Hi,
did anyone see this too?.
I changed my /etc/usbd.conf to have additional entries for a
Microsoft Intelli Mouse with 3 and 5 Buttons and a wheel.
Now the usbd dumps core in read_configuration on line 464 of
usbd.c revision 1.10.2.4.
This seems to be, because of the whitespace and comment checking
part is counting len to zero, while searching for real config
lines and skiping the comments etc. But somehow len now become -1
and obviuosly dumps out in strncpy(linez, line, len)
A patch may be this:
Index: usbd.c
===================================================================
RCS file: /net/ga/home2/ncvs/src/usr.sbin/usbd/usbd.c,v
retrieving revision 1.10.2.4

len--;
}
! if (len == 0) /* empty line */
continue;
if (line[0] == '#') /* comment line */
continue;
--- 449,455 ----
len--;
}
! if (len <= 0) /* empty line */
continue;
if (line[0] == '#') /* comment line */
continue;
Here is my /etc/usdb.conf which causes that trouble.
