Note Because Windows 2000 and Windows XP were released before USB 2.0 hardware was available, the drivers were released for those operating systems in the service packs. To install drivers: • Follow the procedure that was described in the answer to the first question to verify that your computer has USB 2.0 ports and that you need to install a driver for the enhanced host controller. • In the Device Manager window, expand the Other Devices section as explained in the first question, and then double-click Universal Serial Bus (USB) Controller. • On the General tab of the Properties dialog box, click Reinstall Driver. • In the Add New Hardware Wizard, select Install the software automatically (Recommended), and then click Next. Continue with the wizard, accepting all default options, until you reach the last page of the wizard, and then click Finish. You might be required to restart your computer to finish the installation.

Can I disable the 'HI-SPEED USB Device plugged into non-HI-SPEED USB port' notice? Windows XP and later versions of Windows create a pop-up notice when a Hi-Speed USB device is plugged into a USB port that does not support high speed.

To obtain the fastest performance from the device, users must click the notice and follow the instructions on the screen. To disable the notice, follow these steps: • Start Device Manager, as described in the first question in this FAQ.

• In the Device Manager window, expand the Universal Serial Bus controllers node. Look for a host controller with the word 'Universal' or 'Open' in the title. If you find one, double-click it. • On the Advanced tab of the Properties dialog box, select Don't tell me about USB errors. For additional information about USB 2.0 support in Windows XP Service Pack 1, see Microsoft Knowledge Base article 329632, 'How to obtain and to install USB 2.0 drivers in Windows XP Service Pack 1,. Is my USB 2.0 hub single-TT or multi-TT?

A USB 2.0 hub can have one transaction translator (TT) for all downstream-facing ports on the hub (single TT), or it can have one TT for each downstream-facing port on the hub (multiple TT). The value of the bDeviceProtocol field of the USB device descriptor and the bInterfaceProtocol field of the USB interface descriptor indicate whether a hub is single-TT or multi-TT: • Single-TT. BDeviceProtocol == 0x01 • Multi-TT. BDeviceProtocol == 0x02 Usbhub.sys uses this setting to enable multi-TT mode or single-TT mode.

On Windows XP and later, Usbhub.sys always enables multi-TT mode on a multi-TT hub. For additional details about TT layout, see sections 11.14.1.3 and 11.23.1 of the. What characters or bytes are valid in a USB serial number? Augusto Pieroni Leggere La Fotografia Pdf To Jpg more. The USB device descriptor's iSerialNumber field indicates whether the device has a serial number and where the number is stored, as follows: • iSerialNumber == 0x00: The USB device has no serial number. • iSerialNumber!= 0x00: The USB device has a serial number. The value assigned to iSerialNumber is the serial number's string index.

If the device has a serial number, the serial number must uniquely identify each instance of the same device. For example, if two device descriptors have identical values for the i dVendor, idProduct, and bcdDevice fields, the iSerialNumber field must be different, to distinguish one device from the other. Plug and Play requires that every byte in a USB serial number be valid. If a single byte is invalid, Windows discards the serial number and treats the device as if it had no serial number. The following byte values are not valid for USB serial numbers: • • 0x2C.

• Values less than 0x20. • Values greater than 0x7F. For additional details on the iSerialNumber value, see section 9.6.1 of the. What LANGID is used in a string request on localized builds of Windows?

A USB device indicates the presence of a serial number by setting the iSerialNumber field of the USB device descriptor to the serial number's string index. To retrieve the serial number, Windows issues a string request with the language identifier (LANGID) set to 0x0409 (U.S. Windows always uses this LANGID to retrieve USB serial numbers, even for versions of Windows that are localized for other languages.

What LANGID is used to extract a device's serial number? A USB device indicates the presence of a serial number by setting the iSerialNumber field of the USB device descriptor to the serial number's string index. To retrieve the serial number, Windows issues a string request with the language identifier (LANGID) set to 0x0409 (U.S. Windows always uses this LANGID to retrieve USB serial numbers, even for versions of Windows that are localized for other languages. What is the maximum USB transfer size for different Windows versions? How should numbers be assigned to multiple interfaces on a composite device? Windows treats USB devices that have more than one interface on the first configuration as composite devices.

For Windows XP Service Pack 1 and earlier versions of Windows: • Interface numbers must be zero-based. • Interface numbers must be consecutive and increasing. For Windows XP Service Pack 2 and later versions of Windows, interface numbers are only required to be increasing, not consecutive.

For additional information about interface numbers, see. Alternate settings for an interface should be assigned as follows for all versions of Windows: • The default value for an interface is always alternate setting zero. • Additional alternate setting numbers must be consecutive and increasing.

For additional information on alternate settings, see Section 9.6.5 of the. What are the major restrictions imposed by Usbccgp.sys? Usbccgp.sys supports composite devices for: • Windows Me • Windows XP • Windows Server 2003 • Windows Vista • Windows Server 2008 Although it might still be possible to load Usbhub.sys as the parent driver for the composite device on these and later versions of Windows, Microsoft does not recommend it because it might cause hardware compatibility errors.

You should use Usbccgp.sys instead. To ensure that you load the correct driver for your composite device, use the Include and Needs directives in your INF files, as follows.

• Usbccgp supports the interface association descriptor (IAD) only in Windows XP SP2, Windows Server 2003 SP1, and later versions of Windows. • Usbccgp supports nonconsecutive interface numbers only in Windows XP SP2, Windows Server 2003 SP1, and later versions of Windows. How do I enable debug tracing for USB core binaries? See the blog post about. For additional information about USB core stack debugging, see. Does Windows support Interface Association Descriptors? The USB 2.0 Interface Association Descriptor (IAD) Engineering Change Notification (ECN) introduced a new standard method for describing a grouping of interfaces and their alternate settings within a function.

IAD can be used to identify two or more consecutive interfaces and alternate settings within one function. Microsoft is currently working with IHVs to develop devices that support IAD. The following operating systems have support for IAD: • Windows XP Service Pack 2 and later • Windows Server 2003 Service Pack 1 and later • Windows Vista Does the USB stack handle chained MDLs in a URB? This functionality is supported by the USB 3.0 driver stack that is included with Windows. Can a driver have more than one URB in an IRP? This functionality is not supported by the USB stack that is included with Windows.

Does Windows Support USB Composite Hubs? A composite USB device - also referred to as a multifunction USB device - exposes multiple functions, each of which can be treated as an independent device. The system loads the USB generic parent driver, Usbccgp.sys, to serve as the parent driver for eaech of the device's functions. The USB generic parent driver enumerates the composite device's functions as though they were separate USB devices and then creates a PDO and constructs a device stack for each function. A composite USB device cannot expose a function that serves as a hub. Windows does not enumerate such hubs properly and attempting to install the device might cause a system crash.
