For Anyone Using A Keyspan USA-19HS USB To Serial Adapter

[Bob]

Hello,

I am running an HP Desktop Pavillion, about 3-4 yrs old, and Windows 7,
the 64 bit version.

My problem relates to trying to get my Keyspan/Triplite USA-19HS USB To
Serial Adapter working again.

I haven't used it for about a year, and am now trying to get it going again.

Have Downloaded what I am pretty sure is the correct Driver/installation
package from their site.
Seems to install just fine, and the Keyspan Folder is under Programs
(x86) where I imagine it should be.

Also, two of the actual Drivers, and two of the .dll also ended up in
the System32 Folder.
Don't understand this, but I imagine it is correct.

Have Downloaded and re-installed, now, several times, bith with and
without the actual unit on the end of the cable.

No matter what I do, in Device Manager the Keyspan icon does show, but
has the yellow "not-good"
mark also. Error msg when I click on it is that it cannot find, or open,
the unit.
Also, essentially the same message appears in their "Assistant" program
to the effect that it cannot locate the unit (even if it is plugged into
the cable).

Have spoken to two of the Keyspan technical support guys. Really nice,
helpful, and apparently really
know the product, but haven't been able to offer anything much more than
the re-tries.
The green LED on the unit never goes on.

So,

Since it seems like it is probably something I am doing wrong, as usual,
(will blame it on old age), I am wondering if you might have anything
specific to suggest that I can try ?
Or, thoughts on what I may be doing wrong ?
Or, ...?

BTW: I can't find the installation CD that came with the unit, so I
downloaded the Driver/Installation download from their site. Do you
think that perhaps the CD had something "more" on it that is essential ?

I'm totally out of ideas.

Much thanks,
Bob

Try uninstalling it with the uninstaller program it should have dumped
in a folder somewhere. Then, reboot and after windows has settled down a
bit, plug it in and see if it "discovers new hardware". Then when it
asks for the drivers (it should) point it in the direction of the
program you downloaded that has the alleged drivers for that exact unit.
Your best bet is to locate the ORIGINAL cd because, as you suspect, it
likely has the exact drivers for that exact version of hardware.

Look to see if there is a uninstall program in the folder that was
created when you installed the driver. If not, do it the hard way.

You have the wrong driver being used. Go to the control panel then
Hardware & sound > device manager. With the keyspan device plugged in
find the Keyspan USB device in the device manager. Right-click
properties. Look at where the file is listed in the device manager make
a note of it.
Unplug the keyspan device then reboot the computer. Now go into File
explorer and to the directory where the file(s) were listed in the
device manager and throw them in the trash. You may be prompted for
administration privileges. Just make sure you put the right file(s) in
the trash. Once you have done that install this file for windows 7:

I use Keyspan 19 and it works fine on Win 7 64 bit, however I had to do
a clean install going from Win XP to Win 7 64 bit, so I don't have any
old drivers hanging around that could confuse windows.
