Once the cxacru-fw.bin file is in the adquate directory, and the modem is connected, the system log will report that a connection has been set up. Item 2.1: install the firmware and check whether it works Make sure that you name the firmware file cxacru-fw.binĬheck also UsbAdslModem/AccessRunner on this issue. After compiling cxacru-fw.c (the URL gives you clear instructions), cxacru-fw can extract the firmware from a file called Cn圎tU.sys on the modem CD, or the Windows partition. I have found a programm called cxacru-fw.c (I lost the URL name, the code is in Annex 1 at the end of this article). The sourceforge site gives you some intsructions. So you already have a legal copy of the firmware, the only problem is finding the firmware. If you have the modem working for Windows, the firmware is in the Windows partition. One of the files of this CD contains the firmware. The drivers in Ubuntu do not contain this firmware (otherwise it would be illegal), but you probably got a CD along with the modem. This small program (called firmware) is often licensed. The cxacru driver included in Ubuntu (since Ubuntu 6.x) will try to 'upload' a small program to the modem, allowing the microprocessor to do the 'modem-work'. Most USB modems contain a microprocessor (a 'simple' computer), which is programmable and therefore can do many different things, so it is sold a lot and can be cheap. This howto will help you to set up a e-tech V2 ADSL USB modem. This article does not follow the style standards in the Wiki Guide.
