Hello,

I write in english because i don't speak Chinese.

I wrote drivers for ch376 mass storage part. Anyway, i would like to plug others usb devices on the same CH376.

That is why i plugged an usb hub on ch376 usb port. Anyway, ch376 doest not detect the usb storage key now. How can i tell ch376 to find the default storage device on this usb hub ?

I would like to plug also a mouse on this ch376 hub and others usb devices. I don't understand clearly how to say to ch376 to switch to another node.

Does ch376 handles many usb devices connected to his usb port ?

Hi,CH376 can operate and access the full-speed USB HUB,and the communication with the downstream devices(must to be consistent with the HUB speed) of the HUB is realized through the operation of the HUB itself.
