I am looking for a Windows 7 x64 driver for a cheap USB to 9pin serial cable. It's one of the blue cables with a CH340 UART chip. I've found the drivers for XP and they work just fine but I really need the Windows 7 x64 drivers.

The hardware id is: USB VID_1A86&PID_7523&REV_0254 When I use the XP drivers, Windows 7 complains that the drivers are unsigned and will not load the drivers. Even if I trick W7 to allow unsigned drivers - no go. I even disabled UAC and used a utility that signs the CH340 files - no go. Of course there is a Prolific 2203 chip that works with Windows 7 but I don't have that one. I even tried THAT driver - no go. Any one out there who has gotten this to work? It's for a Cisco 9 pin console cable and no serial port on the sucky Asus notebook with Windows 7 x64 on it.

The really odd thing is it works on the SAME Asus notebook running Vmware 7 with an XP guest. Thanks in advance, Nb.
