-
Driver Signing and Security Policies
Modern operating systems enforce driver signing policies to enhance system security. These policies mandate that drivers be digitally signed by a trusted authority, thereby verifying their integrity and authenticity. Different operating system versions implement varying levels of driver signing requirements. Software that does not meet these signing requirements will be blocked from loading, preventing the associated I2C HID device from functioning. For instance, Windows enforces strict driver signing policies. If it lacks a valid digital signature or is signed with an outdated or untrusted certificate, the operating system will refuse to load the driver. A stylus will fail to provide pressure sensitivity if it is not validated. Thus, operating system updates can require driver software be recertified and resigned.
-
32-bit vs. 64-bit Architecture
An operating system’s bit architecture significantly affects driver compatibility. 32-bit operating systems can only utilize 32-bit drivers, while 64-bit operating systems are generally capable of running both 32-bit and 64-bit drivers (although 64-bit drivers are preferable for performance and security reasons). Attempting to install a driver with the wrong architecture will result in an error. This prevents the I2C HID device from being recognized and used by the system. Trying to load a 32-bit touchscreen driver on a 64-bit operating system can cause unexpected behavior. Thus, identifying the bit architecture of the operating system and selecting the corresponding architecture is essential.
In summation, the operating system version directly impacts the process of locating and installing I2C HID software.
