The Prolific 2303 works perfectly fine in Linux Mint. Yet, for some reason, Prolific says that some of these chips have reached the end of life and won't be 'supported' under Windows 8. Prolific suggests that you purchase their updated chipset (PL2303HX Rev D):
So, what is different about the newer chips that they *can* be supported in Windows 8, while the older ones can't? What has changed in Windows 8 that makes this support different?
Here's the yellow triangle with exclamation point that you'll see:
And here is the "Code 10" error:
Fixing it: Some clever people have figured out workarounds for this issue.
Get this file: Profilic_Win8_x64_x86.zip (Google Drive link here.)
Extract the contents of this file somewhere and examine the contents:
Right click the .inf file, and select "Install".
I didn't notice that anything happened when I ran it. Probably because I've tried so many different drivers and installations; maybe it was already installed, I don't know.
Got back to the device manager and right click the Prolific USB to Serial comm port, and click "Update Driver Software".
In the resulting dialog, click "Browse my computer for driver software":
Select "Let me pick from a list of device drivers on my computer":
Select the Prolific driver version 3.3.2 from 2008:
Win.
If all went well, you'll no longer see the yellow triangle:

Thanks a lot for the solution!! It's really work!
ReplyDeleteThx !
ReplyDeleteSo thanks! This's perfect solution! It's really work!
ReplyDeleteWorked for me!
ReplyDeleteI first had to remove the original driver using:
pnputil -e
to spot the oemXX.inf that had Prolific in it
and remove it:
pnputil -f -d oemXX.inf
Thanks
Andy

ReplyDeleteThis is not working for me. When I get to the step where it says, .int click install. I do not have an install button to click. I am on Windows 8. Somebody help, please.
ReplyDeletefirst extract all files then right click on the .inf file now itwill show install option...
Delete@myscilyn -- RIGHT CLICK the .inf file. There isn't a button to click, there should be a menu option 'install' just as in the photo here. If you don't see the install option see this:

ReplyDeleteOutstanding, helpful post. Fixed the problem I was having on my new Win 8.1 x64 laptop using an old USB to serial converter cable. I can now export coordinates off my 14 year old Garmin eTrex Legend with serial interface directly to my laptop again. Looks like I can postpone upgrading to a USB-ready GPS unit for a while longer now.
ReplyDeleteMuchas gracias funciona a la perfección, Saludos

I have another fix via virtualization - the driver in this article caused BSODs for me on 8.1.
ReplyDeletehttp://blog.voltagex.org/2015/07/29/fixing-a-buggy-windows-driver-with-a-virtual-machine/
I've not had a BSOD yet in Windows 8, I doubt it is the driver, it is more likely your hardware.
DeleteThank you!
ReplyDeletethankz brull..
ReplyDeleteBrilliant - many thanks - can now use the energy monitor device. Same instructions works under Windows 10 too.
ReplyDeletethank you very much.. it really really help..
ReplyDeleteHello
ReplyDeleteI am in win 10pro, I use prolific usb to send morse via n1mm plus sofware, prolific was installed but it does not work very well, morse sound with a problem of weight, dit and dat sound with a timing problem, It is like a DTR and RTS delay problem...BTW it works fine in a old N1mm...N1MM team say...N1MM+ uses .Net and different Microsoft serial port support code than N1MM did. Some Prolific drivers introduce latency with the MS serial port code used in .Net but do not with MSCOMM32.OCX which the old version used. This is a deficiency in the *Prolific driver*, not in our code.
Any idea to resolve this puzzle...

ReplyDeleteso. . . they updated the driver to make the device unusable on win 8 and above?
ReplyDeleteYes. The new driver does not support the old hardware. However the old driver still supports the old hardware just fine. Linux supports old/new with no changes.

ReplyDeleteTHANK U VERY VERY VERY VERY VERY MUCH..................... Its really work
ReplyDeleteThank you for this excellent post. It almost worked for me. But, now when I plug in the USB to RS232 cable, after about 5 seconds, my cursor starts rehoming to the bottom left of my (Windows 8) screen. If I move my mouse quickly, it will move an inch or two, but then immediately jumps back to the lower-left corner, making the computer essentially unusable. If I unplug the USB, that fixes it, until I plug it back in. Any suggestions from anyone as to how to fix that?
ReplyDeleteThank you for posting this. It almost worked for me, but now I have a new problem. When I plug in the USB to RS232 cable, after about five seconds, my cursor starts homing to the lower left corner continuously. If I move my mouse quickly enough, I can move the cursor about an inch or two, but then it jumps back to the corner, making use of my (Windows 8) machine essentially impossible. (Unplugging fixes it, until I plug in again.) Please help me fix this.

ReplyDeletethks so much
ReplyDeleteI downloaded and install windows 10 creator update, But I did not like it. After installation Microsoft shows downgrade option early after upgrading to Windows 10 and remove it after one month. I recently upgrade my windows 8.1 Professional operating system to windows 10 Professional being getting a license from ODosta Store
ReplyDeleteBut I did not like its overall structure. I think Its not Windows 10, Its version should be windows 6 as it has many faults.
I tried to downgrade back to my existing win 8.1 os and I saw as Microsoft was giving me option to downgrade. I thought that I'll downgrade after two month But after two month when I tried again, Microsoft removed that option. Now what to do. I searched and found your post, Which is very helpful for me. Thanks for sharing these details here.
Nice blog and also very informative.. Thanks for sharing it.
