Guys, As I could’n some the error I tried another approach. I checkout commit 80ccb51a from 09/11/2013 as I know it is a working version for sms2270 device but not so newer. I copy siano files from commit 80ccb51a to my kernel tree (3.4.75) and I need only disable IR support to compiles without errors. So, I copy my new kernel and modules to device to test, now device is found but...: root@awsom:~# insmod smsdvb.ko insmod: error inserting 'smsdvb.ko': -1 Unknown symbol in module root@awsom:~# insmod smsmdtv.ko root@awsom:~# insmod smsusb.ko dmesg: [ 404.935357] smsdvb: Unknown symbol smsendian_handle_tx_message (err 0) [ 404.940520] smsdvb: Unknown symbol smscore_get_device_mode (err 0) [ 404.954893] smsdvb: Unknown symbol smscore_register_client (err 0) [ 404.959986] smsdvb: Unknown symbol sms_board_led_feedback (err 0) [ 404.974160] smsdvb: Unknown symbol sms_board_power (err 0) [ 404.978477] smsdvb: Unknown symbol sms_get_board (err 0) [ 404.983893] smsdvb: Unknown symbol smscore_unregister_hotplug (err 0) [ 405.001147] smsdvb: Unknown symbol smscore_putbuffer (err 0) [ 405.007305] smsdvb: Unknown symbol smsendian_handle_rx_message (err 0) [ 405.012321] smsdvb: Unknown symbol sms_board_lna_control (err 0) [ 405.020188] smsdvb: Unknown symbol smsclient_sendrequest (err 0) [ 405.026278] smsdvb: Unknown symbol smscore_unregister_client (err 0) [ 405.030765] smsdvb: Unknown symbol sms_board_event (err 0) [ 405.036086] smsdvb: Unknown symbol sms_board_setup (err 0) [ 405.040981] smsdvb: Unknown symbol smscore_get_board_id (err 0) [ 405.047036] smsdvb: Unknown symbol smscore_register_hotplug (err 0) [ 415.683285] smsusb_init_device: line: 372: Unspecified sms device type!
