In order to manually update your driver, follow the steps below (the next steps):ġ.

Take into consideration that is not recommended to install the driver on Operating Systems other than stated ones.

If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version. On the plus side, this is probably not the hardest possible driver project to get started on.The package provides the installation files for ELAN PS/2 Port Input Device Driver version 15.7.9.2. if you aren't already intimately familiar with those topics. Expect to read up on USB, HID, the xnu kernel, kext development, etc. An example of a driver that modifies HID report descriptors (but not reports) for OSX to make sense of them is here: ĭepending on your level of experience with this kind of thing, there's probably quite a bit in there that doesn't make a whole lot of sense initially. The other useful technique is to trace through the IOHIDFamily soirce to find out where it's going wrong. Apple's own trackpad) and try to turn your device's into a similar form. The best way is probably to look at the report descriptor for a similar device (e.g. You'll need to either modify the report descriptor, or both the descriptor and every report to something that makes sense to OSX.

If your device already shows up as HID, then either OSX isn't interpreting the report descriptor as a pointing defice correctly, or it can't make sense of the resulting reports. Once you have HID descriptors, the question is whether OSX can interpret them as is.

Check the IOHIDFamily source for details, and use a mouse or so as a working reference. You need to publish it to the OS as a HID device. Once you have worked out the messages, you may need to translate them into HID reports, together with a report descriptor that tells the OS how they're formatted. Then painstakingly work out what it all means. Easiest way is to install Windows in a VM, pass the USB device through to the VM, load the driver there, and log all of the USB traffic on your host machine. If there's no OSS driver, reverse engineer the Windows one. I'd recommend trying to write a user space USB driver first, and porting it to the kernel when you're happy with the messages you're getting. Not straightforward, expect this to take you quite some time if it's your first driver. If there's an open source Linux or BSD driver, you can probably work it out from that source and translate it into an IOKit kext for OSX. If it doesn't report as a HID device, you'll need to figure out its hardware interface in detail. (Read up on USB device configurations if this doesn't ring a bell.) Note that its default configuration may not be the only one, and if there are multiple device configurations, the default one likely isn't the most fully featured one.

You'll likely find it attached to a USB bus, but a key question is what drivers are already matched on it. Easiest way to find out is to download the Hardware IO Tools from Apple's developer website, or the open source IOJones, and look for the device in the service tree. It's most likely a USB HID device, although if not, it's going to be more work, as you'll need to turn the messages the device sends into HID reports one way or another. Depends on what you already know/have experience with, and how much time and persistence you'd like to invest in it, and of course, the awkwardness of the hardware itself, as to whether it'll be worth it.ĭetermine type of hardware interface.
