BASIC Stamp Not Found - USB

McRat

Greetings,

I did several searches on here before posting, because I'm sure it's something simple, but here goes:

Professional Development Board with BS2 works excellent on Win98 notebook through conventional COM port.
But I need to "retire" this computer.

There are two other notebooks here, neither with COM ports, so I'm attempting to use USB-to-serial driver.· I disconnected the COM cable and use a regular USB cable.

Windows can "see" the board and identify it as a FTDI USB Serial Converter·device.

One computer is XP, the other is Vista.· Best I can do is "BASIC STAMP NOT FOUND".· The IDENTIFY command can "see" the board, and some USB ports net YES/YES, others NO/YES. and others YES/NO.· None will connect.· Used both the Parallax Page USB drivers as well as WINDOWS UPDATE drivers.

Well, after 3 days I'm no closer than when I started.·

Is there a document I need to read?· A switch?

The Windows Update drivers simply do not work. You must uninstall them and install the FTDI drivers (before you plug in the USB-to-Serial adapter).
If the Identify command in the Stamp Editor can see the board, you ought to be able to download to it since the Stamp has to actively identify itself to the Editor. There's a link from the USB driver page for a troubleshooting document: www.parallax.com/Portals/0/Downloads/docs/prod/ftdi/USBDriverTroubleshooting-V1.0.pdf. Personally, I've not had a problem under XP with any of several FTDI adapters.

Thanks!

Well after following that link, it seems I'm out of luck.

I have installed various other FTDI chipset devices (engine tuning systems - EFILive/HPTuners/SPS) on these two computers. The FTDIClean utilities will remove the registry entries for the other devices, but the FTDIClean utility for the Parallax board gives a "File Access Denied". It can't remove the driver to start from scratch.

I will go hunting for another computer around the shop tomorrow and try it again.

Kinda makes me long for the CONFIG.SYS days. You would just tune the computer instead of throwing it away if the software was messed up.

McRat,

Which PC did you try the removal utility on, Vista or XP? In the interest of being 100% sure your system works, have you tried it again on the original Serial Interface using the same supply?

I continued to play with various versions of FTClean on both the XP computer and Vista computer.

Neither computer will accept FTDI devices any longer, even the ones that already ran.

There was:

• Generic FTDI USB/232 device for using General Motors SPX/OTC Tech2 SPS Programming
• FTDI chip device "EFILive" for·GM engine computer programming and datalogging

both working in correctly prior to attempting to communicate with PDB via USB.

This is not a Parallax problem, it's a Windows problem.· Now Windows is telling me the CAN'T LOAD DRIVER, NOT DIGITALLY SIGNED, which is erroneous as most Microsoft errata messages are.· Why can't they just admit it?· -

"CAN'T LOAD DRIVER - We are sorry, but we don't know why our O/S is busted.· But we will fix it with the release of Windows SuperX Extreme Mega Epsilon Professional Service Pack XXIII, we promise!"

OPPS!! Yes, the Win98 computer still talks to the board via RS232 just fine. The XP/Vista computers don't have COM ports.

Make sure when in device manager you see the "unused devices" and delete all of the usb devices and virtual serial ports.
