Usb Device Descriptor Failure Driver For Mac
The USB Selective Suspend option is a power saving option that suspends power supply to selected USB port in an idle state without affecting other USB operations and USB ports. This feature could be a reason behind Unknown USB Device (device descriptor request failed) error.
Since most computer users utilize all sorts of USB devices, this error can be frustrating. When you need to access essential data inside your USB devices, getting a device descriptor failure or a Generic USB Hub error message can easily cause delays.
In this method, we will try to fix the issue by uninstalling and reinstalling the drivers for USB Root Hub devices under Universal Bus Controllers. Windows will automatically reinstall the drivers once you reboot the computer. Follow these steps to perform to complete the method.
One potential reason your device descriptor request may fail is that the device is not properly enumerated. This means the bus driver does not have information about the device, which needs to send a device descriptor request. Another potential reason is that the device is not plugged in correctly or receiving power.
The request for the USB device descriptor failed because the computer did not recognize the USB device. Various factors, including a faulty USB cable, an incorrect driver, or a problem with the USB device itself, can cause this.
In the device's Properties dialog box, click the Driver tab, and then click Update Driver to start the Hardware Update Wizard. Follow the instructions to update the driver. If updating the driver does not work, see your hardware documentation for more information.
Note You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor's website.

However, sometimes, it will open the New Hardware Wizard which may ask for the driver.

The device is installed incorrectly. The problem could be a hardware failure, or a new driver might be needed. Devices stay in this state if they have been prepared for removal. After you remove the device, this error disappears.
A duplicate device was detected. This error occurs when a bus driver incorrectly creates two identically named sub-processes (known as a bus driver error), or when a device with a serial number is discovered in a new location before it is removed from the old location.
Windows cannot apply all of the properties for this device. Device properties may include information that describes the device's capabilities and settings (such as security settings for example). To fix this problem, you can try reinstalling this device. However,we recommend that you contact the hardware manufacturer for a new driver. (Code50)
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
This is an intermittent problem code assigned while an ACPI reset method is being executed. If the device never restarts due to a failure, it will be stuck in this state and the system should be rebooted. 2ff7e9595c
