Detailed documentation at URL given above. (1) Calcomp DrawingBoard III digitizing tablet fails to initialize as xinput device at startup due to timeout error. From /var/log/Xorg.0.log: (WW) Timeout while reading Calcomp tablet. No tablet connected ??? (EE) Unable to query/initialize CALCOMP hardware. User fix in xf86Calcomp.c: At line 787, change "int retries = 5;" to "int retries = 100;" (2) After fixing (1), "xinput list TABLET" retrieves "7616" from the driver as the tablet axis 1 limit instead of the correct number, "24000". User found error (missing line of code) in xf86Calcomp.c. At line 608 change priv->max_y = (int)buffer[5] + ((int)buffer[4] << 7); to priv->max_y = (int)buffer[5] + ((int)buffer[4] << 7) + (((int)buffer[3]&0x03)<<14); (3) "xinput set-pointer TABLET" fails on calcomp tablet. X Error of failed request: BadDevice, invalid or uninitialized input device Major opcode of failed request: 146 (XInputExtension) Minor opcode of failed request: 12 (X_ChangePointerDevice) Serial number of failed request: 12 Current serial number in output stream: 12
