Installation procedure

To install the USB 2.0 drivers:

1. Log in as root.
2. Download the USB 2.0 driver archive (QNX4-USB-2.0-20051114.tgz).
3. Backup the existing USB drivers.

   ---

   If you wish to keep a copy of the existing drivers and utilities, you'll need to save them in a safe location first, to prevent them from being overwritten during installation. # cp -Rvc /bin/devu* /backupdir

   ---

4. Get the checksum to ensure that the binary is correct:

   # cksum QNX4-USB-2.0-20051114.tgz

5. Compare the result against the checksum posted on your myQNX account.
6. Extract the archive with the updated drivers:

   # cd /
   # gzip -d <download-path>/QNX4-USB-2.0-20051114.tgz 
   # tar -xvof <download-path>/QNX4-USB-2.0-20051114.tar

   The following driver will be installed:

   • /bin/devu-kbd
   • /bin/devu-mouse
   • /bin/devu-prn
   • /bin/io-usb
   • /bin/usb
   • /bin/Fsys.umass

7. Make sure that the binaries are executable:

     # chmod 775 /bin/devu* /bin/*usb* /bin/Fsys.umass
     # chown root:root /bin/devu* /bin/*usb* /bin/Fsys.umass
