Latest Windows 10 update is causing USB accessory issues

Some Windows 10 users have reportedly been experiencing problems with their USB accessories after installing update KB5049981, which was released on January 14.

Specifically, affected users are encountering this error message: “This device cannot start. (Code 10). Insufficient system resources exist to complete the API.” As reported by Windows Latest, the issue appears to be rooted in a bug where the USB DAC doesn’t load.

After installing update KB5049981, DACs stop working on Windows 10 PCs and show an error in the Device Manager. If you’re affected by the issue, you should uninstall the update and wait for a fix. If you haven’t yet installed the update, you may want to hold off for a while.

This isn’t the only issue, by the way. Other users — though to a lesser degree — have been reporting issues with Wi-Fi connectivity, with the System Guard Runtime Monitoring Broker Service, with the Snipping Tool, and other stray blue screen crashes.
