Cannot remove orphaned com ports !!!!!
Using Vista Home Premium 64-bit, after numerous attempts at installing a USB to serial converter based on the FDTI 232R chip I have the converter working but also have numerous extra com ports (1,2,3,4,5,8,9,10,11,12,14,and 15) that I cannot remove. From Control Panel Printers Right-click anywhere Click on Ports Tab these com ports are visible but when selecting a port and clicking the delete option I get an error message that states "Selected port cannot be deleted. The request is not supported". I also tried to delete using device manager but the extra ports do not show up there, even when using the environment variable 'DevMgr_Show_NonPresent_Devices = 1" and selecting 'Show hidden devices" option in Device Manager. Any help would be appreciated Thanx -- sonerai3 |

Cannot remove orphaned com ports !!!!!
I have the following a batch file and have never had any issues deleting no
longer existant items: You need to right click the batch file and run as adminstrator. ------------------------------------------------------------ set devmgr_show_nonpresent_devices=1 cd %SystemRoot%\System32 start devmgmt.msc ------------------------------------------------------------- Then just select to show hidden devices and the no existant ones appear. -- David Vair CNE, CNA, MCP, A+, N+ "sonerai3" wrote in message ...

Are you using the 64-bit version. Also you run the batch file from the Command Promp correct??? (I am far from an expert on this) Thanx for your response -- sonerai3 |

Cannot remove orphaned com ports !!!!!
Using 32 bit Vista Ultimate.
Copy the text into notepad and save it as whatevername you want.bat The right click the .bat file and select run as adminstrator. It will open the command prompt and the Device Manager will open up. Not sure but you may have to change the system32 portion since you are running the 64 bit. I know you set the environment variable which should have done the same thing but you can double check here to be sure its typed in correctly to the environment variables http://www.vistax64.com/tutorials/16...s-drivers.html -- David Vair CNE, CNA, MCP, A+, N+ "sonerai3" wrote in message ...

I checked the environment variable and it is correct plus also did the batch file routine with the same results. I should point out that hidden devices do show up BUT just not the com ports. Im guessing its something weird about 64-bit or possibly the FTDI chip thats my problem. I suppose I will have to manually edit the registry to delete but I am not sure how to do just yet. Thanx for your help. -- sonerai3 |

Cannot remove orphaned com ports !!!!!
I'm having the same problem with the orphaned com ports but I haven't been able to successfully install the adapter. I was able to remove the com ports from the registry so they no longer show up in the printer- ports tab but the next attempt to install the adapter driver still used the next successive com port (I'm up to com 7 now). sonerai3, can you tell me how you were finally able to install your adapter? -- mrfreeze |

Make sure that you run the driver install file BEFORE connecting converter. The file is CDM 2.04.06.exe from the FTDI website; this file installs the inf files (I believe) from a command prompt window and then when these files are installed and the converter is plugged in the hardware should be recognized and the virtuak com port drivers installed. I can remember if unplugging and re-plugging the converter was successful in recognizing the hardware correctly or not. To be honest with you I just switched back to XP for now. I had the 64 bit version of Vista which absolutely will not work with any drivers that are not digitally signed (32 bit Vista will). This problem made my recently purchased USB oscilloscope and function generator useless plus other Vista problems (hardware recognition being one of them) made me decide to put Vista aside for a while. Good luck!! -- sonerai3 |

Cannot remove orphaned com ports !!!!!
Thanks for the fast reply. In my continued search for a solution I found a driver that worked, or at least seems to. I'll keep your information handy in case I have more problems. I was however unable to figure out how to get the drivers to use a lower COM port. It seems that all COM ports that were used in prior failed attempts are now unavailable. My latest, and hopefully last driver install, is using COM8. Please let me know if you ever get an answer to that problem. -- mrfreeze |

I never did (until going back to XP OS). Once it installs and shows up in device manager you can right-click, select 'Advanced' and then name the port whatever you want I believe. Good luck -- sonerai3 |
