Solving Prolific PL-2303 USB to Serial Comm Port installation issues

Hello everybody,
More and more machines are comming without Parallel and serials ports, they are comming with USB external ports only.
Some have the RS-232 and Parallel headers in the motherboard, and that should last for about a year I think.
At any rate, the issue I was facing is the following:
(a) Installing Prolific PL-2303 USB to Serial Comm Port on Windows XP Pro SP3 works OK and system runs fine. there are some capacity issues regarding the buffer size, but that is another post.
(b) Installing on WEPOS 1.1 SP3 on some motherboards (Older ones) that have at least the Parallel headers and a serial port, the device also works as with (a)
(c) Installing on WEPOS 1.1 SP3 with a machine with only external USB's (no parallel / serial port or headers). The installation process runs OK. but when the device
is plugged I get the following error message:
"An error ocurred during the installation of the device"
"A service Installation section in this INF is invalid"
(d) Installing on POSReady 2009. I get the same as with (c)
This is how I solved, after many frustrating reboots with the same message about the INF section and multiple Prolific drivers tried. I started digging windows:
(1) Find the setupapi.log and read it, if the OS is a fresh install it will not be too long.
(2) Read this:
#-166 Device install function: DIF_SELECTBESTCOMPATDRV.
#I063 Selected driver installs from section [ComPort] in "c:\windows\inf\oem15.inf".
#I320 Class GUID of device remains: {4D36E978-E325-11CE-BFC1-08002BE10318}.

(3) So it was the serenum.sys file that Windows needed to find in the ..\system32\drivers folder. I got the serenum.sys from one of the temporary folders created by the installation process.
(3a) So, I think that windows installs this sys file if it recognizes the motherboard has at least one parallel or serial port.
(4) So good luck when installing your serial device to your POS solution. I will open another thread if I have problems with the buffer size of the device.

Hello Terry,
Indeed, they were not intended as POS system, the EEE Top machines are candy to the eye, but for my taste they do not work in POS environment (I give them 1 year before they pop). Regarding the other, well competition is tought, so you have to get creative in order to keep costs down, and this one can be used as a waiter stations, that do not need heavy serial comunications.
Anyways, the POSReady does not install these system files if the installation does not detect a serial or parallel port (which make sense, as why would it install drivers for a device that is not detected). I posted this for others to be aware of this when they select the hardware that will be offered to their customers, as good old "on mother-board" serial and parallel ports cannot be beaten by their USB imitations (IRQ and memory addressing processing are needed for end devices to function properly).
Have a great weekend,
Humberto

USB Support for RT

The only functionality of RT USB is mass storage. It would be helpful to add at least RAW Data USB support to use USB port for connecting i.e. USB / RS232 adapter. Many analyzers use integrated serial/USB converter chips to transfer data to PC, because no need of specialized driver (you get the driver with the chip). The ability of RAW USB support allows to connect these analyzers to cRIOs and RT PC Targets.

For VxWorks-based cRIO devices, we do support a USB-Raw functionality. You configure the USB device through MAX and you are then able to use NI-VISA to communicate with the device; it then requires the end-user to write a "driver" to communicate with the device using NI-VISA. It's fairly easy to do, but can be a support nightmare if you don't have the detailed spec sheet on the device. We're currently looking into options for providing this for PXI and Desktop RT systems.
I am not sure how "no specialized driver" fits in with "you get the driver with the chip" - USB/RS232 adapters generally use a USB-Serial bridge inside them, usually an FTDI or Prolific chipset. FTDI does not provide open source drivers, though someone reverse-engineered the device and wrote a driver in Linux that "supports" it - we would not be able to support FTDI devices under RT because there are no available open-source drivers for it (that's intentional on the part of FTDI). Prolific devices could be supported, at extra cost and development effort to port the Prolific drivers to RT. Just because a driver is "included" with a device for Windows doesn't mean it's not a "specialized driver" or that we can even use it on a platform not supported by the manufacturer (like RT).
We are always looking at ways we can improve LabVIEW Real-Time, and due to common request this is one of the areas we're investigating.

Prolific vista drivers not working

Prolific usb serial driver

Trying to re-install the prolific USBSerialDriver 1.2.1 needed with a GlobalSat BU-353 GPS antenna. It used to work, and this is the correct driver and version. However, when running the installer it tells me it cannot install to the HD because "a newer version of the driver exists on the disk".
I have used kextunload to unload, and then I removed, all USB serial drivers, examined the /System/Library/Receipts/ and removed all copies of any serial drivers from the HD, checked for Preferences, re-started, and the installer still complains.
Happens in both 10.6.5 & 10.6.6
Any suggestions for how I go about solving this one?
Is there a way to override an installer?

