I am trying hard to get my Colorado D600 (30Bit) working with
primax_scan-0.93. However, I get the following error message after
port_probe(port) in function epp_on:

| ####@####.#### >./primax_scan -l on
| parse_options:
|  lamp:                 on
|  dimension:        425x585 pixel

My AMI-Bios supports two parallel port modes: SPP/EPP
and ECP. I've tried both of them with the same result.

For SPP/EPP mode port_probe returns a value of 1 and for
ECP mode it returns 19. Both values are obviously
!(port_feature & 0x300) and the program exits.

I am running Kernel 2.2.13 with modular parport support.
I tried with and without loading the parport modules
before running "primax_scan -l on" but to no avail.
After "modprobe parport_pc" there is a message in /var/log/messages:

| ####@####.#### >tail /var/log/messages
|
| [...] anna kernel: parport0: PC-style at 0x378 [SPP]

when in SPP/EPP mode and

| ####@####.#### >tail /var/log/messages
|
| [...] anna kernel: parport0: PC-style at 0x378 [SPP,ECP,ECPPS2]

when in ECP mode, respectively.

It seems to me that the linux parport driver doesn't recognize 
the EPP capability when in SPP/EPP mode, right?

So I desperately switched to ECP mode in the Bios setup, commented out
the exit(1) statement in the (!(port_feature & 0x300 )) if-block, rebuilt
the program and let primax_scan try to switch to EPP mode:


| ####@####.#### >./primax_scan -l on
| parse_options:
|  lamp:                 on
|  dimension:        425x585 pixel
| parse_options:       switching lamp
|
| This Port supports not the  EPP-Mode

| Scanner did not switch to EPP mode.....not compatible?

That's where a long story ends. I feel tempted to give up
unless there is anybody out there who can give me some
advice on how to proceed. Do I have to wait for SPP support
and let the scanner get covered in dust in the meantime?

Thanks in advance.

PS: I have also unplugged my printer which is usually connected
to the pass through of the scanner.
