USB & Fsys.umass problem getting access to device under 4.25   
Trying to get USB memory stick to work.
Using QNX 4.25 with USB 2.0 package installed.
Using Ampro motherboard (82801 DBM I/O hub) with both USB v2.0 EHCI and UHCI v1.1.
Using
   #io-usb
I get the 'usb' entry under /dev (this is the stack/driver?)
Using 
   #usb
I can see either a full speed USB memory stick under the UHCI interface, or a high speed under the EHCI interface. 
Then trying the 
   #Fsys.umass
it seems to recognize the device and there are no errors, but no new device like 'usb0' shows up.
Is there a trick to this final step to get the device available?

Process list seems fine (have io-usb and Fsys.umass).
I have tried numerous combinations, but nothing changes.  Always get the usb stack, but nothing more.

Re: USB & Fsys.umass problem getting access to device under 4.25   
Using the syntax:
   Fsys.umass fsys -l -n Direct-Access=usb
I can get a usb0 to show up in /dev.

However, I can seem to do anything with it.  A mount like:
   mount /dev/usb0 /fs/usb
justs hangs.
The USB memory stick's light is on.

Had lots of issues with this stuff as well

try Fsys.umass......
sleep 2
mount -p /dev/usb0
sleep 3
mount -t dos /dev/usb0t12 /dos/e

This assumes that your USB has partitions

Please post the output from 'show_pci -v' so that we can see what USB
adapters you have.

I have also this problom.
run "shoe_pci -v", get:
......

Device ID = 7112h, 
PCI index = 0h 
Class Code = 0c0300h Serial Bus (Universal Serial Bus) ProgIF=0 
Revision ID = 0h 
Bus number = 0 
Device number = 7 
Function num = 2 
Status Reg = 280h 
Command Reg = 5h 
Header type = 0h Single-function 
BIST = 0h Build-in-self-test not supported

Subsystem ID = 1976h 
Max Lat = 0ns 
Min Gnt = 0ns 
PCI Int Pin = 4 
PCI Int Pin = INT D 
Interrupt line = 9 
......

what can I do for this?
Thank you!

Hi wang,

Do you use the latest version from the QNX4 Project?

Re: USB & Fsys.umass problem getting access to device under 4.25   
I had lots of trouble with this. Here is a script I have devised to open different USB sticks. I have several sticks 
with specific items on them. Each manufacturer seems to have a different device name.

  use vedit and put this into a file I call it "loadusb" then put it in the /usr/local/bin directory. Use chmod +x to 
make it executable. 



#! /bin/ksh

# Use this file to mount a usb memory stick may be run using ./memstick then
# finishing command manually depending on the type partition on the device
io-usb &
Fsys.umass -v fsys -Nusb -nusb0. & 
mount -p /dev/usb0.0             	 # check /dev/to see partiton type
sleep 2

slay -fQ Dosfsys                     	 # needed before running Fatfsys.
slay -fQ Fatfsys                     	 # needed if Fatfsys is running from sysinit.

Fatfsys e=`ls /dev/usb0.0t*` 

sleep 1

echo ""

echo "    USB device loaded as /dos/e"
 
echo ""



 Use this script to unmount it so if you want to install another disk you can do it without rebooting; Make sure you put
 it in the same directory as above and make it executable.

#! /bin/sh

# makes it safe to remove a usb stick and allows reinstall without reboot
sync
umount /dos/e
umount /dev/usb0.0
rm /dev/usb0.0
slay -f io-usb
sleep 2
echo ""
echo "    Safe to remove USB device"
echo ""


I can post a tar file with both files later if you need them