I have one usb-serial adapter which also seem to have a pl2303 and this is what I get:
usb 3-2: new full-speed USB device number 3 using ohci-pci
usbcore: registered new interface driver usbserial
usbcore: registered new interface driver usbserial_generic
usbserial: USB Serial support registered for generic
usbcore: registered new interface driver pl2303
usbserial: USB Serial support registered for pl2303
pl2303 3-2:1.0: pl2303 converter detected
usb 3-2: pl2303 converter now attached to ttyUSB0
According to lsusb this is the converter:
0557:2008 ATEN International Co., Ltd UC-232A Serial Port [pl2303]
I would try to check if the converter is really working on another machine, that one might be broken or a fake.
Edit:
Typo.

Usb to Usb bridge drivers for osx?

I recently acquired a usb bridge. I need to connect this to my pc and macbook. There are drivers on this site (http://www.prolific.com.tw/eng/downloads.asp?ID=30), however the drivers are only for Windows. I need drivers for an intel mac (preferably leopard).
Can someone please help me

Hi and welcome to Discussions,
if Prolific as the manufacturer of the bridge-chip doesn't offer any Mac OSX drivers, then no one will.
I myself have one of these lying around from my PC-days (useless now...).
You can however connect your PC and your Mac using a standard Ethernet cable, see here http://support.apple.com/kb/HT2518

Prolific USB Serial Connector

I have a Prolific USB/serial connector that works fine on my iMac, but when I plug it into a new Mac Mini with Snow Leopard Server, the device doesn't show up.
The device that shows up on my iMac is: cu.PL2303-004014FD. Nothing like that shows up on the Mac Mini.
Anybody else run into this? I know this is an old peripheral, but it works fine on my other machine. Is there something different about how devices are handled on the server version (seems strange, but perhaps...)?
Thanks,
-Mike

Have you tried the most recent drivers? Using these, your device should show up as /dev/tty.usbserial, whether you're in 32-bit or 64-bit mode.
On the off chance you've got an OEM model that uses the PL2303 chipset, you may need to make some minor modifications to the extension to get it to recognize the Product and Vendor code of your slightly-modified hardware. This is a two-step process:
Do a "tail -f /var/log/system.log" and disconnect and reconnect your PL2303. You will see a message from "pcscd" that gives you both codes in hexidecimal. You can always see it in System Profiler, but it might not be as clearly identifiable as the message you get when the unrecognized device gets plugged into your Mac's USB bus.
Edit "/System/Library/Extensions/ProlificUsbSerial.kext/Contents/Info.plist" to update the listed "idProduct" and "idVendor" values to the decimal value of what you gathered in Step 1. You must convert from hex to decimal or nothing will happen.
After a reboot, your serial adapter should appear at /dev/tty.usbserial. This has worked well for me for about a year using an IOGear GUC232A ($22 on Amazon and no current OS X drivers). I am just updating to the new version of the Prolific driver listed at the above URL, so YMMV.
Disclaimer: If you are not prepared or experienced enough to edit an installed System Extension and don't understand the possible harm that could come, even if you do it correctly, I would not recommend attempting this.
Message was edited by: Bafflegab - updated the /dev path for the active device to include the tty prefix.

Commands to FTDI virtual COM port via NI VISA interfere with communication with FTDI chip using D2XX drivers

Hello!
I am trying to communicate with a DLP Design module DLP-USB1232H which uses an FTDI chip. My program uses the D2XX drivers. It works, but...
In another program that runs at the same time, I'm communicating with another instrument via a virtual COM port (VCP) that uses an FTDI UART. In this program, I use the VISA Serial Port functions. It works, too, but...
The first program has the capability of listing all the FTDI devices in the system prior to choosing the right one to communicate with. When the VCP is plugged in, it lists it (FT232R USB UART) along with the DLP-USB1232H and communication with the latter device works. But as soon as the second program sends a command through the VCP, the first program no longer "sees" any FTDI device. It stops working.
I have tried 2 different FTDI VCPs; one a standalone cable and the other built in to the instrument.
I’m using Windows 7 32-bit. My programs are both LabVIEW 8.5 executables.
Is VISA "taking over" the channel to the DLP-USB1232H? Does someone who understands NI's implementation of VISA have any ideas on why VISA is doing this? Or if something else is going on?
I'm also interested in workaround ideas. I've tried a "Prolific" VCP, but most drivers don't work and the one that doesn't give an error in Device Manager doesn't communicate with the instrument.
Cheers
Halden
Solved!
Go to Solution.

