Hello everyone! 

I am trying to execute a C code in Nios IDE to create a file in pen drive connected to Micron Nand flash via USB. 

After running the program, file system is succesfuly initialized, USB host stack is also created and initialized. 

 

Then I connect the pen drive and the message : 

"Device connected. Device speed is full speed (12 Mb/s)" will be displayed. 

Later an error : "USBH_DevDescRd: 3119, err = -4" appears. 

 

I think this means that the device description is not being read successfully. Why is this happening? how to eliminate this error? 

please help, any advice is welcome...
