The USB PFS devices could not able to mount in the Intel tar

[g_hari79]

When I insert philips PFS USB device, I am getting below error
io-fs-media(pfs): Unable to load iofs-pfs.so module (Unresolved symbols).

When I execute below command to mount pfs device, I am getting the error below is log for it.

QNX version = 6.4.0

I'm going to take a wild guess that the driver is written for a version 6.3 or less and needs to be recompiled under 6.4.

Thanks Maschoen for your quick response.

the versions of the libraries are as below.
# use -i /lib/iofs-pfs.so
NAME=iofs-pfs.so
DESCRIPTION=Play for Sure Library
DATE=2009/05/19-02:46:42-WEDT
STATE=Experimental
GCC_VERSION=4.2.4
QNX_VERSION=640

# use -i /lib/libusbdi.so.2
NAME=libusbdi.so
DESCRIPTION=Generic USBDI library
DATE=2009/05/20-16:40:42-EDT
STATE=stable
VERSION=6.4.1
TAGID=166

# ldd /lib/iofs-pfs.so
/lib/iofs-pfs.so:
iofs-pfs.so => /lib/iofs-pfs.so (0xb8200000)
My assumption is "libusbdi.so.2" library dependency is missing to iofs-pfs.so, correct me if I am wrong.

Please let me know if details are insufficient. Could you please help me out?
