I have the 5 Espruino Pico boards,
I developed the program on windows 10 and upload the to board flash.
The problem is when i try connect the boards to windows 7 Embedded (I knows is old....) the board not found the driver on the windows.
i am try istall the drivers: stm32_vcp_1.3.1,stm32_vcp_1.4.0, en.stsw-stm32102
but in the device manager he is changed the the device to com port and show error : "A service installatin section in this INF is invalid".
and error in the event viewer about microsoft.windows.common
I am try this in windows 7 64 bit and is worked.
