Problem with Sierra Wireless AC775 on PCIxx12 Cardbus Controller

[Marc F. Clemente]

Edouard,

Do you have the appropriate cis file in /lib/firmware?
Download this file and untar it.
http://www.sierrawireless.com/software/7x0/AirCard_7xx_Linux.tar.gz

Look at this page.  http://www.lea-linux.org/cached/index/AC775.html
Sierra's page is a bit outdated.  You should do:
cp SW_7xx_SER.dat /lib/firmware/SW_7xx_SER.cis

Then insert the card.  It should create a /dev/ttyS0 file.

Now that I have the device file, I still can't get it to work though.  I 
open minicom, and try to do "atz" but the modem never answers.  Please 
let me know if you get it working.

Thanks,

Marc
