HI,
I've just finished my application patched with your code... and it works fine !
I gonna patch evently the kernel itself in the futur but for now it is a smart
way to do it.
Thanks
Xavier

OK, it is an idea !
Do you know how to rmmod and insmod a driver from an application ?
You can do it with a system.
If useful attached the piece of code that I use.

Hi,
Everytime I insert a new USB key to my SL811 controler, the kernel
detects properly the key and affect a new interface :
/dev/sda1
/dev/sdb1
/dev/sdc1
If I reuse the same key Linux succeeds to see it and affect the same
previous interface (/dev/sdb for instance).
But how to use everytime the same interface /dev/sda, even if I remove
the key and insert a different one into the same slot ?
Is it a standard Linux behavior to lock a /dev/sdx interface for a
dedicated peripheral once detected ?

rmmod/insmod of the usb storage kernel module, every time insert a usbkey, to
avoid this.
