Damn, it’s happened again (just like about 6 months ago). Anyone else seeing a similar problem? ---

Ah, I see this was moved to IMHO. Fair enough. I use my usb interface for music creation, hence the cafe category. But true, it’s more of a general technical issue… ---

What brand of computer? what brand of USB device? Is the problem the OS doesn’t see the device, or your application software. Etc, etc., etc. ---

> [@LSLGuy](#): > > What brand of computer? what brand of USB device? Is the problem the OS doesn’t see the device, or your application software. Details. Dell Inspiron 3910 Windows 11, 10.0. 26200 build 26200 The USB device is a Lexicon Lambda. This is no longer manufactured, and I had to do the trick to install non-signed drivers to get the driver recognized to get it working; this was a year or two ago. This has happened once before. I got round it then by rolling back the update and disabling updates for a while. Eventually a later update restored the function. I can probably use this stopgap again for a while. I realize I am living on borrowed time here: eventually the ‘allow unsigned drivers’ kludge is probably going to fail, and I will have to buy a newer interface… Just wondering if this current problem is specific to the fact that I’m using an older driver, or if it is generic to all USB audio devices? As I recall, the last time this happened, it disabled all USB audio function. Until a later update restored it…? ---

For the cross reference our OP mentioned: > [@Windows 11 disabled my audio interface](https://boards.straightdope.com/t/windows-11-disabled-my-audio-interface/1013916): > > A big update came in a day ago, and now I find that about a minute after reboot, my audio interface stops working. Unfortunately this is an old Lexicon Lambda device which is no longer supported by the manufacturer. I had to go though a rather laborious process of disabling windows driver signature checks to get the driver installed in the first place. But now it looks as if they have upped the ante on unsigned driver checks. I’m guessing that there is some new daemon process which runs afte… ---

Open Windows Security and click on Device Security and then Core Isolation. If your driver was blocked there should be a message there. You can turn off Core isolation, but I don’t advise it. ---

I had a US Robotics dialup USB modem for my PC that I used for years, but Microsoft recently banned one of the drivers for it for security reasons. Those drivers were _ **very** _ old. I had to buy a new modem that used different and more modern drivers. It happens. ---

$48.03 including tax. This was for the [StarTech 56K USB Dial-up and Fax Modem V.92](https://www.walmart.com/ip/StarTech-56K-USB-Dial-up-and-Fax-Modem-V-92-External-Hardware-Based-USB56KEMH2/927478951).

> [@Thumper668](#): > > You can turn off Core isolation, but I don’t advise it. I would, easily. I don’t use it. It reduces performance for a type of exploit that just isn’t common enough unless you are careless with installing drivers and such. I understand the risks, but I trust the outer security (and don’t install enough dodgy software) enough to consider it more of a hinderance. They would be no less secure than they were back before it existed, back when they purchased the device. I’ll let new security features run if they don’t hinder me, but the second it actually matters, I turn them off. So I would easily turn this off if it allowed me to continue using my device. (Though would Microsoft go in and turn it on when it had previously been turned off? I genuinely hope not.) ---

Considering that the problem started with using old drivers, I wouldn’t consider that advisable. Of course what an individual user chooses to turn off is entirely up to them. ---

Ah well. Sometimes one has to bow to the inevitable and accept that trying to keep an old peripheral device limping along is more trouble than it’s worth, even if the device itself is in working order. So I caved in and bought a Focusrite 4i4. Back to recording music again. Hopefully this will future-proof me for a while, since Focusrite seem to be the dominant market leaders in this field…
