[Utopia] gnome volume manager not recognizing usb

["gowriganesh somasundaram" <gowriganesh gmail com>]

members,

i'm creating a live cd for my linux distro based on debian of kernel
verion 2.6.12smp. i'd created my installable cd with udev, hal, pmount
and latest gvm. when i insert usb i could find my icon for usb
instantaneously. but when i created livecd i could not see the icon
corresponding to the  usb, but the nautalis recognizes and opens
the file browser window which shows the fle contents in the usb(this
happens bcos i'd made changes in the FHS of policy.h of pmount). The
livecd is based on the concept of the knoppix where the contents will
be loaded in the /UNIONFS/ folder on mount. 

Following is the snapshot of 

1. dmesg

3. mtab output

Though FHS has to be followed i'd added /UNIONFS/ string prefixed to
the directory structure provided in the policy.h of the pmount and made
the usb to mount. 

my problem is i like to know why gvm is not recognizing the usb and displaying the icon on the desktop.

Thanks in advance.
