![]() ![]() See my question "Enable USB-OEM (HID POS) mode in a Datalogic barcode scanner" for details on that.īut if you don't want to go down this route of writing your own USB handlers, you can always just get a common Serial-to-USB adapter and install a matching serial driver on your Mac, and then use the scanner in serial mode. ![]() With some reverse engineering and digging I figured out that protocol as well, though. Instead, they use a private protocol that's not publically documented. However, some scanners, like those made by Datalogic, do not use the official HID protocol for scanners. But I found it not too difficult to accomplish. You'll have to implement some USB specific code in your OS X app for this, using the IOKit API for user space handling. The USB HID specificaton does define the codes for barcode scanners, and some scanners, like the ones made by GoDEX, follow this protocol. In that mode, the scanner remains connected to the computer directly via USB but it won't send keyboard presses any more but rather codes similar to what you get with the serial port mode. The modern approach to your problem is to configure the barcode scanner to use the so-called HID POS or USB OEM mode. ![]()
