Indeed there is (usually) a SCSI-emulation layer involved when the installation is from CD-ROM. But the SCSI module questions during installation that the OP referred to, are often a mere symptom: from what I understand the kernel always starts asking for SCSI modules as soon as it can't find the installation CD-ROM. Apparently the kernel concludes that it must be the SCSI layer that is at fault, while often the actual, underlying problem is that the bus where the CD-ROM is attached to (USB, PCMCIA, parallel port, ...), or the bus device driver, hasn't been initialized (properly). In the OP's case that bus is the USB system. From my experience with PCMCIA CD-ROMs (PCMCIA "bus") I remember similar nasty questions about SCSI modules - as soon as the PCMCIA system had been initialized properly (related to proper parameters to the install kernel) the SCSI questions disappeared. In my case(s), the messages shown in the Alt-F4 / Alt-F3 consoles were quite enlightening.... Philip
