USB auto mount - specific versus general driver

USB auto mount - specific versus general driver

[Robert Mykland]

Folks,

Consider a USB key that auto mounts as a generic USB storage device 
using the block level driver for that.  Can I write a driver that, for 
example, is more specific to that key and gets loaded and used at auto 
mount time instead of the generic driver?  How would I go about 
identifying my driver so it superseded the generic one?

Thanks in Advance,

-- Robert.

You'd have to add an unusual device entry to the USB storage driver 
which tells it not to claim that device. Look at 
drivers/usb/storage/unusual_devs.h and the US_FL_IGNORE_DEVICE flag.
