USB drivers for OS/2

USB drivers update for ArcaOS and OS/2 In this release =============== This release is intended to update an existing installation. The installer will not install or change UHCI, OHCI, or EHCI host controller drivers but it can install XHCI and certain class drivers. This release contains the following files: The Host Controller drivers and USB driver: - USBXHCD.SYS (USB 3.x XHCI hardware 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: - USBMSD.ADD (USB Mass Storage Device driver) - USBCOM.SYS (USB COM port and modem driver) - USBPRT.SYS (USB printer driver) - USBAUDIO.SYS (USB Class 1 Audio driver) - USBMOS.OS2 (Moschip USB to Ethernet driver) Other files: - USBRESMG.SYS (USBCALLS driver) - USBCALLS.DLL (USBCALLS DLL) - USBCALLS development sample code Copyrights and Licensing ======================== Copyright (c) 2011-2022 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. Binary programs and documentation for the USB drivers are licensed to and distributed by Arca Noae, LLC. Important! 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. Except for XHCI, 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. If you are running ArcaOS, the installer will check for XHCI controllers and will modify your config.sys accordingly. The installer cannot install the XHCI driver on non-ArcaOS systems so you will not see the XHCI driver in the package list on those systems. The installer will only update the USBAUDIO driver if a version 11.x or 12.x driver is already installed. The USBAUDIO package will not be available if you have a version 10.x driver installed. The installer will not overwrite an existing version 10.x driver. On the Packages page, make sure you select and/or deselect the drivers you want and/or don't want to update. Many drivers 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. Starting with 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 about the USB drivers 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. WARNING: The OS/2 DASD/IFS architecture is not designed to handle aborted disk transfers well. DO NOT disconnect or remove a USB MSD while a transaction is active, or when an error recovery is in progress. Always wait until the I/O is finished. Failure to wait will result in lost data and/or traps. Be aware that if a cache is used, the disk I/O may be delayed. An eject or reboot should be safe provided that you wait until it finishes. USBAUDIO -------- 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. This driver will not work on class 2 audio devices. 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. USBXHCD ------- Current known limits and problems with USBXHCD.SYS: 1. Isochronous transfer support may not be fully tested due to the lack of compatible drivers and applications. You may experience reduced performance and/or additional problems on systems that are not fully up-to-date or are not in the standard Modern Hardware configuration. Specifically, make sure you are are using the latest Arca Noae 14.203 SMP kernel, the latest ACPI PSD, and that you are *not* using the /VW switch for the PSD. Some old vintage devices may not respond correctly to standard USB protocols. The USB3 spec and consequently XHCI hardware enforces strict compliance with the USB standards. If you have one of these non-compliant devices, please let us know and we will investigate if a workaround is possible. Some older USB class drivers may not be entirely USB3 compliant, or may have defects that were tolerated with the old USB2 stack. These drivers will need to be updated before they will work with the Arca Noae USB3 stack. The USB stack will block access to XHCI connected devices for drivers which are known to be XHCI unsafe.
