Port I/O device driver error

[sofia laureano]

Hi there,

I have been getting this message everytime I am running a task and
want to send markers through the parallel port:


Run-time Error (Line 654) 10055: Unable to communicate with the port I/
O device driver

Error: 0x00000000

Please ensure the Port I/O device driver is installed


The task works perfectly on a similar computer (same model).
In the windows XP device manager, the port is listed as "working
properly", and all the settings are equal to those on the computer
where the task runs without errors.

Any ideas would be more than welcome!

Thanks,
Sofia

Sofia,

First, just to be sure we are talking about the same thing, open up
the Windows Device Manager (using your favorite method) on both
computers. Look down the tree to a branch labelled "Other
devices". Open that branch. You should see a branch labelled "PST
Port I/O Driver" on both computers. If you do not see that on the
troubled computer, then it does not have the driver installed.

Anyway, you probably need to repair or reinstall the Port I/O
driver. As it turns out, this error message and several other common
ones are listed in PST Knowledge Base article #3000, a good reference
for us all to look at first in the future (you will have to log in as
a registered E-Prime user). I don't think PST will mind if I just
post the entry for your error, so I will spare you the trouble in
just this case:

"The port driver is needed for read/write port calls and for using
the Port Device. Try running a repair on your E-Prime installation
(via the Add/Remove Programs utility in Windows Control Panel), and
also run the PortDriverInstaller.exe file to install the port driver.
You can download the PortDriverInstaller.exe from the User's Area by
clicking the Download/Misc links. Then restart your machine and try
running again (note this file will not work under Windows 98/ME)"

Hi David,

Thank you so much for your great reply!

I’ve done what you've recommended, but when I try to run the
PortDriverInstaller.exe I get this Warning:

The software you are installing for this hardware: PST Port I/O Driver
has not passed Windows Logo testing to verify its compatibility with
windows XP.
Continuing your installation of this software may impair or
destabilize the correct operation of your system either immediately or
in the future. Microsoft strongly recommends that you stop this
installation now and contact the hardware vendor for software that has
passed Windows Logo Testing.

Continue Anyway / STOP installation

What do you reckon I should do?

Many thanks,
Sofia

Come on, live on the edge, install that unverified driver!

No, the deal is, companies can get Microsoft to verify a certain driver, which they will do after testing it a lot, which, of course, doesn't come cheap. I'm sure most drivers are 'unverified', but what is more remarkable, is that in certain cases, windows xp (perhaps an old version, I think in Dutch) will tell you 'this driver is not digital', which we always thought was a most interesting phenomenon.

Anyway, if you're really scared, back up your system, press "OK anyway" and run!
Best,
Mich

Thanks Mich, you said it better that I
could. Yes, definitely "Continue Anyway".
