hi,
I have a usb barcode scanner that acts like a keyboard. It easily scans barcodes and if sth like notepad is open, it writes the result like a keyboard.
I want to use it in my financial application that is written in C++. I searched and saw many websites but couldn't find a simple result.
FYI:
1.the barcode scanner just acts like a keyboard, it has no feature to have a virtual com port or sth like that
2.the manufacturer doesn't have any API or SDK to work with it
3.I've tested libusb , usb-hid libraries, raw input, direct input from directx and ... but no success

It seems to be so easy but it's so hard. can you help me the simplest way to read the data from it?

Solution 1

Yeah, use it as a keyboard. All scanners can be programmed to send out a "end-of-scan" key combination. You would use that to determine when the scan has occurred.

Read the docs for your scanner and you should see how to do this.

Solution 2

libusb can work directly with USB HID device. Replace windows HID driver with libusb driver (inf wizard) and work with it directly (receive key buffers).
