Hello,


I'm using emUSB Driver with embOS.
My application mount an MSD device to storage some files.
I'd like to know if is possible or there is any callback event the emUSB-Device provide when a disconnection occurs from USB.

Thank you!

Dear Yan,

I've tried to use the return after call the USBD_MSD_Task(), but I don't know why, sometimes the function don't return after disconnect the USB cable.


I think that some reason the function blocks.
I have some debug logs that prove it.

Have you ever seen this before?

Thanks.

Yan,

The log I mentioned is from my application.
It just print on a log.txt file saved on SD Card:

• "USB Connected" when run the task USBD_MSD_Task()
  
• "USB Disconnected" when the function USBD_MSD_Task() returns.
  

Sometimes the message "USB Disconnected" does not happens.

Is there some DEBUG flag that I'm able to show more useful messages for you?

Thanks.

Unfortunately I don't have those functions in my library.
The version that I'm working is:


This version is defined on USB.h file.

I'll do this next week I'll let you know if works and if the problem was solved.
By now, thanks for your support!
