Hi, welcome to video tutorial form Robojax. In this video I'm going to show
you how we can resolve this Prolific USB-to-Serial device. This is a device
you might have a different device but the chip inside it is the same Prolific
that you have issue with. So this method that I show here will work with Windows 8.1
and Windows 10 tested. The driver you should not have an issue with
Windows 7 and prior Windows so let me just disconnect it so you can see this
is the screen that I have. So the first thing open the device manager. Right
click here at the Start menu and then select Device Manager at Windows 10 and
Windows 8.1 you will see this option so we open the device manager and we go to
that device if you're using other windows click here and then type run and
when when run opens then type the devmgmt.msc
and press OK . This will open your device manager
the first solution is that you right click here and then update the driver
and then select Browse my Computer and then in this screen select this option
you will have multiple options here. Multiple options which I'm gonna show
you next. If you don't have it if you're at this situation then we will go to
that driver and we will download the driver so the link bit.ly/prolific333
that refers to driver version 3.3.3 now I've put it this link
will download the file from robojax.com come from our own website so let me just
copy it and then paste it (CTRL+V)
so once the pop up come just save it. I've saved in in my computer so wherever you
saved it just go there if you are using Chrome just click here show and folder
and this is a driver this is a zip so I have 7-zip .
If you don't have 7-zip you can get it from www.7zip.org or use other software I'm just select
Extract Here. So now we will have this option just file so so now let's run
this .exe I have tested and run it with my antivirus it's clean ok
not treat. nothing found so it has been tested so this option will uninstall you
see this the job of this one is to uninstall any prior drivers select and
accept it and finish. Now nothing has happened there so the problem is there
so this time run it again for the second time. Now go and finish. Now this will
change some stuff so let me remove this and then plug it in. In some cases you
will see the issue will be resolved because you you might have tried and
unsolved multiple type of drivers but in this case we see the issue has not be
resolved. Click update the driver and then Browse my computer and software and
the screen select the bottom one. Now you will see you will see 3.3.3
3.8.18 select the first one which is from
2009 the 2017 is not compatible. Select this option click Next and it says
successfully resolved and the issue is resolved and it will work fine. In case
if you don't see that 3.3 and two options just after removing the
driver make sure to reboot your computer. I hope this resolved the issue. Thank you
