support for three types of host controller interfaces:


  Open Host Controller Interface (OHCI)

  Universal Host Controller Interface (UHCI).

  Enhanced Host Controller Interface (EHCI).


This package is a prerequisite for all the other USB packages.

2.0  USB-Basic Support

______________________


2.1  Installation Instructions

==============================


2.1.1  To use the USB driver files, you must first expand the USBBASIC.EXE package

       file into its (7) component files by performing the following:

       (a.) opening an OS/2 window 

       (b.) changing to the directory where USBBASIC.EXE is stored

       (c.) type USBBASIC at the OS/2 command prompt (this will extract the files).


       Continue with the USB Installation Instructions.


2.1.2  Execute the Host Controller Utility (HCIMONIT.EXE).

       It reports the number of UHCI, OHCI and EHCI Host controllers

       contained on your system. If no UHCI, OHCI or EHCI

       Host controllers are reported, you do not need to continue

       with the install. If you do not have a USB Host controller,

       you will not have any USB capability.


At the OS/2 command prompt, type USBINST.

USBINST installs the USB drivers or refresh the USB support currently on your PC.


If installing on an IBM 365 system add the parameter /FS to the USBUHCD entry

in CONFIG.SYS (for parameter explanation see section 2.3).


This completes the USBBASIC installation procedure. You must REBOOT your system.

You can install any of the other additional USB device drivers

after you have REBOOTed the system.



2.2 Adding USB Basic support to the OS/2 Installation Disks or Utility Diskettes

================================================================================


The USB Basic Device Support package provides the host controller interface

support for USB. It is a prerequisite for all USB device support

and must be the first USB drivers added to the Installation diskettes or

Utility diskettes and allows use of any USB devices when booting.

Individual USB device support packages can then be added to the Installation or

Utility diskettes. (eg. USB Diskette, USB CDROM, USB Keyboard, USB Mouse, etc.)

Refer to the readme included in the individual USB device support package for

instructions on updating the diskettes. If there is insufficient disk space on

the boot diskettes for the additional USB drivers, then follow the procedure

in the README.TXT found in the root directory

of your OS/2 system on the procedure to make additional space on the boot diskettes.  

When removing existing files from the Installation or Utility diskettes, make sure 

you remove or comment out the corresponding statements from both the CONFIG.SYS file 

and the SNOOPER.LST (if it exists) file. As a general rule, driver updates/additions

to the installation or utility diskettes will require driver file replacement or

additions and changes to both the CONFIG.SYS file and the SNOOPER.LST file.


2.2.1 Modifying Diskette 1


First determine the number and type of USB host controllers contained on your system

by performing the following instructions from section 2.1.2.


Add the following sequence of statements

to the CONFIG.SYS file on the Diskette 1:


  SET SAVECONNECT=1

  SET COPYFROMFLOPPY=1

  BASEDEV=USBD.SYS /I13


  BASEDEV=USBUHCD.SYS (one copy of this statement for each UHCI controller reported by HCIMONIT utility)


  BASEDEV=USBOHCD.SYS (one copy of this statement for each OHCI controller reported by HCIMONIT utility)


  BASEDEV=USBEHCD.SYS (one copy of this statement for each EHCI controller reported by HCIMONIT utility)


  BASEDEV=USBHID.SYS


Copy the following USB Device Drivers files to the Diskette:


  USBD.SYS    ( USB Base Driver )

  USBUHCD.SYS ( USB UHCI Host Controller Driver) 

  USBOHCD.SYS ( USB OHCI Host Controller Driver ) 

  USBEHCD.SYS ( USB EHCI Host Controller Driver ) 

  USBHID.SYS  ( USB Human Interface Driver ) 



For Warp 4 and Warp 3 the IDEDASD package from the OS/2 DDPak also should be

applied if installing OS/2 on a hard drive larger than 8.4GB.


