usbconfig for fstab

[bashrules]

Hi all,

On my FreeBSD 9.0 PC, I have issues with external USB drives. Just figured out, I need to execute a command after plugging one in (and before mounting it):

# usbconfig -d ugen3.2 add_quirk UQ_OPEN_CLEARSTALL


Several questions:

- What does ugen3.2 mean? Can I blindly type this every time, or does this number change, say in the order of attaching USB devices or depending on the USB port?

- The drive is supposed to be mounted in fstab. What is the FreeBSD way of automatically executing the above usbconfig command in conjunction with fstab?

NAME
     ugen - USB generic device support

SYNOPSIS
     ugen* at uhub?

DESCRIPTION
     The ugen driver provides support for all USB devices that do not have a
     special driver.  It supports access to all parts of the device, but not
     in a way that is as convenient as a special purpose driver.

     There can be up to 127 USB devices connected to a USB bus.  Each USB
     device can have up to 16 endpoints.

Yesterday I installed FreeBSD 9.1 on an USB stick:

# dmesg |grep ugenugen0.1: <Intel> at usbus0
ugen1.1: <Intel> at usbus1
ugen0.2: <vendor 0x8087> at usbus0
ugen1.2: <vendor 0x8087> at usbus1
ugen1.3: <ServerEngines> at usbus1
ugen1.4: <Kingston> at usbus1

The ugen1.4 is my Kingston USB stick with the FreeBSD install.
If I plug in another USB stick I see the following:

# tail -f /var/log/messages

This one uses both 1.5 and 1.6

 # usbconfig -d 1.5 dump_info
ugen1.5: <USB Embedded Hub Prolific Technology Inc.> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE

# usbconfig -d 1.6 dump_info
ugen1.6: <USB Mass Storage Device Prolific Technology Inc.> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON

If I add a Sony USB stick at the back

Jan  4 05:45:58 usb-8g kernel: ugen0.3: <Sony> at usbus0

Jan  4 05:45:58 usb-8g kernel: da2: 1920MB (3932160 512 byte sectors: 255H 63S/T 244C)

So you can conclude that it is not safe to assume that these numbers are fixed. They depend on the USB slot.

It looks like you have to write a "/etc/rc.d" script for automatically mounting that device. An easier method would be a cron job which runs at "@reboot" time.

I don't know whether an interactive script would be acceptable .

Here is a beginning:

#!/bin/sh

# --- interactive script to run 'usbconfig add_quirk' before mounting

ID=""

# --- command 
#CMD="usbconfig -d $ID add_quirk UQ_OPEN_CLEARSTALL
CMD='usbconfig -d $ID dump_info'

# --- show all USB devices
echo USB devices ----
usbconfig

# prompt for unit and address
printf "\n\nPlease enter ugen nr: "
read ID

if [ ! "x$ID" == "x" ] ; then
   eval $CMD
else
  printf "\nSorry no ugen nr entered!"
  exit 1
fi

echo USB da* devices ----------
ls -l /dev/da*

echo camcontrol device list ---------
camcontrol devlist 

# --- for mount command
TYPE=msdosfs
OPTION=ro
MNT=/mnt
DEVICE=/dev/da2
SLICE=s1

echo mount -o ${OPTION} -t ${TYPE} ${DEVICE}${SLICE} $MNT
# mount -o ${OPTION} -t ${TYPE} ${DEVICE}${SLICE} $MNT

The output when running:

# ./usb_quirk_mnt

Please note that I temporarily used "dump_info" command instead of "add_quirk" and that the mount command is only being displayed and not executed.

Thank you for your script. I use it as a starting point.
