I'm trying to get the USB console of a Cisco ASA 5506-X firewall (not
terribly obscure hardware) talking to FreeBSD, and having some trouble. The
relevant dmesg at probe time is:
umodem0 on uhub7
umodem0: <Cisco Cisco USB Console, class 2/0, rev 2.00/0.00, addr 3> on
usbus4
umodem0: data interface 1, has no CM over data, has no break
...and /dev/cuaU2 is created, and I can connect to it using cu, but then
nothing happens. As in, hitting enter to get a prompt just sits there.
(cuaU1 and cuaU0 are a separate two-port USB serial adapter and that one
works fine, it's using uftdi instead of umodem...)
The "has no CM over data" looks worrying. I attempted to add a quirk, but
either it isn't working or I didn't do it right. In /boot/loader.conf I
tried:
Hi,
Try using usbdump to figure out what is going on.
usbdump -i usbusX -f Y -s 65536 -vvv
X and Y are the numbers in ugenX.Y printed in dmesg.
It will dump all low level communication with the firewall. Maybe it needs
some special character escaping to respond, or maybe it needs to set the RTS
CTS bits.
OK, here's a dump while running "cu -s 9600 -l /dev/cuaU2", hitting return
about a dozen times, and then ~. to quit.
I'm not sure how to interpret this as I'm not familiar with USB stack
innards. (I'm more of a tcpdump guy.)
Oh, and I suck for not mentioning that this is FreeBSD 11.1-p1 amd64.
On macOS the same cu command (for /dev/cu.usbmodem1411) works fine without
any other magic. I don't know where their equivalent of usbdump is,
unless it's buried in Xcode somewhere. I can give Ubuntu a shot too, once
I dust that hardware off and power it up...
