This is a specific request for legacy drivers. The (often part of the HCL MiLeap or older Busybee series) is quite old, and Windows 7 32-bit was its native operating system.

However, HCL no longer hosts drivers for these models on their official website. To get this working, here is the most you actually need: An offline driver scanner/installer for legacy hardware.

Since you cannot find these drivers by searching manually, here is the practical solution to build that feature yourself: Instead of searching for "HCL LTC 02102 driver," you need a tool that scans the Hardware IDs (VEN_&DEV_ codes) and matches them to generic Microsoft or OEM drivers.
