USB/RS232 Bridge gives Blue Screen.

original title: USB/RS232 Bridge gives BSOD.

I have a RS232/USB bridge with PROLIFIC drivers that worked fine in XP SP3. It now gives me the blue screen of death after about 3-5 minutes when run as admin. If I run in regular user mode then it locks my software up after nor more than 5 minutes. I then purchased a new bridge that uses FTDI drivers but it still locks up. No more BSOD either as admin or user but locks the program up. This is the text from Windows.

I have also run this app in compatability mode "XP SP3". Still failed.






My best guess is that neither is Windows 7 compatible even if they claim they are. Often makers
will release a product/program intending to fix any issues upon customer complaint. Check with
the maker of the newer one for updates. Remove both sets of drivers and then try the new one
(after checking for updates with makers for new drivers). Isn't the older Prolific model a 1.1
device anyway? Be sure to reboot after removing the drivers before trying new ones.

Here are several methods to remove drivers.

DriverView - Free - utility displays the list of all device drivers currently loaded on your system.
For each driver in the list, additional useful information is displayed: load address of the driver,
description, version, product name, company that created the driver, and more.

How to Remove Old Device Drivers from Vista & Windows 7

Remove Old Drivers After Upgrading to New Hardware

Make sure all the drivers for those have been removed.

Check with a real computer shop to get a product that will work out of the box.

This one has Windows 7 drivers available at the site for download.

Hope this helps.
