Hello,

HID devices works in the same way, you need a device driver for the 
hardware that exposes a HID interface and you can manage that HID 
interface using native hid.dll or use an abstraction layer like libusb-1.0.

https://github.com/JoshyFun/VUSBRelayPascal

My code to manage HID USB relays uses hid.dll (32 & 64 bits) or 
libusb-1.0 (32 bits only tested) on Windows, and libusb-1.0 or 
libusb-0.1 in Linux.

Of course, functions on hid.dll and libusb are no the same, they work in 
different way, but the libusb-1.0 works the same way in both platforms.

Implementation of hid.dll, libusb, etc, in my code only have relevant 
functions used in USB relays, so they can not used as a complete 
implementation.

In the other hand, the hardware you are trying to manage is 10CE:EB93 ? 
If the answer is yes, that device is *not* HID compatible so you can not 
use hid.dll for native access, you must use WinUSB API set, or the 
libusb-1.0 abstraction layer.
