Just buy some supported USB hardware or a BeagleboneBlack we talked about in our last discussion on April 5th. You provide no URL to the silicon labs hw and you again stick on that slcan stuff. Do you really expect anyone to google that hardware for you to provide a free-of-charge hardware compatibility service?

Checking the example above the driver.rar package contained a PDF with USB (Serial port) to CAN protocol defines Serial port 1228800bps 8 data bit 1 stop bit No parity Default baud rate of CAN:250kbsp Send and receive data packet format No. Definition Remark 0 Packet header 0xaa 1 Packet header 0x55 2 Type 0x01- Transmitting and receiving data 3 Frame type 0x01- Standard frame,0x02- Extended frame 4 Frame format 0x01-ata frame,0x02- Remote Frame 5 Frame ID data 1 1~8bit 6 Frame ID data 2 9~16bit 7 Frame ID data 3 17~24bit 8 Frame ID data 4 25~32bit 9 Length To send or receive data length of CAN bus(0~8) 10 Data 1 CAN send or receive data 1 11 Data 2 CAN send or receive data 2 12 Data 3 CAN send or receive data 3 13 Data 4 CAN send or receive data 4 14 Data 5 CAN send or receive data 5 15 Data 6 CAN send or receive data 6 16 Data 7 CAN send or receive data 7 17 Data 8 CAN send or receive data 8 18 Reserve 0 19 Check Red part of the data accumulation and checksum So this is far away from slcan and we don't know details about the checksum either.
