Yes, the result is the same. # cu -s 115200 -l /dev/cuaU0 Connected If I understand correctly from https://www.bit0.com/tmp/usbmon-ciscoasa-verbose.txt The Leftover Capture Data: 80250000000008 and frame[1] WRITE 7 bytes 0000 80 25 00 00 00 00 08 -- -- -- -- -- -- -- -- -- |.%..... is something like configuration data, where 80 25 is 0x2580 == 9600, so it should work with default speed. When I use 115200, I see this: 09:27:52.657367 usbus0.2 SUBM-CTRL-EP=00000000,SPD=FULL,NFR=2,SLEN=16,IVAL=0 frame[0] WRITE 8 bytes 0000 21 20 00 00 00 00 07 00 -- -- -- -- -- -- -- -- |! ...... | frame[1] WRITE 7 bytes 0000 80 25 00 00 00 00 08 -- -- -- -- -- -- -- -- -- |.%..... | flags 0x10 <PROXY_BUFFER|0> status 0xca1a3 <OPEN|TRANSFERRING|STARTED|CONTROL_XFR|CONTROL_HDR|BDMA_ENABLE|BDMA_SETUP|CAN_CANCEL_IMMED|DOING_CALLBACK|0> 09:27:52.657711 usbus0.2 DONE-CTRL-EP=00000000,SPD=FULL,NFR=2,SLEN=0,IVAL=0,ERR=0 frame[0] WRITE 8 bytes frame[1] WRITE 7 bytes flags 0x10 <PROXY_BUFFER|0> status 0xca1a1 <OPEN|STARTED|CONTROL_XFR|CONTROL_HDR|BDMA_ENABLE|BDMA_SETUP|CAN_CANCEL_IMMED|DOING_CALLBACK|0> 09:27:52.760528 usbus0.2 SUBM-CTRL-EP=00000000,SPD=FULL,NFR=2,SLEN=16,IVAL=0 frame[0] WRITE 8 bytes 0000 21 20 00 00 00 00 07 00 -- -- -- -- -- -- -- -- |! ...... | frame[1] WRITE 7 bytes 0000 00 C2 01 00 00 00 08 -- -- -- -- -- -- -- -- -- |....... | flags 0x10 <PROXY_BUFFER|0> status 0xea1a3 <OPEN|TRANSFERRING|STARTED|CONTROL_XFR|CONTROL_HDR|BDMA_ENABLE|BDMA_SETUP|CURR_DMA_SET|CAN_CANCEL_IMMED|DOING_CALLBACK|0> 0x01c200 == 115200. -- WBR, Andrey V.
