Ok, the driver named usbtouchscreen.ko works as well. Need to be patched <https://lkml.org/lkml/2007/3/24/54> to accept X-Y swap and X invert, Y invert. In this case, the ismod line must be called with arguments, for example
insmod /system/vendor/modules/usbtouchscreen.ko swap_xy invert_y For the calibration <https://a20androidincar.wordpress.com/configuring-the-touchscreen/>, same thing: work into usbtouchscreen.c static struct usbtouch_device_info usbtouch_dev_info[] = { #ifdef CONFIG_TOUCHSCREEN_USB_EGALAX [DEVTYPE_EGALAX] = { .min_xc = 0x003e, .max_xc = 0x079d, .min_yc = 0x0069, .max_yc = 0x0735, .rept_size = 16, .process_pkt = usbtouch_process_multi, .get_pkt_len = egalax_get_pkt_len, .read_data = egalax_read_data, }, #endif with the values x_min, x_max, y_min, y_max, found with this command in root: getevent -l and touching the 4 corners -> Top Left, Top Right, Bottom Right, Bottom Left The final step consit to create a file named Vendor_aaaa_Product_bbbb.idc with aaaa = your usb device Vendor bbbb = your usb device Product -> cat /proc/bus/input/devices to find Vendor and Product This .idc file must be in /system/usr/idc folder, -> or placed before build in /ANDROID/android/out/target/product/sugar-lemaker/system/etc , with an order to copy it in the file sugar_lemaker.mk file: PRODUCT_COPY_FILES += \ [...] device/softwinner/sugar-lemaker/Vendor_0eef_Product_0001.idc: system/usr/idc/Vendor_0eef_Product_0001.idc For multi touch, I work on this but I have found a link here <http://www.chalk-elec.com/?p=2028>.
