- use #if BX_SUPPORT_CDROM instead of #ifdef LOWLEVEL_CDROM
- devices with cdrom support now use the base class cdrom_base_c
- cdrom count variable moved to cdrom.cc
- cdrom_misc.cc: don't use ioctl's for ISO files
add the LGPL to usb_hid.cc
- moved Ben's comment to usb_uhci.cc, since this file contains most of his
initial pciusb patch
- TODO: implement full USB keyboard support (port from QEMU)
