USB Basic Device Driver Support

USB drivers update for OS/2 v12.03 In this release =============== This release is intended to update an existing installation. The installer will not install or change host controller drivers but it can install certain class drivers. This release contains the following files: The Host Controller drivers and USB driver: - USBEHCD.SYS (USB 2.0 EHCI hardware driver) - USBOHCD.SYS (USB 1.x OHCI hardware driver) - USBUHCD.SYS (USB 1.x UHCI hardware driver) - USBD.SYS (USB driver) The Human Interface class drivers - USBHID.SYS (Human Interface driver) - USBKBD.SYS (USB Keyboard driver) - USBMOUSE.SYS (USB Mouse driver) Some other class drivers: - USBCOM.SYS (USB COM port and modem driver) - USBPRT.SYS (USB printer driver) - USBAUDIO.SYS (USB Audio driver)(16 bit) Other files: - USBRESMG.SYS (USBCALLS driver) - USBCALLS.DLL (USBCALLS DLL) - USBCALLS development sample code Copyrights and Licensing ======================== Copyright (c) 2011-2019 David Azarewicz <david@88watts.net> All rights reserved.

Portions of the code may also contain modifications from the contributors to this code such as Lars Erdmann, Wim Brul, and others, to whom we are very grateful for their work.

By downloading or using this software, you acknowledge that you have read and consent to the license agreement contained in the separate License.txt file, that you understand it, and that you agree to be bound by its terms. Installation ============ The distribution is a self executing WarpIn package. Simply run it. This release is intended to update an existing installation only. The installer will not check for which host controllers you have in your system and it will not change the host controller drivers in your config.sys. The installer will only update the USBAUDIO driver if it is already installed. The installer will only update the USBXHCD driver if it is already installed and you have XHCI hardware in your system. On the Packages page, make sure you select and/or deselect the drivers you want and/or don't want to update. Many driver are a matched set and cannot be updated individually. For this reason matched drivers are grouped into packages and cannot be selected individually. USBRESMG.SYS and USBCALLS.DLL are a matched set and must be the same version. There are many different old versions of USBRESMG.SYS and USBCALLS.DLL distributed with various other packages. If you are having problems with the USBCALLS interface, make sure that you are not using mismatched versions. Beware of other versions of USBCALLS.DLL in your LIBPATH or current directory. Note that from version 11.01, the usbcalls library was reorganized to try to merge the functionality from all the different versions and create a universal interface. A few versions were incompatible and those incompatible interfaces were discarded in favor of the more capable, more popular modern ones. If your application is very old or was linked with an incompatible library, you will need to relink your application with the new library. The version 12.x drivers require USBD.SYS to load before the HC drivers in CONFIG.SYS. This is different than the old 11.x drivers. The Warpin installer changes the CONFIG.SYS if necessary. Getting Support and Reporting Problems ====================================== For more information and to report problems please visit: https://www.arcanoae.com and click on SUPPORT. Or go directly to the USB support wiki at: https://www.arcanoae.com/wiki/usb/ Requirements, Limitations, and Known Problems ============================================= If a device is plugged into a root hub and powers up in an inoperative state, or if the BIOS puts the device into an inoperative state, the device will not work until it is repowered (ie. plugged in after bootup). This applies to any type of device, but especially hubs and KVM switches when a non-compliant device is plugged into them. This is a hardware limitation, not a driver defect. This problem exists on all other platforms as well. The OS/2 USB audio driver in this release is developed to support any USB audio device that follows USB Audio device class 1 specifications. To use this driver you must have the following prerequisites: 1. A USB audio device that conforms to the class 1 specification. 2. Basic USB support must be installed (HC driver, USBD). 3. Multimedia services must be installed. 4. The USBAUDIO driver must have already been installed in order to be updated by this release.
