Hi,

I am writing a usb device driver that is loaded as a module into the kernel.
My question is who allocates the major and minor numbers for my device
driver (it's for a smartcard reader)? I saw in the device list that there
are allocated major number for other usb devices, but not for the type I
need.

Also, I understood that there is a way to communicate with the kernel driver
from a user mode application without using the mknod command to create the
link to the driver. I would be grateful if someone could explain how to use
it and how to open a communication channel with the driver if this dynamic
way is used.

Thanks in advance,
Amira.
