When you plug the device into your USB, Windows will look for the associated driver, if it cannot find this driver then you will be prompted to insert the driver disc that came with your device. Common USB Device errors are ‘ usb port not working ‘, ‘device descriptor request failed error’ or ‘bugcodeusbdriver’ issues.
This topic is intended for OEMs who want to build a Windows 10 system with USB Type-C connector and want to leverage OS features that allow for faster charging, power delivery, dual role, alternate modes, and error notifications through Billboard devices.
A traditional USB connection uses a cable with a USB A and USB B connector on each end. The USB A connector always plugs in to the host side and the USB B connector connects the function side, which is a device (phone) or peripheral (mouse, keyboard). By using those connectors, you can only connect a host to a function; never a host to another host or a function to another function. The host is the power source provider and the function consumes power from the host.
The traditional configuration limits some scenarios. For example, if a mobile device wants to connect to a peripheral, the device must act as the host and deliver power to the connected device.
The USB Type-C connector, introduced by the USB-IF, defined in the USB 3.1 specification, addresses those limitations. Windows 10 introduces native support for those features.

Hardware design
USB Type-C connector is reversible and symmetric.
The main component are: the USB Type-C connector and its port or PD controller that manages the CC pin logic for the connector. Such systems typically have a dual-role controller that can swap the USB role from host to function. It has Display-Out module that allows video signal to be transmitted over USB. Optionally it can support BC1.2 charger detection.
Consider recommendations for the design and development of USB components, including minimum hardware requirements, Windows Hardware Compatibility Program requirements, and other recommendations that build on those requirements.Hardware component guidelines USB

Bring up drivers
USB Function driver bring-up is only required if you support USB Function mode. If you previously implemented a USB Function driver for a USB micro-B connector, describe the appropriate connectors as USB Type-C in the ACPI tables for the USB Function driver to continue working.
For more information, see instructions about writing a USB Function driver.
USB Role-Switch driver bring-up is only required for devices that have a Dual Role controller that assumes both Host and Function roles. To bring-up the USB Role-Switch driver, you need to modify the ACPI tables to enable the Microsoft in-box USB role-switch driver.
For more information, see the guidance for bringing up the USB Role Switch Driver.
A USB Connector Manager Driver is required for Windows to manage the USB Type-C ports on a system. The bring-up tasks for a USB Connector Manager driver depend on the driver that you choose for the USB Type-C ports: The Microsoft in-box UCSI (UcmUcsiCx.sys and UcmUcsiAcpiClient.sys) driver, a UcmCx client driver, or a UcmTcpciCx client driver. For more information, see the links in the preceding section that describe how to choose the right solution for your USB Type-C system.

| Descripton |
The USB Device Tree Viewer, short UsbTreeView is based upon the Microsoft 'USBView' sample application found in the Windows Driver Development Kits and now standalone at GitHub.
But it is source code only, there is no executable for end users provided. Meanwhile USBView comes as executables as part of the 'Debugging Tools für Windows', see here: USBView. UsbTreeView started with the USBView source code from the DDK for Server 2003. Here are the improvements I've done: - Informations from the Windows Device Management are collected and matched with the found USB devices; Therefore UsbTreeView can show the child devices, including drive letters and COM-ports
- Window position is saved
- Background color and font of the right pane can be set (the font shown in the screenshots is DOSLike 7)
- Keeps the tree item selection over refresh
- TreeView highlighting of arrived and removed devices
- Shows open handles on failed safe removal
- Way more descriptors are decoded, as Audio 2.0
- Hexdump of the descriptors can be shown
- Safe removal, device restart and port restart
- Extended USB information available under Windows 8 and 10 (taken from the latest USBView sample application)
- Extended information about host controllers
- Failed USB requests are re-tried in the background, e.g. if a USB mouse was moved while requesting its properties
- Toolbar with jump-lists for easily finding devices in complex trees
- TreeView with handmade 16x16 icons, USBView used 32x32 icons scaled down to 15x15
- many minor improvements
With V3.0- No more enumeration of all devices on arrival and removal of a USB device
- Search function (not full text, only things like device ID, drive letter, volume name etc)
- Some new Keyboard shortcuts (Alt+D to open the drives list, Alt+O the Others list, Alt+S to focus the search edit, Alt+Left/Right to cycle thru the search hits
- Options not to expand empty hubs or hub with only empty hubs attached
- Options to jump to arrived and removed devices
- Option to expand tree items to make selected arrived and removed devices visible
- Option to rename tree items (press F2 or single-click it when selected)
- Uses Windows visual theme with option to turn it off
With V3.3- Can write and read a report in XML format (not compatibel with USBview's)

