Now select “Let me pick from a list of device drivers on my computer” option. Select “Show All Devices” from the drop-down menu. Click over the “have disk” button. Enter the path for the Google USB driver. C: Program Files (x86) Android android-sdk extras google usbdriver. Method 3: Reinstall The USB Device Driver. If you are fed up with the problem of device descriptor request failed, then uninstall and reinstall the USB device driver from the Windows Device Manager to rectify the issue. Type Device Manager in the Windows search box and click on it to launch the Device Manager.
If you see a yellow exclamation mark next to one of your PCI drivers listed under Other devices or Unknown devices in the Device Manager, and you have no idea what to do, you’re not alone. Many Windows users are reporting about this problem. But no worries, it’s possible to fix, however horrifying the scene looks.
Here are 3 solutions for you to choose.You may not have to try them all; just work your way down until you find the one works for you.
What is PCI device driver?
PCI stands for Peripheral Component Interconnect. The PCI device you see in Device Manager indicates the piece of hardware that plugs into your computer’s motherboard, such as PCI Simple Communications Controllers and PCI data Acquisition and Signal Processing Controller as shown in the above screen shot. These are the hardware devices that keep your PC running smoothly.
If these device drivers fail to work properly, your PC suffers.
How do I fix it?
Note: The screen shots below are shown on Windows 7, but all fixes apply to Windows 10 and Windows 8 as well.
Method 1: Update PCI device driver via Device Manager
Method 2: Update PCI device driver Manually
Method 3: Update PCI device driver Automatically (Recommended)
Method 1. Update PCI device driver via Device Manager
The yellow exclamation mark next to certain device problem can usually be fixed with an appropriate and matched device driver.
1) On your keyboard, press the Windows logo key and R at the same time, type devmgmt.msc and press Enter.
2) If you can see clearly the name of the PCI device as the screen shot shown below (PCI Simple Communications Controller), just go to the manufacturer website of your computer and search for the exact driver from there.
If the computer is assembled by yourself, which means that there is not a definite manufacturer that you can turn to, you can use Driver Easy to help you download the drivers needed for free.
Method 2. Update PCI device driver Manually
If you are not sure which manufacturer website to turn to, you can use the hardware ID to search for the correct driver for you:
1) On your keyboard, press the Windows logo key and R at the same time, type devmgmt.msc and press Enter.
2) Expand Other devices. Double-click PCI Device.
3) Go to Details, select Hardware Ids from the drop-down box.
4) Now, let’s try the first ID listed here first. Copy the first hardware ID listed.
5) Paste it to the search box of the searching engine. Please also add key words such driver or your operating system.
6) Download the correct driver from the list provided. Then you need to install them as instructed by the driver provider.
Method 3. Update PCI Driver Automatically (Recommended)
If you don’t have the time, patience or computer skills to update your drivers manually, you can do it automatically with Driver Easy.
Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):
1) Downloadand install Driver Easy.
2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click the Update button next to the flagged PCI device to automatically download and install the correct version of its driver (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version– you’ll be prompted to upgrade when you click Update All).

Important
You can find a list of known IDs used in PCI devices at The PCI ID Repository. To list IDs on Windows, use devcon hwids *.
The following is a list of the device identification string formats that the PCI bus driver uses to report hardware IDs. When the Plug and Play (PnP) manager queries the driver for the hardware IDs of a device, the PCI bus driver returns a list of hardware IDs in order of increasing generality.
Where:
v(4) is the four-character PCI SIG-assigned identifier for the vendor of the device, where the term device, following PCI SIG usage, refers to a specific PCI chip. As specified in Publishing restrictions,
0000andFFFFare invalid codes for this identifier.d(4) is the four-character vendor-defined identifier for the device.
s(4) is the four-character vendor-defined subsystem identifier.
n(4) is the four-character PCI SIG-assigned identifier for the vendor of the subsystem. As specified in Publishing restrictions,
0000andFFFFare invalid codes for this identifier.r(2) is the two-character revision number.
c(2) is the two-character base class code from the configuration space.
s(2) is the two-character subclass code.
p(2) is the Programming Interface code.
Examples
Note
In these examples, you'll need to replace the placeholder SUBSYS values of 00000000. As mentioned earlier, 0000 is invalid for the v(4) and n(4) identifiers.
The following is an example of a hardware ID for a display adapter on a portable computer. The format of this hardware ID is PCIVEN_v(4)&DEV_d(4)&SUBSYS_s(4)n(4)&REV_r(2):
PCIVEN_1414&DEV_00E0&SUBSYS_00000000&REV_04
The following is the hardware ID for the display adapter in the previous example with the revision information removed. The format of this hardware ID is PCIVEN_v(4)&DEV_d(4)&SUBSYS_s(4)n(4).
PCIVEN_1414&DEV_00E0&SUBSYS_00000000
Note
In Windows 10, some IDs that previously appeared in the Hardware IDs list now appear in the list of Compatible IDs.

Reporting compatible IDs
The following is a list of the device identification string formats that the PCI bus driver uses to report compatible IDs. The variety of these formats provides substantial flexibility to specify compatible IDs. The PCI bus driver constructs a list of compatible IDs based on the information that the driver can obtain from the device. When the PnP manager queries the driver for the compatible IDs of a device, the PCI bus driver returns a list of compatible IDs in order of decreasing compatibility.
Where:
The definitions of the following fields in a compatible ID are identical to the definitions of the corresponding fields that used in a hardware ID: v(4), r(2), c(2), s(2), and p(2).
d(4) in the DEV_d(4) field is the four-character vendor-defined identifier for the device.
d(4) in the DT_d(4) field is the four-character device type, as specified in the PCI Express Base specification.

For the example of a display adapter on a portable computer, any of the following compatible IDs would match the information in an INF file for that adapter:
