BSOD Problem

[MaD2ko0l]

Hi,

Have been rebuilding a new LCD Screen, nothing special just a 2x16 via a USB FT245 chip.

I have rebuilt this 3 times now to get it to work.

So i have rechecked the connections this morning and have got it to work now.

After about 10-15 min whith it plugged in, it will BSOD with an error of "IRQL_Not_Less_Or_Equal"

Now i have installed the latest FTDI drivers.

Anyone have any ideas what is causing this?

If theres anymore info you need plase let me know because i havnt got a clue what im doing.

Are you still having trouble after updating the drivers?

If not, there's a chance you still have a faulty connection somewhere, and even a chance that the USB module is damaged.

First thing to try is remove the drivers and force a re-detection. Open up Device Manager (somewhere under Control Panel > System depending on your Windows version) and look for the FT245 in the device list (I think the device name depends on the exact module model), right-click and uninstall. Then unplug the device (maybe also reboot) and try reinstalling.

FTDI also have some install/uninstall advice at http://www.ftdichip.com/Support/Documen ... Guides.htm

thanks for the reply.

i already did the uninstall of the drivers but didnt solve the problem.

i think i will try a rebuild (again) and see what i can come up with.

If you have any more ideas, please let me know.

Try to install the previous version of the driver. V 2.06.xx works for me, 2.08.xx doesn't.

With 2.08.xx driver my PC hangs after 20-30 mins of work.