USB 1.1
Here we have an old XP Computer with one single USB 1.1 host controller. As every USB host controller it has exactly one USB root-hub. The root-hub has two ports, at port 1 there is a USB mass storage device attached which is mounted at drive letter Z:. Even the USB drive is USB 2.0 it is running at Full-Speed only because it is attached to a USB 1.1 hub.
USB 2.0
Here we have Win7 Computer with an Intel P35 chipset which has 8 USB 2.0 High-Speed capable ports. The 8 physical ports are split here: 4 USB 1.1 controllers deal with USB low and Full-Speed devices while one USB 'Enhanced' controller deals with the High-Speed devices. I don't know why the 1.1 ports are split over 4 controllers with 2 ports each. Since all manufactures do this, there must be a good reason...
The USB High-Speed controllers usually have the keyword 'Enhanced' in their device name. Since Vista the 'USB Hub Capabilities' can be checked for the 'HighSpeed' flag.
At port 1 of the Enhanced controller there is a USB High-Speed hub attached and at his port 4 there is a USB mass storage device attached which is thanks to USBDLM mounted at drive letter Z: again. Here it is running at High-Speed.
Newer Intel chipset have no more USB1 root hubs. Instead there are two integrated standard hubs which translate Low and Full-Speed into High-Speed. Intel calls them 'Integrated USB 2.0 Rate Matching Hub'.
USB 3.0
Here we have a Win8 Computer with a Texas Instrumens TUSB7340 USB SuperSpeed controller card. Windows 8 has native support for USB 3.0 SuperSpeed and an enhanced USB stack which delivers more information, e.g. which speed each port supports. Therefore UsbTreeView can show a 'H' in the icon of the high-speed ports and an 'S' for the SuperSpeed ports. Still missing is the information about the supported SuperSpeed (5, 10 or 20 GBits/s)
The TUSB7340 has 4 physical ports. 4 logical ports are for low, full and high-speed devices and another 4 for SuperSpeed devices. Windows 8 also delivers information about which logical ports belong together. In the screenshot you see that the selected port 4 has the CompanionPortNumber 8, this means that port 4 and 8 share the same physical port.
USB 3.0 Hub
USB3 hubs are in fact two completely independend hubs, one for SuperSpeed and the other one for High, Full and Low-Speed devices.
The only thing in common is that both appear connected to ports which are mutual 'companion ports'.
Here port 20 is the companion port of port 9 and vice versa:
A USB3 device first tries to establish a stable communication with the USB3 port. If that fails (for instance because of a too long or too bad cable) then it tries the USB2 HighSpeed connection which usually works then because its electrical requirements are much lower.
Intel Series 8 xHCI Controller
Here we have a bunch of yellow exclamation marks on a Intel Series 8 xHCI controller on a Asus H81-Plus board. Its ports 11 to 15 have a connection status 3 'Device general failure' which leads to the yellow exclamation marks in the tree view.
Intel's xHCI controllers are quite flexible and need a correct initialisation by the mainboard's BIOS. I don't know this is Intel's or the BIOS maker's fault. As long as all physical ports work as expected this is a cosmetic problem.

| Identify simple BadUSB Devices |
Simple BadUSB devices are USB composite devices, so they keep their usual functionality but have an additional 'bad' function as a keyboard or a network adaptor.
By means of UsbTreeView you can check: The BadUSB device demonstrated by Adam Caudill and Brandon Wilson at github.com looks like this: Note that it is a Composite Device, that is has two child devices - the expected disk and the potentially bad keyboard. A regular USB drive look like this: USBDLM can ask on arrival of a new keyboard or network device if it shall be activated:
