I am trying to use software to program a scanner radio (BCD396t and UASD software). The software installs and seems to run properly, reading and writing database files. But I cannot connect to the scanner, through a USB-to-serial cable. OS: ubuntu-8.10, kubuntu-8.10, debian/lenny (tried them all) lsusb identifies the cable as follows: Bus 002 Device 002: ID 067b:2303 Prolific Technology, Inc.

hello everyone, I've been testing the NUT solution as opposed to the undocumented LanSafe application to control my Eaton UPS. I am on a Slackware 13.37 system with a 2.6.37.6 kernel. NUT version is 2.4.3 . I installed the tarball by compiling it directly on my system (as a slackbuild package). The UPS is an Eaton Powerware 9155, but I don't know how to obtain the manufacturing date. The

OK, I am running CentOS 6 on my Laptop and Desktop, presently kernel version 2.6.32-696.20.1.el6.x86_64 (yes, a version or so out of date -- I'll probably do an update soon -- non-trivial since my Internet connection is via dialup). I recently bought a couple of Adafruit Arduino compatibles, a Flora and a Metro 328. Hooking up the Flora and the Metro to a Raspberry Pi running Raspbian

I have a 40GB IDE laptop hard drive I took out of a dead laptop and I was hoping to put some good use to it. The drive is inside a USB drive enclosure and I carry it in my laptop bag. Its not big enough to be a backup drive, and generally too big to BIOS boot from. The chipset on the enclosure is from Prolific and registers as a "Mass Storage Device" I haven't had good luck with

Wine does great job for GUI on screen (PC Oscilloscope) But, can't USB connect to external hardware device that has FTDI 245AM chip in it. See device in /dev/ttyUSB0. See device in lsusb, also in lsmod. Did normal linking, ln -s /dev/ttyUSB0 /.wine/dosdevices/com3. No luck. See the link with: ls -al of dosdevices. Using COM3 because in Windows registry in Wine, it says COMPORT=3 Any help?

Hello Charles and Douglas, I really believe that BZ2200-BR model is the same as mine BZ1200-BR, with different capacity. If you see the BZ2200-BR specs you will notice the manufacturer "APC-Microsol". Those no-breaks have a USB port in it, but in fact it is a serial<->usb cable, usually uses the port "/dev/cuaU0". In mine, the serial<->usb chip is from FTDI, and

Got a community question at https://github.com/networkupstools/nut/issues/2466 with at least two users (and UPSes) in trouble. Curiously, they identify as 067b:2303 Prolific Technology like a common USB-Serial dongle brand. Experiments with blazer and nutdrv-qx got no reasonable response from the devices.

Hi. I have some problems with USB->Serial FTDI FT232BM chip drivers on FreeBSD 7.0... FreeBSD recognize the USB device, but when I making connection to /dev/cuaU0 or /dev/ttyU0 I cant send & receive any data from device. cu -l/dev/cuaU0 -s9600 - No response at all, can't even quit the program cu -l/dev/ttyU0 -s9600 - Sometimes working, but few bites/chars after - no response...
