I recently bought a laptop with Windows Vista 64. I have tried to
install uVision (mdk370.exe) along with ULINK various times with no
The last time I tried...
-The user account control (UAC) was disabled.
-I uninstalled removed uVision
-I uninstalled ULINK as described in "ULINK:REINSTALLING USB
DRIVER". I could only find the two files keilul.inf, keilul.sys and I
-I then restarted the computer.
-I installed uVision (mdk370.exe) - right click "Run as
-I installed the USB drivers (USBDrivers.exe, file version
22.214.171.124, product version 1.04) - right click "Run as
-I plugged ULINK into computer (other end of ULINK was already
plugged into MCB2140 board)
-I plugged MCB2140 board into computer
-vista detected both devices had been installed (the two
-the found new hardware box dialog appeared
-instead of working with that dialog, I opened up the device
manager (Control Panel--> Device Manager)
-the ULINK device appeared in ADMIN-PC-->Other
devices-->Unknown device. (I know this is the ULINK for two
reasons. First, this is the entry that appears/desappears when the
device is plugged in/unplugged. Second, the Hardware Ids is:
-I right clicked the unknown device (ULINK) and selected "Update
Driver Software" (while connected to the internet)
-I selected the automatic search
-the result: "Windows was unable to install your
Unknown Device", "Windows could not find driver software for your
-I then went back to the original "found new hardware" dialog box
that appeared immediately after installing the devices and selected
to find the software automatically. The result was the same.
The last time I used these devices (ULINK and MCB2140) on my
desktop (Windows XP), they both worked.
Does anyone have any idea what the problem may be? Thanks for your
