Hi Please understand my wish list! Regarding FTDI Library 0.4.16 versus the FTDI Library 0.4.13 The V16 & V13 libraries. Which is better. They both have serious defiencies V16 does indeed allow ttyUSB0 to be reused SUCCESSFULLY! V13 does NOT allow ttyUSB0 to be reused SUCCESSFULLY! V16 does indeed reset every device! V13 does NOT reset every device! (only the selected ones if new state is to be different) Wish list .... to have the benefit of both in the one Version My want list to to switch Power wires before data wires. If you physically plug in my USB dongle.... power is connected before data. IE pin 1 & 4 connects before 2 & 3. (2 & 3 gold connectors are offset inwardly from 1 & 4 ) The module: I have power wire "red & black" on relay 1 & 2 & data on 3 & 4 So the code below on Ver 13 ... it works like I want , BUT on Ver 16 it doesn't # lrelayset -sFTSIL4VG,3 # sleep 1 # lrelayset -sFTSIL4VG,15 Also for me 12 & 15 should also do the same The 2 sets of code below behaves the same in V13 # lrelayset -sFTSIL4VG,3 # sleep 1 # lrelayset -sFTSIL4VG,12 ######################################## # lrelayset -sFTSIL4VG,3 # sleep 1 # lrelayset -sFTSIL4VG,15 ----- Original Message ----- From: Roger Salisbury To: ftd...@li... Sent: Sunday, December 13, 2009 4:55 PM Subject: Linux support for FT232RL not production ready Hi Not sure if Bill Ryder or Greg Kroah-Hartman or some of the other names fromm google searches can help. As is Linux specific but the only support thus far is http://www.ftdichip.com/FTSupport.htm#DriverSupport Which hasn't helped yet. So Any other help greatly appreciated. I have a problem using Linux with the device from http://www.dontronics-shop.com/super4-usb-relay-module.html Linux support for the Super4 USB Relay Module .. using FT232RL would it be considered production ready? The Super4 USB Relay Module does work to a point on "puppy" linux & a few others . I want to use this device on Ubuntu910. I want to be able to powercycle a broadband USB modem from the CLI . BUT Both devices want to use ttyUSB0. If ttyUSB0 is NOT free (in use) the USBmodem will select ttyUSB1. But USB0 becomes free (or considered to be free at some level ) when it shouln't & will select ttyUSB0. Most Linux installation it kind of works. RH5, RH4, FC11,Debian Lenny (even puppy linux has this same problem) At least All 4 relays can be set & unset from the CLI (command line interface). The problem is :: on plugging in the USB cable an entry in /dev appears. (/dev/ttyUSB0) The entry thereafter disappears when the device is accessed or set or unset. #lrelayset -l the above command lists the number of devices with the SerialNumbers. After issuing the command the (/dev/ttyUSB0) disappears. So subsequent USB devices want to use the same (/dev/ttyUSB0) device, causing conflicts it seems. Perhaps that is normal, BUT this seems bizzare to me! The Setup on linux is simple : Any modern Linux distro with 2 supplementary files /usr/bin/lrelayset -l /usr/lib/libftd2xx.so linked to libftd2xx.so.0.4.13 (http://emx.net.au/page426.htm) On installations that don't work. IE where the "lrelayset -l" doesn't work, the similiarities are very similiar to a working?? system. Below are listing from "lsusb -v" on two systems. firstly kernel messages to "/var/log/messages" compared. Fc11 has 5 uniq lines & ubuntu910 has 4. 10 lines are common to both. So ubuntu must be close to working ????
