My Device HP 4430 2D Imaging Barcode Scanner not listing

[IlmadEddine]

I tried pure javahedabe api to read data from my device but I could not find it in list of devices attached

I loved it because the others APIs doesn't have input Listener

any idea for resolve this

Barcode Scanners can be programmed to operate in different modes. There's usually a booklet with a bunch of barcodes to switch modes. If you don't have the booklet you should be able to find a PDF online with the barcodes.

For example, if this barcode scanner is configured for RS232 communication, it will show up as a COM/Serial port on your computer.

Which platform you are using (Linux,Windows or Mac OS)? I'm mainly on Mac but I'm sure there is a system utility by which you can see how the device presents itself to the system i.e. is it COM or .tty or HID or whatever...

Windows x64
I can switch to COM / USB ... I'm sure it's a USB HID like keyboard

@IlmadEddine you will have to switch it off of Keyboard mode per: https://github.com/nyholku/purejavahidapi#why-hid

Most HID devices (like Mouse, Keyboard etc) have specific APIs provided by the operating system and you should use those to access them.

However some device which are not really Human Interface Devices in the original intent of the USB HID standard nevertheless represent themselves as HID devices. Devices like ThinkGeek USB Rocket Launcher or Oregon Scientific WMR100 weather stations to name two.

I try Hid4Java .. in console i have this

Device attached: HidServicesEvent{hidDevice=HidDevice [path=\?\hid#vid_03f0&pid_0139#7&2dbe7f3a&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}, vendorId=0x3f0, productId=0x139, serialNumber=S/N VNC2442289, releaseNumber=0x77, manufacturer=Hewlett-Packard, product=HP Image Scanner, usagePage=0x1, usage=0x6, interfaceNumber=-1]}

Device detached: HidServicesEvent{hidDevice=HidDevice [path=\?\hid#vid_03f0&pid_0139#7&2dbe7f3a&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}, vendorId=0x3f0, productId=0x139, serialNumber=S/N VNC2442289, releaseNumber=0x77, manufacturer=Hewlett-Packard, product=HP Image Scanner, usagePage=0x1, usage=0x6, interfaceNumber=-1]}

Next thing to do would be to step through or instrument the enumeration code to see what happens:

purejavahidapi/src/purejavahidapi/windows/WindowsBackend.java

Line 78 in 55fcca5

public List<purejavahidapi.HidDeviceInfo> enumerateDevices() {

I read this

Device USB\VID_03F0&PID_0139\S/N_VNC2442289 was not migrated due to partial or ambiguous match.

Last Device Instance Id: USB\VID_0461&PID_0010&MI_00\7&30821C4&0&0000

witch part i should add to InterfaceClassGuid List ?

i don't understand your code but i show some message
inside enumerateDevices function :

These line in your example after call PureJavaHidApi.enumerateDevices() function :

Does this device work with any software in your system?

googling for " was not migrated due to partial or ambiguous match." suggest that this could be a driver issue...

[IlmadEddine]

As Standard output yes (must be text input editable) (I can switch to Serial Port ... No)

I can confirm this library works properly with HID barcode scanners. I've recently integrated with a Honeywell Scanner using PureJavaHIDAPI.

I ran into two caveats which may or may not be immediately beneficial to this thread:

• The drivers from the vendor were needed for proper operation
• The device exposed two matching VID/PID endpoints, I needed to use the Usage Page to distinguish the correct endpoint.

The HP scanner offers some drivers as well. If they don't install automatically you may need to browse to the driver location and install them manually. https://support.hp.com/us-en/drivers/selfservice/hp-imaging-barcode-scanner/5061524/model/5061525
