Hi ALL!

I want to use a barcode scanner on FreeBSD. I have USB Honeywell MS9520.

After attach in log:
Code: 
ugen0.4: <Honeywell Scanning and Mobility> at usbus0
ukbd1: <Honeywell Scanning and Mobility Honeywell Scanning and Mobility Scanner, class 0/0, rev 1.10/58.81, addr 4> on usbus0
kbd3 at ukbd1
ugen0.4: <Honeywell Scanning and Mobility> at usbus0 (disconnected)
ukbd1: at uhub0, port 6, addr 4 (disconnected)
ugen0.4: <Honeywell Scanning and Mobility> at usbus0
The first question is: why is first defined as a keyboard, and then ugen? The second question: the device is, how to get information from it?

I understand that this device can be seen as a reference system keyboard, but just do not know how to get information from him.

Finished programs not in the ports tree.
 
Have you tried scanning a barcode? You might find it just inputs characters as if you had typed them at a keyboard.
 
That's the way most scanners work. They just type the characters the same as if the user had entered them. That's also the reason there is usually a human-readable version of the barcode information below it: so it can be manually entered if the barcode is damaged.
 
I understand how a bar code scanner work.
But both see and touch and save the result of his work?

See the dump, log, etc.

How to see the results? How?
 
Ok.
What to see this INPUT?

Need a sniffer to see this input information.
usbdump fit?
Or are there other applications of this type?
 
Can't you just open a text editor, scan a barcode and see if the code text gets "pasted" to the editor? Am I missing something obvious here?
 
Any USB barcode scanner should be just another USB keyboard to FreeBSD (and other operating systems). Can you post the outputs of

# usbconfig

And
# dmesg | grep ukbd
 
Hi all!

I start my post with log message:

Code: 
1. Nov 30 11:04:03 irc-ws17 kernel: ugen0.4: <Honeywell Scanning and Mobility> at usbus0
2. Nov 30 11:04:03 irc-ws17 kernel: ukbd1: <Honeywell Scanning and Mobility Honeywell Scanning and Mobility Scanner, class 0/0, rev 1.10/58.81, addr 4> on usbus0
3. Nov 30 11:04:03 irc-ws17 kernel: kbd3 at ukbd1
4. Nov 30 11:04:03 irc-ws17 kernel: ugen0.4: <Honeywell Scanning and Mobility> at usbus0 (disconnected)
5. Nov 30 11:04:03 irc-ws17 kernel: ukbd1: at uhub0, port 6, addr 4 (disconnected)
6. Nov 30 11:04:08 irc-ws17 root: Unknown USB device: vendor 0x0c2e product 0x0720 bus uhub0
7. Nov 30 11:04:08 irc-ws17 kernel: ugen0.4: <Honeywell Scanning and Mobility> at usbus0

From this came the questions:
Why is first defined as a keyboard, and then ugen?

The Trace log:
Code: 
Point 1: Insert Scanner
Point 2: Detect Scanner As Keyboard
Point 3: Apply Driver ukbd
Point 4, 5: disconnected - (WHY?)
Point 6: Unknown USB device
Point 7: Scanner Now ugen

That is, the scanner was an unknown device and not the keyboard.
As it is now possible to handle events like keyboard scanner?

Therefore, usbdump and xev shows nothing.

What is there in Notepad text processing?
 
Little understood.
I work with USB keyboard: console and X
USB Scanner is TWO USB keyboard.

My Device NOT work as keyboard.
An attempt to append the device through kbdmuh produced an error by kbdcontrol:

kbdcontrol: unable to obtain keyboard information: Inappropriate ioctl for device
