 REQUIREMENTS
 
 A host with a USB port.  Ideally, either a UHCI (Intel) or OHCI
-(Compaq and others) hardware port should work.  However, I've only
-been able to really use an OHCI controller.  At the time of this
-writing, both uhci and ohci work with scanner.c *except* for the HP
-4100C which only works with ohci.  This problem is being investigated.
+(Compaq and others) hardware port should work.  At the time of this
+writing, there are two UHCI drivers and one OHCI.
 
 A Linux development kernel (2.3.x) with USB support enabled or a
 backported version to linux-2.2.x.  See http://www.linux-usb.org for
