CC1111 USB Dongle

I'm unable to detect the CC1111 usb stick with rf_modem code.

I have a CC1111 usb dongle that comes with the eZ430Chronos Watch. when I plug it in my linux box I get a ttyACM0 device. I soldered wires on the back according to the guide and tried to flash it with the rf_modem program for cc1111. Once I program the usb stick I'm unable to detect even a usb device on my linux machine I tried the same even on a windows machine but it failed to even detect any usb device.

When I reflash the usb stick with the orginal code that works with the watch , it works fine.

regards Noel

    Any luck figuring this out?

    I am stuck with the same problem with 64bit window 7, also tried it on 32bit window xp.

    also can you share the original code, or where can I find it.

    Thanks,

    Will

    The latest original code of the access point can be find under ez430 chronos wiki, or it comes with the cd.

    the problem with "rf_modem" code doesn't work with Access point could be because CC1111EMK's design is slightly different from the Access point; like their pin 3 and 4 are swapped, where one is led and other is data for USB.

    It's confirmed. By swapping the pin 3 and 4 of the cc1111 on the Access point, I am able to perform loopback with "rf_modem" code.
