[SPI interface] USB is not detecting and Prints as Attach flash drive first! about ch376msc

Sorry for the late reply, is there something else connected to the SPI port or just the module? If the SPI port is shared with other devices too then INT pin is required.

After checking wires, one of them was corrupted. After getting it fixed and it worked well.
I think you should close this issue. I will verify on WEMOS Lolin32 too. Thanks.

Same problem here. The SPI port is not shared at my setup. The only connected device is CH376s. Tested with Arduino UNO and WEMOS Lolin32. The UART is working fine but SPI is not working on both. The light on the CH376s stays on when the USB is inserted and the LED on the memory itself blinks when inserted.
Here is a complete wireing setup:

Color	CH376s	Arduino UNO	Name
Yellow	D3	D10	SCS
Blue	D5	D13	SCK
Purple	D6	D11	SDI-MOSI
Pink	D7	D12	SDO-MISO
White	5v	5v	5v
Brown	3.3v	3.3v	3.3v
Orange	GND	GND	GND
Red	GND	GND	GND
Black	GND	GND	GND

Used your default example basicUsageSPI.
