Lexicon Lambda driver not recognized in Windows 7 64, Lambda is still showing up as a USB composite device.

One of two I was say is the issue.

• When you improperly ejected the card you messed up the MFT (master file table) on the card. You will want to format the card.
• You could have hosed the drivers. In Device manager look under the driver details there should be some files listed. You will probably need to delete these and replace them. Since they may be system files you would need to replace them in a live boot environment such as a linux live boot cd (ubuntu.com) would be the easiest. Get the drivers it has listed copy them to a thumb drive. Boot the computer to the live CD, delete the driver files and replace with the new ones.

It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.

Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.

In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.

Run regedt32.exe and navigate to;

HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb

Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.

A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying .

Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.

Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;

1. USB peripheral devices (printers etc.)

2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.

3. USB Root Hub(s)

4. USB Host Controller(s) (Universal or Enhanced Host Controllers)

Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.

download this manual and see your lambda interface will supported windows vista also i will give you are link download it and see

http://www.lexiconpro.com/product_downloads/8/manuals/Lambda_Install_Guide.pdf

All it needs is a USB connection. You'll need to go into Cubase device setup and make sure your lambda drivers are selected. Then create the audio channels in cubase with the inputs set as the inputs you're using for guitar and mic. There is a monitor button right next to the record enable button that needs to be enabled if you want to hear playback from your computer.

Good luck!

the usb could be the problem. when you plug it in does your comp make a noise if not it is the usb if it does than the drivers are not in sometimes its a program problem try going to start-mycomputer-(cd/dvd drive right click on it and click explore. find the file labled drivers and install them first than install the program hope this helps.

one of several install steps (the steps seem to vary depending on which manual you can find) mention checking your sound device setup in control panel. ON one machine I installed the sound devices were not affeted. On a 2nd PC they were changed from drivers installed with PC to the Lambda driver

Win XP settings->control panel->Sounds and Audio Devices then select Audio tab. Make sure the three areas are set up to use your PC's default drivers and not lambda's.

You may need to verify this again when reconnecting the Lambda USB cable. Sort of new but ran into this "issue" as well.

Found info in Lambda Studio Software Installation Guide I downloaded, step B following driver install.

I have had the same problems with the lambda driver ...they just posted a new installer on the lexicon website which fixed me up...try it.

AFTER you open a new poject go to "Devices" then "Device Setup" click on "VST Audio System" then on he right side where it says "ASIO DRIVER" make the selection say "Lambda ASIO" then click OK

Go to your devices tab click on the ASIO driver Lambda and when you get that message click reset and try again it should work.
