Remove USB Mass Storage Cause Media Player Crash.

I modify the UMSS sample.But when I remove my USB device that is playing mpeg.
The media player sometimes causes system crash.
Need ur help,thx a lot.

i am sorry to say that i can\'t help you with this question. now i am reading UMSS. but i can\'t use it. could you help me?
i use a flash disk to test this sample code. i am sure that my flash disk is OK. i have modified the UMSS inf, and install it. but disk symbol is not appeared. i find that, in UMSSPDR_AerBootComplete, it does not find DCB. because it is removed in UMSSPDR_AerDeviceInquiry. it confuses me. if remove it in UMSSPDR_AerDeviceInquiry, UMSSPDR_AerBootComplete will return fail. but there is comment in UMSSPDR_AerDeviceInquiry. if i remove the delete call in UMSSPDR_AerDeviceInquiry, the disk symbol will not be appeared. why? could you help me?
thank you very much!
