[Bluez-devel] FW: Regarding USB Bluetooth Driver for Linux.....(2.4.22 kernel)!

Hi,
 
I have a USB Bluetooth device which can be used to transfer/receive
files from my Mobile. 
 
I am working on a PBX system which is running on Linux.
I am planning to write a USB Bluetooth Driver for this in Linux. My  PBX
Linux kernel version is - 2.4.22-ncgl-10.12.1.0
(Note: This kernel is a modified kernel of "2.4.22" without bluetooth
support)
I dont have any means of re-compiling the whole kernel again and putting
it on the box.
Also its not possible for me to upgrade the kernel version to 2.6.
Also this system doesnt have the kernel source as well.
I have to compile my code in some other system and put my binaries on
this box to test.
 
 
I have written the starting part of it and my driver seems to detect the
device. That is I could able to read the interface and the endpoints
from it.
 
But I am stuck on the part where we need to do "register", "open",
"send" on the HCI device.
 
When I use HCI calls and install my driver I get "un-resolved" symbols.
(hci_register_dev, hci_unregister_dev)
I think this symbols are not exported in my kernel. 
Is there any way to EXPORT this symbols without re-building the Kernel
again?
 
Or is there any other way by which I can go ahead. That is without using
HCI.
Can I use RFCOMM here?? 
 
According to me it looks like "hci_core", "l2cap" and "rfcomm"
interfaces are missing from my kernel.
Is there a way to re-compile only this part from the whole kernel source
and install it on my system to get those symbols. 
 
 
Can you guide me writing my own simple USB bluetooth driver for kernel
2.4.22 where I can able to transfer files from my mobile to my linux pc.
Please help me  out.
 
 
 
Thanks, Regards
Pintu

we don't support the 2.4 kernel series anymore. So you are own your own.

Actually that is illegal.
