Sorry about the brainfart. I changed the device in the script: root@kg-core1# grep ^DEV_NODE dymoprint2 DEV_NODE = "/dev/ulpt0" and now it works: root@kg-core1# python dymoprint2 "4port USB2.0 hub" "38-5663" [96, 0, 18, 100, 13, 220, 0, 0] (Tes, I get the printout too) Thanks for the hint! -- Torfinn Ingolfsen ___ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
