hi guy it's very easy
for tricks of USB devices
here are the instructions::
Go to registry editor:
Start, Run, type "regedit"
Find the following key: HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ StorageDevicePolicies
Create a REG_DWORD value named WriteProtect and give it the value 0.
and if you want to protect it you have to put 1 instead 1
