The DriverIdentifier is a tool that analyzes the system drivers on your computer. The utility reports if any new drivers are available, and provides the download files for the driver updates so you can install them quickly and easily.
Nuvoton Communications Port Driver Windows 7
The cable you are trying to use is a serial-to-USB converter. You would have to install a driver for such a device. The driver would then emulate a COM port, but these devices are notoriously hard to get working right because USB ports are inherently plug-and-play, but serial ports are not (they existed long before Windows).
If your computer actually has a real serial port on it, then that's the COM1 you're seeing, and of course the software wouldn't be able to use it because it isn't connected to that port. The driver for the device should be emulating a COM2 or something similar.
According to the K+DCAN USB Interface Driver Installation Manual once you install the drivers on the PC you should then find a new Virtual Comport which you will need to open the Advanced properties on within Device Manager and configure accordingly from there as per those steps or whatever you can get to work if this isn't the specific cable you have. This is the same area you can specify the COM port to use as well once you free up COM1 per the previous steps, you can then assign this one to COM1.
Starting in Windows 10, Usbser.inf was added to the %Systemroot%\INF directory, which loads Usbser.sys as the functional device object (FDO) in the device stack. If your device belongs to the communications and CDC control device class, Usbser.sys is loaded automatically. You do not need to write your own INF to reference the driver. The driver is loaded based on a compatible ID match similar to other USB device class drivers included in Windows.

Installed Windows 7 (64-bit) onto an HP Z240. The Display driver I'm using right now is the Standard VGA Adapter, and I'm sure there's a different set of drivers I could be using. For the Drivers page on HP, I download the video drivers and when I try to update through Device Manager, it says that the drivers do not support the OS.
The cpufreq core is not aware of the big.LITTLE architecture, so the driverdoes a good bit of work, Poirier said, but the code for making theswitching decision is simple. If the requested frequency can't besupported by the current processor, switch to the other. That part iseight lines of code, he said.
For example, if virtual CPU 0 is running on the A7 at 200MHz and a requestcomes in to go to 1.2GHz, the driver recognizes that the A7 cannot supportthat. In that case, it decides to power down the A7 (which is called theoutbound processor) and power up the A15 (inbound). There is a synchronization process that happens as part of the transition sothat the inbound processor can use the existing cache.That process isdescribed in Poirier's slides[PDF], starting at slide 17. 2ff7e9595c
