My USB host application is working fine in Debug Mode but there is a problem in Int Flash Release mode.

Every time when I insert the USB stick I got this error:


Vendor Information:              Mass Storage Device
Product Identification: Flash Disk
Product Revision Level: 8.07
Error while opening partition (UNKNOWN ERROR !!!)
Device removed, starting device cleanup
--->Closing MFS
--->Uninstalling PM
--->Closing disk


After that I have to restart microcontroller to use USB again.


I've check my application, web_hvac and mfs_usb examples with freescale and kingston sticks so far.



Any ideas?
