Hi, I recently bought a K8055 board but it doesn’t work properly under windows 7x64.
When I plug it in the USB the board will not be recognized. this goes on for about 4 to 20 times (or more) before windows recognizes the board. then when I restart the computer the problem stars all over again.
I’ve installed the 3.0 version drivers into system32, but that doesn’t work.
Does someone have a solution?
Regards Jorim
There seems to be a problem with the Windows driver to detect the hardware.
[quote]I’ve installed the 3.0 version drivers into system32, but that doesn’t work.[/quote]In 64-bit environment the K8055D.DLL must be copied to \Windows\SysWOW64 folder.
If you get the PC to detect the hardware then you may download this latest K8055 software package with the new K8055D.DLL version 4.0:

Thanks for your reply. I’ve installed the new .dll version on my computer in the correct folder. It works slightly better now. It’s now 1 out of 3 to 6 times that it will be recognized.

I know. But unfortunately there isn’t a solution for it yet 
Do you have any other options than could work?
Hi,
Have you tried it on a different machine?
Maybe a friends machine.
This will tell you if your machine is having a problem or there is a problem with the K8055.
You might want to try a different USB cable.
Do you have a lot of other USB devices plugged into your machine maybe remove some of them.
Just a thought
I’ve got a brand new cable for it. And the usb ports should be powerful enough to provide the power.
I’ve tried it on a 32bit XP computer. No problems there.
Windows 7 32Bit, Won’t work. So i think it has something tot do with windows 7. but i can’t figure out what
Do you get the same indications on the Win 7 32 bit machine that you get on the 64 bit machine?
Yes. “USB device not recognized”(translated from dutch). that does on for about 6 to 10 times. Then it suddenly knows what it is…mmmm Windows 7 with Alzheimer disease? 
Anyone?
