[rescue] Solaris 8 on Sun Blade 150, USB keyboard bug no terminal cursor key motion.under CDE 1.4.

[The Aldridge family]

Hi,
 B B B  Solaris 8 on Sun Blade 150, USB keyboard bug no cursor key motion 
(just scan codes on screen) under CDE 1.4
regardless of the setting of cursorkey mode in terminal options. Some on 
console and with a command line login.

Is this a know problem/bug?
or has anyone seen this bug before?
If known is it a hardware or software bug?
And is there a known fix for it please?
As far as I can test the keyboard cursor keys function normally
under OpenWindows leading me to think it is a bug in CDE 1.4
Any help / advice much appreciated.
73s,
