I have been using a Lexicon Lambda USB mixer on a Windows XP computer for several years. Recently I got a new computer running Windows 7 (64-bit) with a Maximus IV Gene-Z motherboard. I used the install disk to install the drivers, but when I plugged in the USB for the Lambda device, my system kept connecting and disconnecting (with the little connect/disconnect chime each time). I downloaded and installed the Windows 7 drivers from the Lexicon site, and the same situation occurs. When I load the Hardware and Devices window in Windows 7 I keep seeing "Unknown Device" appear and disappear in the window. I've tried this in several USB plugs, all with the same results. I've scoured the forums and found no reference... I'm at the end of my rope! I hope you might have some suggestions on how I can resolve this (I gotta be able to record on this machine for my freelance work). Thank you in advance...

Hi
every driver related problem can be solved by using this software: Driver Update Software.

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!

Make sure the usb socket is working ,the lamda takes current from your computer.Don't use a usb hub.Make sure you are using xp service pack 2 or higher.Try another usb socket.

I have a Sterling st-51 condenser mic and purchased a Behringer xenyx 1002b mixer. Similar problem, dynamic mics work in low impedence with or without phantom pwr on. My Washburn acoustic bass with preamp in line input section. So I tried it on my Omega Lexicon interface. The condenser mic and everything else works on the Omega. This unit has a wall wart ( your Lambda is USB powered). I checked the voltages with a meter and found 23 volts from the mixer and 48 volts from the Omega. Further, I have two Shure SM-82 line mics which work on the mixer with the inputs turned all the way down but do not work on the Omega nor on my Spirit SX mixer which has 48 volts phantom power. The SM-82s are old line mics that have a 9.6 volt battery in the sleeve. They overload badly in all but the 1002B mixer. Their voltage should run btwn the 9.6 battery or a 22 volt phantom power.

Check your Lambda voltage, It could be way less than needed by the st-51. I will check with a friend who has the Lambda and check its voltage. Bet it is too low.

Again, My St-51 and 1002B mixer combo barely works at 23volts, the Mic gain is all the way up as is the channel slider and the main output slider. I cant get any reading on my led meters, occasional bump on the first light, no possible way to clip the input or the output and have to turn the high eq off and the mid way back due to hiss noise. Hope this helps,couldn't find minimum voltages on the ST-51 as yet.

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.

Are you running Vista? Lexicon is working on some firmware and software updates to fix the problem. The only workaround is to unplug and replug your USB cable when it stops working. As long as you are actually using the Lambda, it should work.

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.

Hey robert I can help. What model Imac do you have and Lexicon do you have?? Please let me know.
