2009-02-28Input: usbtouchscreen - fix eGalax HID ignoringDaniel Ritz
Commit ec42d4481e36cbdb5b2801f957e678211a9e5ae2 broke usbtouchscreen for some eGalax/EETI devices that claim to be HID, but are not. Devices confirmed to be real HID have the class set to HID and the protocol set to 'mouse'. Some have HID class but protocol set to 'none'. Those are not HID and should be driven by usbtouchscreen. Fix the device ignoring macro by adding match for the protocol too. Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-01-10Input: usbtouchscreen - allow reporting calibrated dataDan Streetman
This patch adds a module parameter to report either the raw coordinate data or the hardware-calibrated coordinate data for MicroTouch/3M touchscreens. The default is set to the raw coordinates for backwards compatibilty. Signed-off-by: Dan Streetman <ddstreet@ieee.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2008-11-19Input: usbtouchscreen - fix TSC-10 DM USB controllers without EEPROMNuno Lucas
The usbtouchscreen module implements a driver for the TSC-10 DM USB touchscreen controllers, but assumes a 2-byte response for the CMD_RESET and CMD_RATE commands, when they can be only a single byte when no EEPROM is connected. The driver worked with an earlier controller revision, but new revisions of the controller fail. It seems the problem is that the early controller had the SEL4/EEPROM-CS pin high, but the new controller has it down, making the response different. Without the fix, the controller would answer the single byte 0x06 (ACK), making the init fail with -ENODEV because buf[1] is 0xFF (as initialized before). As the single byte is the only thing we need to check it was ok, there is no need to verify the second byte. The [0x15 0x01] case is the NAK [0x15] response for when there is no data in the EEPROM [bit-0 of second byte set], so I let that be, as I don't have any controller with an EEPROM. With this patch, both the earlier and latest controller work the same. Note: This was previously submited as BUG #11961 [1] on the bugzilla tracker, but rebased to version 2.6.27.4 and with unnecessary comments and printk's removed.

2008-07-03Input: usbtouchscreen - ignore eGalax screens supporting HID protocolDaniel Ritz
The newer versions of the eGalax/EETI screen implement the HID protocol. The device IDs are still the same, but the USB interface descriptor shows the device being of HID class. Change usbtouchscreen to ignore the HID models as they are handled properly by usbhid. Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2008-01-17Input: usbtouchscreen - fix buffer overflow, make more egalax workDaniel Ritz
Fix a buffer overflow in mutli-packet handling code. The overflow can only happen with eGalax devices and is even there very unlikely (only non-report packet are affected any only when truncated after the first byte). Also changes the mutli-packet handling code not to drop unknown packets, but rather just drop one byte. This allows synchronizing on report packets in the data stream. It's required for some egalax devices to work at all. Also remove the pointless 'flags' member of the device struct and set the version number to 0.6, plus some minor cleanups.

get rid of input BIT* duplicate defines use newly global defined macros for input layer. Also remove includes of input.h from non-input sources only for BIT macro definiton. Define the macro temporarily in local manner, all those local definitons will be removed further in this patchset (to not break bisecting).

2007-09-06Input: usbtouchscreen - correctly set 'phys'Vladimir Shebordaev
This patch fixes a nasty typo in usbtouchscreen driver. The typo is inherited from the original mtouchusb. It used to make the input subsytem to incorrectly report the physical device ids to userspace that in turn is very confusing for, e.g. XInput hotplug facilities in setups with multiple identical touchscreens.
