According to this manual: http://source.android.com/devices/tech/input/input-device-configuration-files.html idc file can have name like
/system/usr/idc/Vendor_XXXX_Product_XXXX_Version_XXXX.idc
So I just search through the sys for the vendor, product and version id. Found them here:
/sys/devices/platform/omap/usbhs_omap/ehci-omap.0/usb1/1-1/1-1.1/1-1.1.3/1-1.1.3:1.0/input/input4/id
According to that ids my file have such name: Vendor_0596_Product_0001_Version_0410.idc
