o We have no PCI- and no SCSI-System, but all USB-drivers need CONFIG_PCI=y.
  USB-Floppy driver need the SCSI-Subsystem, so we must enable this global
  and disable all low level drivers in this menu.
--- OR ---
  Download origanal kerneltree, and patch comlplete ADNP
  with USB support and load configuration for this:
	bunzip2 -c linux-2.4.20.tar.bz2 | tar xvf -
	gunzip -c linux-2.4.20-SSV20030516.diff.gz | patch -p1 -T
	Configuration: arch/i386/adnp1486-usb104-SSV20030516
  
o Compile the kernel
  make dep
  make ROOT_DEV=/dev/ram0 zImage
  make modules
  export INSTALL_MOD_PATH="`pwd`/_install" ; make modules_install


Default device configuration hc_sl811.o for USB1/104:
-----------------------------------------------------
io	= 0x220
irq	= 12
Remember: Second Controller was handled internal with IO offset +2.


Installation hc_sl811.o for CF1/USB:
------------------------------------
Compact Flash to USB adapter in io address of ide driver. It is for embedded
deviced only.
Please disable IDE driver in kernel configuration or do not load IDE drivers!
Change MAX_CONTROLERS = 1 into source asm/sl811-hw.h, recompile driver!
  First Controller only
    insmod hc_sl811.o io=0x1F0 irq=14
  Second Controller only
    insmod hc_sl811.o io=0x3F6 irq=14

Driver hc_sl811.o can not handle both controllers at same time.
This driver need a address-offset of 2 between controllers.
Please use alternate driver sl811.o instand.


Installation Alternate driver sl811.o:
--------------------------------------
This driver have a better interrupt handler, but don't tested with all devices.

Install both controllers on USB1-104 (default):
    insmod sl811.o io=0x220,0x222 irq=12,12

Install both controllers on CF/USB1:
    insmod sl811.o io=0x1f0,0x3f6 irq=14,14

Second controller can disable with specific IOBASE=0 for this controller.


General about USB:
------------------
Please install first the driver for hardware,
and than plugin the hardware into first USB port.

If your hardware find no driver the usbcore give ub a massage for missing
driver on conole or in file /proc/kmsg such as:
    new USB device <NULL>-1.9, assigned address 7
    USB device 7 (vend/prod 0x403/0x8372) is not claimed by any active drive
In this case remove the hardware from USB port, install the driver and
than plugin hardware again.
A list of driver for this missing hardware can found in file
/_install/lib/modules/2.4.20/modules.usbmap
Search the number 8372 in this file an verify the vendor ID. So you will
find the driver name "ftdi_sio" in this file.
If your hardware not listen in this file. Look into source and search your
numbers in source.
More read file:/Documentation/usb/proc_usb_info.txt

Drivers are all under contructions. So some drivers make a kernel panic. In
this case read all about the drivers dokumentaiona and the drivers source.
Some drivers need a other kernel driver, but not strictly checked in kenel
configuration. Here can help the ksymsoops.



Install a Floppy (NEC UF0001) or USB Stick Fujitsu/Siemens/iomega:
------------------------------
Copy files to target (FTP) and load all drivers.
Load Generic USB-Handler
	insmod usbcore.o
Load USB-Host controller, parameters are optional (default urb_debug=0 io=220 irq=12)
	insmod hc_sl811.o
Run the USB-Filesystem
	mount -t usbdevfs usbdevfs /proc/bus/usb
Load drivers for disk storage and file systems
	insmod scsi_mod.o
	insmod usb-storage.o
	insmod fat.o
	insmod vfat.o
	insmod sd_mod.o
Create node for floppy
	mknod /dev/sda b 8 0

Put a disk into your floppy anth than plugin a USB-Floppy (such NEC Model UF0001)
into first USB-Port. Some Messages will be list on console or in file /proc/kmsg.
The disk is power on and the SCSI driver will search some partions on disk. Floppy
have no partions, so must use the first SCSI device without a partion number for mount.
Than mount the floppy:
	mount /dev/sda /mnt -t vfat

If you see a partions check with valid partion 1, you should mount this partion.
Mostly Memory Sticks are formated with one partion. But if Windows format it again,
no partions is use.

