x64 driver for HL-340 usb > serial device

(01-12-2012, 05:31 AM)Mad Professor Wrote: I installed the HL-340 adapter on Win 7 64-bit last night.

Download this file (CH341SER.ZIP) http://wch.cn/download/list.asp?id=5
Don't use the CH341SER.EXE file or the INSTALL folder!

Unzip it. Make note of where you put it (of course).
Plug in the HL-340 adapter.
When it asks for a driver, point it to the CH341SER\DRIVER folder that you unzipped.
Wait a minute or two, it will load.

I used this adapter to connect to a Cisco Router via HyperTerminal (hacked from XP SP3) and it worked perfectly!

Now, if only I could get Procom to install in 64-bit...

Good luck all and have fun!!!! Comp1

I've tried this way with my cable CH340 but still got problem.

Here's my problem:

it really depends on the cross over chip inside your cable.
some are so old that they don't work on a 64bit system
please do not email me, please use the forum to request driver support.

please post the device id string of the cable i will then check to see what chipset is inside.

the very early cables as sold on ebay don't even work with vista but it really does depend on what cross over chip is inisde your cable.

plug the cable in then go in to device manager to find its device id string.

more on how to do that can be found here.

It said " Driver install success" but still got problem in device manager "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"...but thanks anyway:)...
