Hi all,
I have a twist on the old HP scanner "failure to communicate" problem.
I am running a USB connected 3570c scanner on WinXP Pro. Everything
was working properly a few days ago but now the scanning software will
not initiate contact with the scanner. No new software was installed
by me in the meantime and my AV and malware scanners can find nothing
amiss.
The scanner is normally attached to a USB hub. I have checked all the
ports on the hub using other devices (they all work) and I have tried
plugging the scanner directly into the computer. The scanner continues
to misbehave regardless of where it is plugged in.
Symptoms:
The HP Director module launches but fails to create a window. I can
see it in the Task Manager but nothing is visible and there is no cpu
activity. The executable appears to be hung - it has to be killed
manually. If I try to launch one of the applications directly (like
copy or image scan), I get the infamous
"Failure to communicate with scanner. Be sure scanner is on and
properly connected. [1215]"
error and then the application opens but nothing works. Unlike the
director executable the individual applications do seem to close
properly.
Ok so far? Here's where it gets weird.
Windows (properly) recognizes when the scanner is present - it
appears/disappears from My Computer when I muck with the USB. When
connected, I can open the scanner's property pages and test the device
(whatever that does) successfully and also edit the front panel button
events. When I enable the scanner's buttons to remote launch their
respective applications, the apps work properly when launched by the
driver in response to a button press ... but not when launched directly
from Explorer.
The error is obviously false - the scanner IS communicating and
working. I can use it - but apparently only when the scanner remote
launches the application.
I checked HP's web site and I am running the latest software for my
scanner model. I've tried the Aug 2005 "Comm Failure" patch without
success and I have also tried completely uninstalling the software and
device drivers and reinstalling everything from scratch. So far no
joy.
I haven't seen any useful information in past posts regarding this
problem - most of the responses have either blasted HP or pointed to
the latest driver. AFAICT, no one has previously mentioned seeing apps
work when launched by the driver but not when launched directly.
Has anyone actually resolved the "Comm Failure" issue and if so, how?
Thanks in advance,
George
