I found these USB requests... for usb_control_message() #define CMD_EC168_RAM 0x00 //RW- Read/Write RAM (Firmware go to addr 0-0x1EFF)#define CMD_EC168_GETSTATUS 0x01 //R-- ex: dfu_ctrl_get(device,0x01,0x0000,0x01A0,buffer,0x1A);#define CMD_EC168_STREAM 0x03 //R-X ex: dfu_ctrl(device,0x03,0/0x20,0xFF00); // disable/enable streaming #define CMD_EC168_SET_POWER 0x04 //--X ex: dfu_ctrl(device,0x04,0/1,0x0008); // disable/enable LED // indexes seen: 206,208,8,9,A,B#define CMD_EC168_UNKNOWN 0x10 //--X ???#define CMD_EC168_READ_BUF 0x20 //R-- ex: dfu_ctrl_get(device,0x20,0x0000,0x01A0,buffer,0x1A); #define CMD_EC168_WRITE_BUF 0x21 //-W- #define CMD_EC168_SET 0x30 //--X ex: dfu_ctrl(device, 0x30, 0x0709, 0x1A); R Read BufferW Write BufferX Set Value/Exec (without buffer) Updated http://www.linuxtv.org/wiki/index.php/E3C_EC168#Uploading_Firmware_to_the_device The first USB request (0x00) can set/get the RAM... so we cancompare/check uploaded firmware Hope to find some docs on the EC168/firmware asm language... could benice to reverse it to understand available features... _______________________________________________linux-dvb mailing listlinux-dvb@xxxxxxxxxxxxxxx://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
