1 ================ 2 mtouchusb driver 3 ================ 4 5 Changes 6 ======= 7 8 - 0.3 - Created based off of scanner & INSTALL from the original touchscreen 9 driver on freecode (http://freecode.com/projects/3mtouchscreendriver) 10 - Amended for linux-2.4.18, then 2.4.19 11 12 - 0.5 - Complete rewrite using Linux Input in 2.6.3 13 Unfortunately no calibration support at this time 14 15 - 1.4 - Multiple changes to support the EXII 5000UC and house cleaning 16 Changed reset from standard USB dev reset to vendor reset 17 Changed data sent to host from compensated to raw coordinates 18 Eliminated vendor/product module params 19 Performed multiple successful tests with an EXII-5010UC 20 21 Supported Hardware 22 ================== 23 24 :: 25 26 All controllers have the Vendor: 0x0596 & Product: 0x0001 27 28 29 Controller Description Part Number 30 ------------------------------------------------------ 31 32 USB Capacitive - Pearl Case 14-205 (Discontinued) 33 USB Capacitive - Black Case 14-124 (Discontinued) 34 USB Capacitive - No Case 14-206 (Discontinued) 35 36 USB Capacitive - Pearl Case EXII-5010UC 37 USB Capacitive - Black Case EXII-5030UC 38 USB Capacitive - No Case EXII-5050UC 39 40 Driver Notes 41 ============ 42 43 Installation is simple, you only need to add Linux Input, Linux USB, and the 44 driver to the kernel. The driver can also be optionally built as a module. 45 46 This driver appears to be one of possible 2 Linux USB Input Touchscreen 47 drivers. Although 3M produces a binary only driver available for 48 download, I persist in updating this driver since I would like to use the 49 touchscreen for embedded apps using QTEmbedded, DirectFB, etc. So I feel the 50 logical choice is to use Linux Input. 51 52 Currently there is no way to calibrate the device via this driver. Even if 53 the device could be calibrated, the driver pulls to raw coordinate data from 54 the controller. This means calibration must be performed within the 55 userspace. 56 57 The controller screen resolution is now 0 to 16384 for both X and Y reporting 58 the raw touch data. This is the same for the old and new capacitive USB 59 controllers. 60 61 Perhaps at some point an abstract function will be placed into evdev so 62 generic functions like calibrations, resets, and vendor information can be 63 requested from the userspace (And the drivers would handle the vendor specific 64 tasks). 65 66 TODO 67 ==== 68 69 Implement a control urb again to handle requests to and from the device 70 such as calibration, etc once/if it becomes available. 71 72 Disclaimer 73 ========== 74 75 I am not a MicroTouch/3M employee, nor have I ever been. 3M does not support 76 this driver! If you want touch drivers only supported within X, please go to: 77 78 http://www.3m.com/3MTouchSystems/ 79 80 Thanks 81 ====== 82 83 A huge thank you to 3M Touch Systems for the EXII-5010UC controllers for 84 testing!
