I am trying to put usb touchscreen into operation under QNX4

Device Address             : 1
Vendor                     : 0x04e7 (EloTouchSystems,Inc)
Product                    : 0x0050 (Elo TouchSystems 2216 AccuTouch® USB Touch
monitor Interface)
Class                      : 0x00 (Independant per interface)
 
I tried even to write own driver, but the only USB DDK I have found is beta version from 2001 010207.usb_sdk.tar.F and 
the only io-usb  I found is from package QNX4-USB-2.0-20051114.tgz with support of USB disks (Fsys.umass). When I try to
 call usbd_connect() I have got return value 275 EPROGMISMATCH (Program version wrong). Have I missed something or do I 
need to buy a product? or what ? (QNX version is 4.25)
