Hey all... I've reached the point where I don't know where to go after this... Since there are so many logs I could post I'll leave then out unless they are short or if someone wants them. According to the Elan site the p423 works w/ Linux and the aircard. As the subject says, I am trying to get my Sierra aircard 860 to work on my desktop. It works on my laptop that is running the same kernel (2.6.16.13-4-default) with the same modification to drivers/serial-cs.c. So far all the searching, including Elan's site, has come up with is info on how to do it under the old system (pre-2.6.13) using cardmgr and I don't want to downgraded the kernel. The PCMCIA-PCI brige is seen by the kernel as dmesg shows: 01:0a.0 CardBus bridge: ENE Technology Inc CB1420 Cardbus Controller (rev 02) 01:0a.1 CardBus bridge: ENE Technology Inc CB1420 Cardbus Controller (rev 02) When I plug the aircard in /etc/log/messages says that a card has been inserted but it does not say it has been registered to a /dev/ttySx like it does on the laptop. When I do a dump_cis with the card in I get the info on the card, I even made sure that I added the correct memory address to /etc/pcmcia/config.opts. I've aliased the long pci:string to serial_cs and it seems to load the correct modules. /sys/class/pcmcia_socket/pcmcia_socket0/1 contains the info for the card. /etc/udev/rules.d contains 50-pcmcia.rules from the laptop and 10-local which contains: NAME="pcmcia/aircard_860" SYMLINK="modem" MODE="0666" SUBSYSTEM=="pcmcia_socket" SYSFS{prod_id2}=="AC860" which is also from the laptop... Any ideas would be deeply appreciated ---
