10 You've found a document detailing how to match up the kernel side driver
11 part (wacom) with the userspace configuration for the tablet.
12
13 The problem in this case is that the kernel driver is not recognizing
14 the device, and hence is not creating the /dev/input/eventX interface
15 that the document is talking about. So, the document is not entirely
16 relevant because the problem occurs at a lower layer.
17
18 The next thing to do on that bug is to research the issue. Try and find
19 other Linux users who have the same hardware, and see whether they are
20 reporting it as working or broken. If it appears broken for everyone,
21 has it been reported to the wacom developers, perhaps on a mailing list?
22 Are there any patches available? Google around a bit, and let us know
23 what you find (if you're confident you can just put your findings
24 directly on the bug).
25
26 Also, you'll see that I asked for "lsusb -v" output. I asked for this
27 because all USB devices have unique ID numbers (vendor and product ID)
28 which can be useful when searching. In this case the vendor ID is 056a
29 and the product ID is 0090 (see if you can find where I read those
30 numbers from in his attachment).
31 Just putting the phrase "056a 0090" into google seems to bring up some
32 relevant results.

34 Thanks,
35 Daniel
