Dear list. I have an USB smartcard reader that emulates a serial port. It uses the uftdi.ko kernel module and creates the following device nodes when plugged in. System is FreeBSD 7.2-RELEASE-p3 amd64. crw-rw---- 1 uucp dialer 0, 110 Jan 14 19:27 /dev/cuaU0 crw-rw---- 1 uucp dialer 0, 111 Jan 7 14:01 /dev/cuaU0.init crw-rw---- 1 uucp dialer 0, 112 Jan 7 14:01 /dev/cuaU0.lock crw------- 1 root wheel 0, 107 Jan 14 19:25 /dev/ttyU0 crw------- 1 root wheel 0, 108 Jan 7 14:01 /dev/ttyU0.init crw------- 1 root wheel 0, 109 Jan 7 14:01 /dev/ttyU0.lock dmesg output: ucom0: <FTDI USB <-> Serial, class 0/0, rev 1.10/4.00, addr 2> on uhub5 I'm trying to access it with a linux program and the program initializes and manages to read at least some basic info from the card but any further communication with the card results in the following message regardless of what device node I use: linux_sys_futex: unknown op 265 Same software and reader works on a pure linux machine. Does anyone have any hints on what I can do to try to track this problem down? Some clarification on what the difference is between cuaU0 and ttyU0 would be appreciated too and which of them I should use primarily. Regards Morgan
