Subject: [SERIAL] Claim Wacom tablet device on HP tc1100 tablet
Date: Fri, 11 Nov 2005 16:55:22 -0700 [thread overview]
Message-ID: <200511111655.22637.bjorn.helgaas@hp.com> (raw)
Claim the WACF005 device. This is the pen display pointing device on
the HP Compaq tc1100 Tablet PC. More information about using this
device, including using it as an X pointer device:
http://www.theory.bham.ac.uk/staff/schofield/linux/tc1100/
Christopher Kemp <ck231@cam.ac.uk> did the legwork of determining that
the WACF005 is really just a plain old UART and doing an initial ACPI
driver (before we had PNPACPI), and David Ludlow <dave@adsllc.com>
confirmed that PNPACPI + the attached patch is now sufficient:
pnp: Device 00:05 activated.
ttyS4 at I/O 0x300 (irq = 4) is a 16550A
