Leica Usb Cable Driver For Windows 7 'LINK'
If all looks in order, I'd then try un-installing both of these drivers (serial/composite), selecting to remove the software. But then also check if you disconnect/reconnect, that an old serial driver is not recognised. If it is, remove that too using the same process. Do this for both boards and you'll be basically back to scratch. Probably worth a reboot to ensure windows is not holding anything, then try re-installing.
Leica Usb Cable Driver For Windows 7
We used this program on Windows XP and Windows 7. We also use it on Windows 10; however, there can be some problems with the serial port drivers. Unfortunately, it is not consistent and very much depends on the chipset used to make the Windows computer and the drivers that convert a USB port to a serial port. And, unfortunately, there seems to be little we can do to fix this. We recommend using a direct USB cable instead of a serial to USB converter. In the mean time, McPherron is finishing a new version of the EDM program in Python which is cross-platform compatible and can offer better support for serial communications. You can find it here.
