Add Hardware wizard

Glenn · Mar 16, 2003

I get the following error message while trying to install additional hardware. "Cannot Run Two Device Installations. You can install only one device at a time. Another device installation is underway, when it is finished you can try this wizard again."
I am unable to install any additional hardware until I fix this problem. Help would be much appreciated.

And the hardware would be?

It sounds like Windows has detected a device and is attempting to install the necessary drivers, and you tried to do the same thing at the same time with the Add Hardware wizard.

I'd suggest removing the device and rebooting. Then set the Device Manager to show all hidden devices, as illustrated on this <A HREF="http://www.winguides.com/registry/display.php/1107/" target="_new">page</A>, and reboot again. Once you are back in Windows, go back to the Device Manager, and choose "Show Hidden Devices" under the View Menu. If you see the device listed you were trying to install, especially if it is listed more than once, delete (uninstall) the device entries. Afterwards, install the hardware again, and give Windows time to locate the device and install the default drivers. You should see an icon on the taskbar that denotes Windows has located a device and is trying to do an installation. Once that has disappeared, (and the hardware appears in the Device Manager ... even if it is not identified exactly (which may happen due to the age of the driver) then you can upgrade the drivers (if necessary) or add software that runs with the device.

Note: The reason I mentioned the Registry Edit is because WinXP really doesn't show all the hidden devices that are listed in the Device Manager, even if you choose the option from the View Menu. But the edit solves that particular problem.

If you'd rather not get into the Registry, you can always download a file that will do the work for you. Look in the right-hand column on this <A HREF="http://www.kellys-korner-xp.com/xp_tweaks.htm" target="_new">page</A>, across from #107. Double-click the file to add it to the Registry, and then reboot.

I hope this helps!

Thank for the reply Toey. Tried what you suggested - This did not help. I have delete all devices from the device manager, not currently attached to my laptop. After rebooting, I go and open ADD HARDWARE, I still get the same error message. My device manager indicates no conflicts. Obviously the hardware wizard thinks it's currently installing new hardware - I need to somehow reset this which I do not know how ??

Did you physically remove the device from the system before removing the entries from the Device Manager? Did you see an "Other" device listing containing information about hardware you don't actually have connected to the computer?

And what, exactly, is the hardware that you are trying to add? The Add Hardware wizard is actually rarely needed in WinXP, so I'd really like to know what kind of device was being installed that Windows would have difficulty detecting without prompting.

Is there any information pertaining to the error in the Administrative Tools Event Viewer logs? (Control Panel\Administrative Tools\Event Viewer\Application and System Logs.)

Answer to your questions:
(1)Yes all devices were removed - they were 19"monitor, misc USB entries, misc mice entries etc..
(2) Device listings look correct.
(3)I am tring to add the modem drivers for my mobile phone. (It's an Ericsson T60C and these drives need to be added manually). This is done via PHONE and MODEM Options within the control Panel - modems tab and ADD option. This is were I get the same message "Cannot Run Two Device etc.."

Note: As part of the setting up of the mobile phone you need to install the relevant drivers for the USB cable that plugs into the mobile phone XP did this without a problem. It is only when I need to action a manual install when I have the problem.

(4) No problems in the event logs.

I am thinking that due to this being the first time I have had to do a manual hardware install, maybe I have always had the problem and I need to contact the company I purchase the laptop from.
Regards Glenn

Update - My event system log does have one warning
Event ID 270 "Plug and Play user-interface dialog have been suppressed in Factory Mode."

I can not find any help on the Microsoft web page.

Here's what I have discovered so far.

Basically, the installation of the phone drivers should not have been necessary ... Windows should have done it without manual intervention from the user. The same thing goes for the cable.

I picked up this information from the <A HREF="http://www.sonyericsson.com/images/spgc/CWS31_GSD_T60c_Advanced_Features_AE_27_0_1090.pdf" target="_new">CWS31_GSD_T60c_Advanced_Features_AE_27_0_1090.pdf</A> guide on the Ericsson website (page 20). All that should have been necessary for the installation was to turn on the phone, connect it to the DCU-10 cable, and allow Windows to detect the cable, which should have been identified as a new serial port called USB Cable DCU-10. The listing would have been under Ports (COM & LPT), where you would have adjusted the Bits per second to 115200 bps, and the flow control to Hardware under the Properties for the port.

The installation would only have been controlled manually if Windows did not detect either device.

Here's what I would suggest at this point. I would uninstall the USB port from the Device Manager, and reboot the system. Then attempt to install the port again, using the above instructions, and see if Windows can handle the installation correctly, automatically.

The reason I suggest removing the cable listing from the Device Manager is because I suspect that the problem doesn't lay with Windows trying to install the phone twice under Modems, but it is instead trying to install the cable more than once, since you tried to manually add the T60c drivers through the Add Hardware Wizard.

If this doesn't work, I'd suggest that you contact Ericsson, since they are the manufacturers, instead of the laptop manfacturer, since they probably will be just as mystified about the problem with Windows as you are. There is very, very little documentation about this error, and no other solutions in sight that I can find.

Question:

I'm looking over the information you posted again, and you stated that Windows installed the USB cable without a problem. So ... is the reason you attempted the manual installation of the modem drivers because the phone wasn't detected, or because it wasn't working?

Sometimes, with USB, a device won't function unless it is turned on and the system is rebooted.

You see, it is also possible that while you were in the middle of manually installing the drivers for the modem, that Windows was also doing the exactly same thing in the background.

Still, uninstalling the cable and allowing the automatic detection is the best option from my viewpoint, without actually being able to see the system. And don't be surprised if it takes more than one reboot for Windows to detect the phone correctly after the cable is installed. be patient, and see if if happens without needing to do anything manually.

Be sure that after you uninstall the cable, that you reboot at least once without the cable attached, and again remove any hidden devices in the Device Manager, specifically under the Ports listing. And if necessary, go into the BIOS, and disable any COM or printer ports that you are not using, just in case of some kind of IRQ or I/O Address conflict between the ports.

Answer.
The reason I was trying to do a manual installation was because the phone wasn't detected. I am happy to say after removing all the relevant devices (for the umpteen time) XP firstly detected the DCU 11 USB cable, and installed drivers, then (with the phone ON) I requested XP to scan for new hardware, on about the 5th time I tried this, it detected the phone modem, from here I am able to install the Ericsson drivers I down loaded from their website. All in All I have achieve my goal.

Note: I still get the same error message when I run ADD HARDWARE. And Yes this also occurs immediately after a rebooting the PC. Thanks very much for for comments.