Note: After installation from the modified diskettes remove the parameter /I13 from

      the statement BASEDEV=USBD.SYS and rearrange the USB device driver statements

      in the following order:

         1. USB Host Controller Driver statements like 

            BASEDEV=USBUHCD.SYS, 

            BASEDEV=USBOHCD.SYS,

            BASEDEV=USBEHCD.SYS

         2. USB Base Driver statement 

            BASEDEV=USBD.SYS

         3. Any Other USB Driver statements



2.3 Additional Driver Parameters

================================


The following are additional parameter that you can use in CONFIG.SYS

for the USB Basic Drivers:


2.3.1 USBD driver parameters for BASEDEV=USBD.SYS


PARAMETER       FUNCTION


   /V           Verbose Mode, displays driver information during OS/2

                initialization.



   /I13          /I13 parameter could be used to delay USB host

                 overtaking by the USB driver stack until after other

                 device drivers finish required initialization operations.

                 It could be used to boot from the USB floppy drive.


                 /REQ parameter controls USBD driver initialization:

                 driver at initalization time checks for a listed host

                 controller and fail to load if no

                 listed driver is loaded. The USB stack

                 supports the following parameter settings:


  /REQ:USBUHCD$ USBD driver is loaded only if UHCI compliant host driver is loaded

  /REQ:USBOHCD$ USBD driver is loaded only if OHCI compliant host driver is loaded

  /REQ:USBEHCD$ USBD driver is loaded only if EHCI compliant host driver is loaded


  /REQ:USBUHCD$,USBOHCD$,USBEHCD$

                 USBD driver is loaded only if one of the OHCI/UHCI/EHCI compliant

                 host drivers is loaded. This most general form of parameter

                 and must be used in most cases. If you are using /REQ parameter

                 all statements "BASEDEV=USBUHCD.SYS", "BASEDEV=USBOHCD.SYS"

                 and "BASEDEV=USBEHCD.SYS" must be first in the sequence of

                 USB statements.


2.3.2 USBHID driver parameters for BASEDEV=USBHID.SYS


PARAMETER       FUNCTION


  /V            Verbose Mode, displays driver information

                during OS/2 initialization.


2.3.3 USBOHCD driver parameters for BASEDEV=USBOHCD.SYS


PARAMETER       FUNCTION


  /V            Verbose Mode, displays driver information during OS/2

                initialization.


  /FS           Forces the driver to stop the USB host during the OS/2 shutdown process.

                This parameter can be used to prevent POST (power on system

                test) failures on some hardware with a legacy keyboard.


2.3.4 USBUHCD driver parameters for BASEDEV=USBUHCD.SYS


PARAMETER       FUNCTION


  /V            Verbose Mode, displays driver information during OS/2

                initialization.


  /FS           Forces the driver to stop the USB host during the OS/2 shutdown process.

                This parameter can be used to prevent POST (power on system

                test) failures on some hardware with a legacy keyboard.


2.3.5 USBEHCD driver parameters for BASEDEV=USBEHCD.SYS


PARAMETER       FUNCTION


  /V            Verbose Mode, displays driver information during OS/2

                initialization.


  /FS           Forces the driver to stop the USB host during OS/2 shutdown process.

                This parameter can be used to prevent POST (power on system

                test) failures on some hardware with a legacy keyboard.



2.4  Un-Install Instructions

============================


Delete or remark out the following lines from CONFIG.SYS file starting with

   BASEDEV=USBD.SYS

   BASEDEV=USBHID.SYS

   BASEDEV=USBOHCD.SYS

   BASEDEV=USBEHCD.SYS

   BASEDEV=USBUHCD.SYS

and delete the following files from the \os2\boot directory:

   USBD.SYS

   USBHID.SYS

   USBOHCD.SYS

   USBUHCD.SYS

   USBEHCD.SYS


Safely shut down and then re-boot your system to have those changes take affect.



2.5 Recommendations when not using any USB devices

==================================================


If you are running OS/2 on an IBM ThinkPad or other notebook system and you

do not use any USB devices then you may want to "remark" out the USB device driver

statements in your CONFIG.SYS file. You can remark out a USB device driver by

preceding the line in config.sys with "rem " or "REM ". This action may lower

your notebook's system power requirements and may help to extend the battery's

operating life.
