then compile it
0) suche whelche version des Kernel du hast:
z.b
>>uname -a
Linux qnap 3.4.6 #1 Thu Jun 12 01:29:28 CST 2014 armv5tel
1) download the right kernel source von readynas
2) extract it somewhere e.g. /usr/src/kernel/linux-2.6.xxxxx-arm/
3) find the right kernel config file for your Netgear-ServerRN102
4) copy it to the main kernel source directory /usr/src/kernel/linux-2.6.xxxxx-arm/ with name .config
5) cd /usr/src/kernel/linux-2.6.xxxxx-arm/
6) edit it; find line with cdc-acm; tell the compiler that cdc-acm has to be compiled as module (comment away cdc-acm =m)
7) execute "make oldconfig"

execute "make modules" ; this takes hours; if you are experienced with linux restrict it to cdc-acm
9) test the newly compiled module with "insmod /usr/src/kernel/linux-2.6.xxxxx-arm/drivers/usb/class/cdc-acm.ko"
10) share your newly compiled modules with other users.
if you are blocked somewhere, I can only help you if you give feedback to each step.
