So I have a QNX 6.1.0 sdk and I am been using QNX 6.3.0 Momentics IDE to build 6.1.0 .ifs images. I would like to know 
if it is possible to access the USB device after booting from it with 6.1.0 .ifs image.

As far as I can tell I didn't see any devb-umass drivers or io-usb utility inside the 6.1.0 sdk. All I see anything 
related to usb is devu-uhci and devu-ohci drivers and a utility called usb which does not do much except displaying USB 
device config info (as per manual page).

So basically my question is it is possible to access/mount USB devices in 6.1.0 version of QNX? Based on my research and
 understanding I think it is not possible because of lack of proper USB drivers and USB stack and therefore you cannot 
do something like this in your build file:

<snip>
# Start USB
	io-usb -duhci -dohci -dehci
	waitfor /dev/io-usb

	devb-umass disk name=umass
	waitfor /dev/umass0t79
	mount -t qnx4 /dev/umass0t79 /
        waitfor /sbin
<snip>

Just wanted to ask here to see if I am missing something...

Thanks
