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:
hw.usb.quirk.0="0x05a6 0x0009 0 0xffff UQ_ASSUME_CM_OVER_DATA"
and I also tried
# usbconfig -d ugen4.3 add_quirk UQ_ASSUME_CM_OVER_DATA
but it doesn't make any difference. It does show up as a new entry in
"usbconfig dump_device_quirks" but doesn't solve the problem.
Connecting the firewall to a Mac with the same cable works fine, so I know
the cable is good and that I'm using the right bit rate (9600).
Here are some other usbconfig dumps if these are useful in pointing me in
the right direction (sorry these have lines longer than 80 columns):
