The descriptor does not contain the ContactID usage and as result the touchscreen is represented as normal mouse to the system. This driver maps the button 0 emitted by the touchscreen to BTN_TOUCH. This makes it possible to use touch events in userspace. changes from v1 to v2 - incorporated feedback from Benjamin Tissoires Signed-off-by: Christian Gmeiner --- drivers/hid/Kconfig | 6 ++++++ drivers/hid/Makefile | 1 + drivers/hid/hid-penmount.c | 51 ++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 58 insertions(+) create mode 100644 drivers/hid/hid-penmount.c diff --git a/drivers/hid/Kconfig b/drivers/hid/Kconfig index c18d5d7..0351b66 100644 --- a/drivers/hid/Kconfig +++ b/drivers/hid/Kconfig @@ -530,6 +530,12 @@ config PANTHERLORD_FF Say Y here if you have a PantherLord/GreenAsia based game controller or adapter and want to enable force feedback support for it. +config HID_PENMOUNT + tristate "Penmount touch device" + depends on USB_HID + ---help--- + Say Y here if you have a Penmount based touch controller. + config HID_PETALYNX tristate "Petalynx Maxter remote control" depends on HID diff --git a/drivers/hid/Makefile b/drivers/hid/Makefile index 4dbac7f..e2850d8 100644 --- a/drivers/hid/Makefile +++ b/drivers/hid/Makefile @@ -71,6 +71,7 @@ obj-$(CONFIG_HID_NTRIG) += hid-ntrig.o obj-$(CONFIG_HID_ORTEK) += hid-ortek.o obj-$(CONFIG_HID_PRODIKEYS) += hid-prodikeys.o obj-$(CONFIG_HID_PANTHERLORD) += hid-pl.o +obj-$(CONFIG_HID_PENMOUNT) += hid-penmount.o obj-$(CONFIG_HID_PETALYNX) += hid-petalynx.o obj-$(CONFIG_HID_PICOLCD) += hid-picolcd.o hid-picolcd-y += hid-picolcd_core.o diff --git a/drivers/hid/hid-penmount.c b/drivers/hid/hid-penmount.c new file mode 100644 index 0000000..02de4b8 --- /dev/null +++ b/drivers/hid/hid-penmount.c @@ -0,0 +1,51 @@ +/* + * HID driver for PenMount touchscreens + * + * Copyright (c) 2014 Christian Gmeiner + * + * based on hid-penmount copyrighted by + * PenMount Touch Solutions + */ + +/* + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License as published by the Free + * Software Foundation; either version 2 of the License, or (at your option) + * any later version. + */ + +#include +#include +#include "hid-ids.h" + +static int penmount_input_mapping(struct hid_device *hdev, + struct hid_input *hi, struct hid_field *field, + struct hid_usage *usage, unsigned long **bit, int *max) +{ + int mapped = 0; + + if ((usage->hid & HID_USAGE_PAGE) == HID_UP_BUTTON) { + hid_map_usage(hi, usage, bit, max, EV_KEY, BTN_TOUCH); + mapped = 1; + } + + return mapped; +} + +static const struct hid_device_id penmount_devices[] = { + { HID_USB_DEVICE(USB_VENDOR_ID_PENMOUNT, USB_DEVICE_ID_PENMOUNT_6000) }, + { } +}; +MODULE_DEVICE_TABLE(hid, penmount_devices); + +static struct hid_driver penmount_driver = { + .name = "hid-penmount", + .id_table = penmount_devices, + .input_mapping = penmount_input_mapping, +}; + +module_hid_driver(penmount_driver); + +MODULE_AUTHOR("Christian Gmeiner "); +MODULE_DESCRIPTION("PenMount HID TouchScreen driver"); +MODULE_LICENSE("GPL");
