Description Robert Penny 2007-12-28 21:42:18 UTC 
Most recent kernel where this bug did not occur:
Distribution:

Noticed in linux-2.6.23-gentoo-r3, but the latest mainline kernel linux-2.6.23.12 is no better.

Software Environment:
Problem Description:

Although it seems that support for Wacom digitizing tablets has been folded in to the mainline 2.6.23 kernel source tree, the code is old in comparison to the Linux Wacom Project code SourceForge repository code for earlier kernels.

My specific problem is that the "Bamboo Fun" tablet, with a prodID = 0x17 is not supported in the mainline 2.6.23 kernel code.

from linux-2.6.23.12/drivers/input/tablet/wacom_wac.c:

static struct usb_device_id wacom_ids[] = {
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x00) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x10) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x11) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x12) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x13) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x14) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x15) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x16) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x60) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x61) },
        { USB_DEVICE(USB_VENDOR_ID_WACOM, 0x62) },

From the Linux Wacom SourceForge repository, the latest update to wacom_wac.c was for 2.6.19 which has code:


  657 static struct usb_device_id wacom_ids[] 
  658 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x00) },
  659 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x10) },
  660 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x11) },
  661 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x12) },
  662 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x13) },
  663 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x14) },
  664 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x15) },
  665 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x16) },
  666 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x17) },
  667 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x18) },
  668 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x60) },
  669 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x61) },
  670 	{ USB_DEVICE(USB_VENDOR_ID_WACOM, 0x62) },

My apologies if I'm wrongly assuming this counts as a bug that I should be reporting to kernel.org.

Thanks,

-Rob.

Robert,

I rely on Wacom driver maintainer to feed me the patches when she decides that they are tested enough for mainline. Please try askign on linux-wacom lists/forums and see if she plans an update.

Thanks.
