Question [Q] Problem On USB OTG CM 11

I'm having a problem when accessing USB OTG,, my devices require external powered OTG which is work in previous ROM (CM 10.1) but after upgrading to CM 11 it wont detect any flash disk in the folder storage/usbdisk/

But soon after ejecting the flash disk i got notification in notification bar showing me that Removed SD card,,

I didnt get Preparing SD Card notification just like i used to get in my Previous ROM,,
is this a bug? how to fix it?
