Input: usbtouchscreen - avoid unresponsive TSC-30 touch screen This patch fixes a problem in the usbtouchscreen driver for DMC TSC-30 touch screen. Due to a missing delay between the RESET and SET_RATE commands, the touch screen may become unresponsive during system startup or driver loading. According to the DMC documentation, a delay is needed after the RESET command to allow the chip to complete its internal initialization. As this delay is not guaranteed, we had a system where the touch screen occasionally did not send any touch data. There was no other indication of the problem. The patch fixes the problem by adding a 150ms delay between the RESET and SET_RATE commands.

Input: usbtouchscreen - separate report and transmit buffer size handling This patch supports the separate handling of the USB transfer buffer length and the length of the buffer used for multi packet support. For devices supporting multiple report or diagnostic packets, the USB transfer size is now limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the configured report packet size as before. This fixes an issue where event reporting can be delayed for an arbitrary time for multi packet devices. For instance the report size for eGalax devices is defined to the 16 byte maximum diagnostic packet size as opposed to the 5 byte report packet size. In case the driver requests 16 byte from the USB interrupt endpoint, the USB host controller driver needs to split up the request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte. When the first transfer is answered by the eGalax device with not less than the full 8 byte requested, the host controller has got no way of knowing whether the touch controller has got additional data queued and will issue the second transfer. If per example a liftoff event finishes at such a wMaxPacketSize boundary, the data will not be available to the usbtouch driver until a further event is triggered and transfered to the host. From user perspective the BTN_TOUCH release event in this case is stuck until the next touch down event.

Input: usbtouchscreen - initialize eGalax devices Certain eGalax devices expose an interface with class HID and protocol None. Some work with usbhid and some work with usbtouchscreen, but there is no easy way to differentiate. Sending an eGalax diagnostic packet seems to kick them all into using the right protocol for usbtouchscreen, so we can continue to bind them all there (as opposed to handing some off to usbhid). This fixes a regression for devices that were claimed by (and worked with) usbhid prior to commit 139ebe8dc80dd74cb2ac9f5603d18fbf5cff049f ("Input: usbtouchscreen - fix eGalax HID ignoring"), which made usbtouchscreen claim them instead. With this patch they will still be claimed by usbtouchscreen, but they will actually report events usbtouchscreen can understand. Note that these devices will be limited to the usbtouchscreen feature set so e.g. dual touch features are not supported. I have the distinct pleasure of needing to support devices of both types and have tested accordingly.

Input: usbtouchscreen - fix eGalax HID ignoring 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>

Input: usbtouchscreen - fix TSC-10 DM USB controllers without EEPROM 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.

Input: usbtouchscreen - fix buffer overflow, make more egalax work 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.
