This guide is how to compile dm9601 module for Centos/RHEL6 (2.6.32-279.9.1.el6)
I both usb lan from CDR king with chipset of Davicom (dm9601), unfortunately RHEL6/Centos 6 dont work as expected. what I did is.
1. check if my device recognize and some basic info
My device has this info 0fe6:9700
2. I modify the original dm9601.c and insert the code below
I use the dm9601.c code for kernel 2.6.32 and insert the code below
see the modify code below, you can copy and paste as dm9601.c
3. Compile the source code using make, create 'Makefile' copy and paste the code below
Source dm9601.c modified version