Halden,
It really sounds like you have a resource conflict. That occurs when two programs or parts of programs try to use the same device or port at the same time. Your Get Device Function probably tries to open a session with each port (as you increment the index). When it hits a port which is being used by the other driver, it cannot open the session and stops working? Have you examined the errors returned by each program? The VISA drivers will return an error when the port is in use. I do not know about your program or drivers, but I would expect some kind of error. Automatic error handling in LabVIEW will not catch errors from a driver if it does not translate them to LV error clusters. So do not count on automatic error handling, if you use it, to display all possible errors.

Drivers Needed for Tecra A3

Tried knoppix and seems to work except some issues with the drivers of the following:
1.modem driver-Lucent/Agere-Tried kanotix which have builtin drivers-not working either.Does not force load the serial.o
2.usb is detected but does not work
3.usb to serial adapter-very important to me-I have a Prolific brand which works like a breeze in xp
Any suggestions? Thanks!

Hi bongski
The problem is that unit is not supported and if you have some problems using Linux OS you are on your own. In my opinion you should try to find a driver on some support page. Check also general Knnopix support page on http://www.knoppix.net/forum/viewforum.php?f=1 .
Check also http://linux.toshiba-dme.co.jp/linux/index.htm .

5110 - DAU-9P Cable drivers

Hi,
I am trying to use an old 5110 for bulk SMS's, but the software I'm trying to use suggests that in order to use such a cable, I need to install the drivers for the cable first so that it can send AT commands direct to the phone. It's an original Nokia DAU-9P Cable with a DB9 (9-pin serial) connector. I need to use this cable with the phone because no other options are feasible for the project (e.g. Clickatell gateway, newer phone, etc). I have tried the software with a 5100 using a prolific cable (USB, appears as COM3) and this works, but because of the expense of a new phone like this in Zimbabwe, I cannot use one. If anyone knows where I can get the Drivers for the cable it would be much appreciated, otherwise if anyone could help with identifying the oldest phone that would work with a USB DKU-5 cable or similar.
The software I am trying to use is called "SMS Reception Center" and it copies the SMS from the phone immediately upon reception then deletes it, so memory space can be minor (e.g. 5 spaces for SMS's), and for this reason the 5110 was a perfect choice. Help please...
Daniel

I can´t help you, sorry. Only to say that my old Nokia 6150, from 10-1998 still works without any fail! And on all that time, it was only necessary change once the battery for a new one, and it keep´s working. Great phone.

I get the file downloaded (LJEnt-color-M551-Drv-no-installer_12297.exe), i run it, get the security warning and Run. the file extracts - then POOF, the installer is gone.
where did the files go? They aren't on the root of the C: drive, a folder/files were not created on my desktop, no files or folder created in my downloads folder.
I was never asked for a file save location.... ??? really? is this this basic stuff?
Where are the files? this $$$ printer is a brick until i get drivers!
Thanks!

UPDATE- I FOUND THE FILES!!
First of all, HP... i'm not impressed.
All the files for all the drivers are in a series of temp folders...
C:\Users\-myusername-\AppData\Local\Temp\3\7zS4A73
really?
hope this helps someone.

There is no change to this problem after 6 months since the last post. Put simply, and as stated in the previous posts, there is no way to scan a document and receive the image on your PC. If you are working with graphics for any length of time or want to create an image for inclusion as an image in a document or web page using this piece of equipment will not allow you to do so.
Great shame as every other function works well - it cannot be beyond the wit of HP to include a Windows application that enables you to scan an image, receive it in the software you are using at the time (e.g. Outlook, Word, Photoshop...) and use it in your work.
HP Printers several years older than this £1000+ Enterprise printer were able to do this simple job and have done so for a great many years. Just being able to use Microsoft's Fax and Scan would be start.

Problem with installing and running some applications or drivers

When installing and installing some items, towards the end of the installation I get this message:
/System/Library/Extensions/comcy_driver_USBDevice.kext
*was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for update*
The end result is that some things do not seem to work properly, such as my HP printer. Would anybody have any ideas on how to fix this problem?

Thank you for your response. Originally, I had a problem with Airport and ended up reinstalling Snow Leopard. Since then, when downloading upgrades etc, such as HP printer drivers, iTunes etc., towards the end of the download when its running the script, I get this message: /System/Library/Extensions/comcy_driver_USBDevice.kext
+was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for update+
Sometimes, the download hangs and is unable to complete. The main problem I've encountered so far with an application is when I use the printer to scan an image via Preview, it's blank: there's nothing there.

