I am using coldfire 54455 CPU and linux 2.6.25
Since ralink2800 usb is not included in 2.6.25, I imported the ralink2800usb from 2.6.31 distribution. Now either the usb dongle is not recognized (probe function is not triggered), or the driver crashed at lib/kref.c at kref_get function.
I do not know how to debug the problem. Can anyone give any suggestions?
Well upgrading your kernel to a 2.6.27 or higher kernel and use the compat-wireless package would do the trick much better then using a 2.6.31 module on a 2.6.25 kernel.
