I'm curious whether the cisco side is truly a generic usb serial and the problem is that the umodem driver is trying to do modem-specific things which the cisco side is getting confused by. A way to test that theory would be to add the cisco's vid/pid to the ugensa driver (sys/dev/usb/serial/ugsena.c). If that works, I'm not sure it's so much a solution as a clue. I've always wanted a way to add VID/PID combos to ugsensa's internal list on the fly, like via hints or sysctl or something, to make this kind of quick test easier. But I never find time to add the feature. -- Ian _______________________________________________ freebsd-usb@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
