I can't thank you enough for this information. I finally got my Prolific cable working after trying drivers from the cable vendor, Prolific, & another generic set, neither of which worked. Thanks!!

The CH341 does not use a Prolific chipset, rather it has one of the clone chips, in other words counterfit chip. The new Prolific drivers have been modified so they won't work with the cheap counterfit chipsets. The Prolific drivers will only work with a true Prolific chip. It's been a pain in the butt, but you can't blame Prolific for trying to protect their products.

The ATEN device (GUC-232A) uses a true Prolific chip, but a different address, so the Prolific drivers won't work with the ATEN device either.

I've been waiting for someone to write a program that will find what devices are loaded on the PC and install the correct driver files. How hard could that be?

Right now, it appears that Serial devices are here to stay. Its' time to start putting a serial port back on these newer computers. Installing a USB to Serial Port Adapter is now the biggest challenged for the PC user today. Isn't that a ridiculous state of affairs?

It's very probably a false positive. As you can see all the major AVs do not report a problem. Consequently you should post the driver ;)

MX-MART responded with the following:

hi, did you get the che41ser.exe from the CD or our website link: www.mxmart.com/info/driver.htm

not sure how accurate is the virustotal.com; but we're confident the drivers are safe, hundreds and thousands have been sold and it's directly from the manufacturer.

It will be stupid for the manufacturer. But if you prefer, you can return it for refund. thks

Thanks for the update, Anonymous! I apologize for unknowingly posting a link to a file that contains possible malware, and I feel terrible. I have reached out to MX-MART and until I can solve this problem, I have removed the link. I highly recommend that folks purchase the IOGEAR GUC232 as it works flawlessly with Windows 7 x86 and x64.

Just an FYI...I got my IOGEAR GUC232 adapter yesterday, plugged it in and Windiws 7 64-bit installed the drivers automatically! I would highly recommend purchasing the IOGEAR adapter for anyone who can't get the Prolific adapter to work in Windows 7 64-bit.

thank you, I was so frustrating to trying to install it for at least 2hour, and i get here...it works now.
THANKS

A quick search on Google Product Search for IOGEAR GUC232A should give you a list of purchasing options. You could always try eBay as well.

Thanks for your comment!

As I mentioned already, your workaround is not working for my equipment (don't ask me why).

I'm living in the Netherlands (Europe). Do you have an internet adress where to buy this cable online? The link provide me with a shop whit a price of USD 29,95

Unfortunately, these drivers won't work with Windows 7 64-bit, as they are not signed. You can follow the instructions on the above comment as a workaround.

Just last week, I purchased an IOGEAR GUC232A USB-Serial adapter from B&H Photo for about $16 (including shipping). IOGEAR does have signed 64-bit drivers for Windows 7. To me, it was worth dropping $16 to find a device that has proper driver support.

I have the same problems "driver install fail...

2010-03-11T08:28:43.803-06:00

I have the same problems "driver install failure" with the CH341SER procedure. I use Windows 7 Ultimate (x64) build 7600. Next to that I tried the standard Prolific files. After using these program the driver is still not installed after I plugged in the cable. I don't understand what the exe file from Prolific is doing? Will the driver be installed on my system? If so, where can I find this?

The procedure as describes above is not functioning for me. Is there anything that can be done more to get it installed?

Thanks in advance!

2010-02-06T22:06:46.880-06:00

Hey Abe,

I had the same problem. I removed the Prolific driver by running the Prolific install program again. Then, I opened the Device Manager and plugged in the cable in each USB port. When the device appeared in the list with the "!" icon, I right clicked and selected uninstall. I did this for all four ports on my laptop (Acer 5610Z). Then I removed the cable and ran the install for the CH341SER. After that, I plugged the cable into the USB port and it worked.

I am running Windows 7 (Build 7600 64-bit) and I can not get my Prolific based USB-to-Serial cable to work. I always end up with the following Device Manager error: "This device is not configured correctly. (Code 1)".I also tried installing the ch341ser.zip file and that did not help because when ever I tried to manually update the driver by pointing to the folder created by ch341ser then the Device Manager states that the most current Prolific driver is already installed.