Questions on Drivers & printing to networked Windows computer (CANON)

I'm trying to print over a network, to a CANON printer connected to a Windows PC.
My initial attempts resulted in the document being printed 75% smaller on the upper left corner of the page only. (Margins etc. are all fine).
Sounded to me like a driver problem, so I downloaded the latest driver for OS X(from CANON). I installed the driver, but now, when I try to setup a new printer, I still can't see my printer model (ip5000) in the available list. (The options are either Generic or one of the gimp drivers that came with OS X).
Where did it put the driver? - How can I make the printer use it?
And, how do you un-install a driver? (in case it doesn't work)
Thanks.

Hi there,
The drivers for the Canon PIXMA range of printers are not designed to work across a network, they are for direct USB connections. As has been mentioned numerous times in this forum, if you want to print to a Canon BJ printer that is networked, ex. shared by a Windows PC, you need to use the CUPS (GIMP) drivers that are included with the OS. The only exception to this is for the R series of the PIXMA printers, which have an Ethernet and wireless connection. There is a Canon network utility that redirects the spooled file to the remote printer.
Try using the S800 GIMP driver. You will have to open the driver properties and set it to Text to get good quality printing.
Better still, download the latest release of Gutenprint 5.0.0 and use the iP4000 driver. It works nicely to my iP5200R hanging off an XP SP2 box.
Regards,
Paul

How to uninstall print drivers Canon MF4150 issues

Hello all, I am having a nightmare of a time getting my Canon MF4150 to print. It looks from all of the threads on here it was a less than ideal choice for a Mac owner.
When I first bought the unit I managed to get it to print, everything seemed peachy.
Problems arose when I wanted to use the unit to scan. I downloaded a variety of third party software and drivers in an attempt to get the scan function working. I had mixed results, and this process seemed to upset the printing side of things. Once I scanned a document, the printer would then not work.
I abandoned the idea of scanning through the MF4150 and have gone back to dedicated Epson scanner.
Since then I have not had any luck getting the printer to print again.
I have gone through all the MF4150 related threads on these boards I can find, and followed the process to installed outlined here - https://discussions.apple.com/message/7657893#7657893 but to no avail.
I really just want this thing to print and it's driving me nuts.
I have the printer attached directly to my MacBook Pro running 10.5.2. I'm not trying to print through the Airport.
I would like to know how to completely uninstall any UFR II drivers and related software / information and start this process from the beginning again.
So far, using the answer provided by PAHU here https://discussions.apple.com/message/7657893#7657893
I have -
1. Open System Preferences > Print & Fax
> DONE
2. Select the MF4150 printer and press the minus " - " button to remove the printer. Do the same to any other printers that are in the printer list.
> DONE
3. Hold down the Control key and click in the empty printer list. A window showing 'Reset printing system' will display. Click this.
> DONE
4. Close the Print & Fax utility.
> DONE
5. Run the Canon UFR2 v1.70 installer and select Uninstall when the Easy Install menu appears
> This is where I get snagged. I'm not offered a Uninstall option. I have attached a screen grab of the window I am presented with. I am currently trying the "o1141enx_m_ufr224" version of the UFR driver. I have continued to complete the points below regardless of the fact i cannot uninstall.
6. Restart the Mac and run the v1.70 installer again to add the UFR2 files back onto your Mac
7. Go to Applications > Utilities and open Disk Utility. Select the Mac OS X partition in the left pane and select 'Repair Disk Permissions'. When this has completed, quit Disk Utility
8. Open Print & Fax and add the MF4270 again
9. Open TextEdit, type some simple text and select to print.
10. Report back if the above doesn't get you printing.
I have also attach a screen grab of the process I go through when adding the printer.
Any help with this would be amazing. I've tried everything I can think of.
My latest idea is to try and remove any trace of previous printer drivers and go from there. You can see in my list of available drivers in the file attached I now have all sorts of UFR drivers in the list.
Again, if anyone can throw me a line on this that would be great.
Thanks & Regards
Coz

Hello Coz,
It's been a while since you've posted, I hope you have not given up. I was having grief with my MF4150 as well, but got it working. There is a more current driver - search for Mac_UFRII_V230_uk_EN and install it.
Then, when you go to add your printer through System Preferences > Print & Fax, make sure you click the "default" icon in the top of the dialog. It should show your Canon MF 4100 series , then use the bottom drop down menu to choose your driver and select Canno MF410 Series UFRII LT (UK) from the list.
