses the scsi driver.

Thanks for the reply Carlos and Eshwar.
So is it that IDE (ide-disk.c) doesn't even come into the picture?

kernel would I find code for read/write on disk?
Thanks in advance.

It would be the SCSI layer running on top of the USB drivers. No IDE
involved on the PC side (obviously the USB enclosure has an IDE
controller, but it's driven by the enclsure firmware, not Linux).
