This is a general problem with the low-cost Prolific processor chip and drivers. You should invest in a better USB to Serial adapter (http://www.usconverters.com/index.php?main_page=product_info&cPath=67&products_id=244) with a FTDI chipset. It costs a bit more but its well worth the money. The drivers for the FTDI chipset are well documented and compatible with most devices.

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

Hello I installed CentOS 8 on a clean system.I tested a pl2303 ic with different PID. If i use HP PID 0x4349,i will receive junk data after connecting, but the pl2303 PID 0x2303 work normally. Does someone know about how to fix this situation? thanks Test video link: HP VID/PID - https://www.dropbox.com/s/9hj7im5tr4e1v1u/HP.mp4?dl=0 Prolific VID/PID -

Hello, I have two SMS PowerVision PV2200 BIFX, that came with a serial port, I used a serial - usb conversor to conect it to my pc it recognized as: lsusb -s 001:005 -vvv Bus 001 Device 005: ID 067b:2303 Prolific Technology, Inc.

I have a USB to serial converter attached to my box. pl2303: Prolific PL2303 USB to serial adaptor driver if I login to the box and send/receive serial commands over this unit it works without error EVERY time. however, if I run the same command set from with-in the extensions.conf with System() I get errors in dmesg like "pl2303 ttyUSB0: pl2303_open - failed submitting read urb, error

I am far from expert on these matters. But have a couple questions: 1. Are you sure that /dev/ttyUSB0 exists and is the result of the Prolific USB->serial converter? For example, if you yank the Prolific and reboot, is /ttyUSB0 there still? It is possible that there is another /dev/ttyUSBx out there.I doubt this but wonder. 2. I have recently been fuddled due to permission problems of

Hello, everyone - I have an old Windows app - a ship navigation program - that needs to see GPS input on a serial port (it was written in the pre-USB days.) My laptop, however, has no serial ports - but this same program, when run on a friend's Windows box, can read the GPS info from the USB-connected GPS via the "USB-Serial Driver". This is one of the frustrating bits of this

Hi All, I have an mge pulsar esv 14+ rackmount UPS connected via straight through serial cable to a USB to serial adaptor (My motherboard does not have a native RS232 port). I am running Ubuntu Server 9.04 x64, and nut 2.4.1-2ubuntu4 installed via APT. I am getting the error: Poll UPS [ups1 at localhost] failed - Driver not connected My conf files: (ups.conf) [ups1] driver=mge-utalk

    Lately I replaced my 10+-year-old server with a nano-ITX-type one that has USB but not old serial ports.  I connected my FE700VA to DB25-to-9-to-USB cables, but haven't been able to set it up. Apparently my DB9-to-USB cable (Prolific Technology, Inc. PL2303 Serial Port) has issues needing old software (setserial?) and some new software (fconfigure) being changed.  Has anyone managed

Ubuntu creates /dev/ttyUSB0 for me when I plug in the usb-to-serial-adapter. I have a symbolic-link to /dev/ttyUSB0 from 'dosdevices/com1'. What is new in 10.04 Ubuntu is that I have to sudo chmod o+r and sudo chmod o+w on /dev/ttyUSB0 every time before I start the app which uses that serial line. ttyUSB0 goes away when I unplug the serial adapter from the USB port or shut down the
