br2684ctl Invalid argument


I try to configure a Speedtouch 330 ADSL modem on USB. I'm working in an embedded environment using OpenWrt distribution, with 2.6.19.2 kernel.

Here are the dmesg messages when I plugin the modem:
Code:
hub 2-0:1.0: USB hub found
hub 2-0:1.0: 2 ports detected
usbcore: registered new interface driver speedtch
speedtch 1-2:1.0: found stage 1 firmware speedtch-1.bin
speedtch 1-2:1.0: found stage 2 firmware speedtch-2.bin
ATM dev 0: ADSL line is synchronising
ATM dev 0: ADSL line is up (2560 kb/s down | 512 kb/s up)
Everything looks fine, but I can't get the br2684ctl to work:
Code:
root@OpenWrt:~# br2684ctl -b -c 0 -a 0.35
RFC1483/2684 bridge: Interface "nas0" could not be created, reason: File exists

RFC1483/2684 bridge: Communicating over ATM 0.0.35, encapsulation: LLC

RFC1483/2684 bridge: Could not configure interface:Invalid argument
With dmesg spiting:
Code:
usbcore: registered new interface driver speedtch
ATM dev 0: ADSL line is synchronising
br2684: br2684_create
br2684: registered netdev nas0
br2684_create: register_netdev failed
Everything I though was necessary I've compiled as modules:
Code:
root@OpenWrt:~# lsmod

Do you have any idea why I get the "Invalid argument" message from br2684ctl?

PS: the same line with the same modem works fine on my desktop PC.
