I will send it to you if you want, but I have the debug turned on
so it is large (~2 MB). I will first rebuild it with debug off so
it is smaller and check that that works. The other thing you could
check is in the ../h/plustek_scan.h file, near the beginning. Just
before the
#define _OUTB_CTRL.. outb_p...
statements there is an
#if 1 or #if 0 statement.
If it is 0, change it to 1 and rebuild the driver. I would also be
sure the outb (lower case on right hand side of statement) is
outb_p (same for inb -> inb_p). There seem to be timing issues
involved here; I have only had consistent success with the outb_p
statements (they put in a slight delay). Since the /dev/pt_drv do
not seem to be created by the install, you might want to create
them by hand (mknod /dev/pt_drv c 40 0 at least).
