Mode sense to enable cache

[aley]

Hi I am working on developing a USB device driver on a Blackfin I want windows write cache to be enabled for my device by default regardless of how it's set up in the windows registry, I know I can set the caching mode page however as soon as I do that windows sends a mode select command back trying to disable the write cache, is there anyway to stop this and make windows enable write cache for my device.

Thanks in advance.

Every host the drive attaches to will need to run the code.