You see that:
	Partition check:
	 sda: sda1
Than mount with follow steps:
	mknod /dev/sda1 b 8 1
	mount /dev/sda1 /mnt -t vfat

Create complete list of nodes for SCSI-devices:
    # First inserted device
    echo -n "Create /dev/sda... "
    mknod /dev/sda b 8 0
    for i in  1 2 3 4 5 6 7
    do
      echo -n "$i "
      mknod sda$i c 8 $i
    done
    # Second inserted device
    echo -n "Create /dev/sdb... "
    mknod /dev/sdb b 8 16
    mknod /dev/sdb1 b 8 17
    echo " done"
    # Set some rights
    chown root.disk sd*
    chmod 660 sd*


Install a Keyboard:
-------------------
Copy files to target (FTP) and load all drivers.
Load Generic USB-Handler
	insmod usbcore.o
Load USB-Host controller, parameters are optional (default urb_debug=0 io=220 irq=12)
	insmod hc_sl811.o
Run the USB-Filesystem
	mount -t usbdevfs usbdevfs /proc/bus/usb
Load drivers for USB-Keyboard
	insmod input.o
	insmod keybdev.o
	insmod usbkbd.o
Now you can plugin Keyboard into first USB-Port and login on first console.

Something stuff:
"Undefined Symbols handle_scancode, keyboard_tasklet, kbd_ledfunc" at install ???
USB keyboard need PC-style keyboard driver, because the USB driver
simulate standard AT-Keycodes. A normaly AT- or PS/2-Keyboard must not
exist for this. The driver says normaly error (Timeout) on boot.
You must enable CONFIG_VT in kernel konfiguration!
Character devices  --->
    [*] Virtual terminal
    [ ]   Support for console on virtual terminal

Read <file:Documentation/input/input.txt>


Install a Mouse:
----------------
Load Generic USB-Handle
	insmod usbcore.o
Load USB-Host controller
	insmod hc_sl811.o
Run the USB-Filesystem
	mount -t usbdevfs usbdevfs /proc/bus/usb
Load Generic Input device
	insmod input.o
Load USB-Mouse driver
	insmod input.o
	insmod mousedev.o
	insmod usbmouse.o

Read <file:Documentation/input/input.txt>


Install a serial adapter (Sample FTDI):
---------------------------------------
Load Generic USB-Handle
	insmod usbcore.o
Load USB-Host controller
	insmod hc_sl811.o
Run the USB-Filesystem
	mount -t usbdevfs usbdevfs /proc/bus/usb
Load Generic derial device and hardware specific device
	insmod usbserial.o
	insmod ftdi_sio.o
Create node entry for this device
	mknod /dev/ttyUSB0 c 188 0
Than plugin the hardware into first USB port and
use serial device on /dev/ttyUSB0, such call a login:
	/sbin/getty 115200 ttyUSB0 vt100 &


USB-Utils:
----------
- usb-0.6-7.rpm, usb-0.6-7.src.rpm
  /usr/sbin/lsusb, /usr/share/usb.ids
  Good tool to list devices parameters.
  You must load usbcore.o, hc_sl811.o and proc-usb before
  program works right (use script usb.sh).
  More details: Install usb-0.6-7.rpm on Your desktop and use "man lsusb".


Known Bugs:
-----------

PL2302 Profilic USB to serial converter will not work with hc_sl811.c (Bulk/Timeout).
USB Floppy will not work with alternate driver sl811.o (Sector not found)

* 18.11.2002 hne
- hc_sl811_rh.c:
  rh_unlink_urb: Use usb_dec_dev_use instand of usb_put_dev. Function
  usb_put_dev isn't known in this module. Some others have a macro for
  this. What is right usb_put_dev or usb_dec_dev_use?
- hc_sl811.c:
  Split into 3 files. Arcitectures store in hc_sl811-arm.c and hc_sl811-x86.c
  Correct release_region() for both io address, so we can unload modul and
  load again without reboot.
  All IO access use 8 bit Data and register number (type __u8).
  All functions static.
  Only x86: base_addr renamed to io. data_reg_addr not used.

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
