Actually, i thought it would be rather common...

This device needs a firmware download at startup... it's not just a
firmware update, it is is part of the 'boot' process.
The only issue i have at the moment is because I handle my firmware
download from userspace and the real action is ( and needs to be) in the
kernel. At the moment I haven't found an easy way to talk to my usb
driver (to indicate the firmware download process was successfull). Also
I cannot afford to have the firmware in the kernel module, it almost
300K binary data... madness to waste that much kernel memory.
