I'm a software developer and I would like to make an application like FocusPal using Visual Basic and ASCOM driver. The idea is to add some functionaliy that FocusPal lacks, as define keys to move the motor or change the speed with the keyboard, save positions of focus for different types of cameras, etc. The software may be free and available to users.

My problem is that the ASCOM driver is quite poor and many properties/methods of the "Focuser object" do not work.
The question:
Could you provide me the necessary libraries or documentation of "ShoestringFCUSB_DLL.dll" that uses FocusPal?
Regards
