The PrefPane version 2.0b20 reports 'No tablet found'. Winplot download for mac.

Mac OS X 10.10.2 does recognize the tablet's input as a mouse.

TabletMagic is pretty old-school. It only supports serial (RS232) tablets and not the later USB models. I'm not sure how well Wacom's driver works, but they claim it is supported for OS X 10.10.x.

Wacom has the bad habit of naming different generations or altogether architecturally different products the same.

The Bamboo Pen CTL-460 certainly does not work with their drivers in Yosemite and, at any rate, I was hoping to be able to also use my trusty Intuos (the very first USB Intuos, GD-0912, from around year 2000 I think), which no Wacom official drivers support in Yosemite either, so 'old-school' is a relative term (^_-).

Are there no plans to support USB models? Do you know of a similar unofficial project that does, considering the existence of the Linux Wacom Project?

Edit: My mistake. The Bamboo Pen CTL-460 does indeed work in Yosemite with Wacom latest drivers. I had in mind a Graphite 4 (I have several Wacoms lying around) instead, which does not. Edited the title accordingly.

@elmimmo Unfortunately this project is not aimed at USB devices, which require a Kernel Extension (KEXT). It's an old-school driver that just connects to a serial port and does all its work in user space. There may be an open source USB / tablet driver for OS X created by someone out there, and that would be a better place to start than TabletMagic. In fact almost any USB device driver would be a better place to start. USB drivers, Kernel Extensions, HID, etc., are unfortunately all outside of my expertise.
