Yes, you can connect USB devices to ffp or (chrooted?) Debian, *if* there is kernel support for that specific device. When the kernel supports that device, you only need a device node in /dev (or any other place) to use it from userland. And it doesn't matter which userland, firmware, ffp or debian.
You can see if a device has kernel support by executing:

dmesg -c  # clear kernel log buffer
# insert USB device and wat 10 seconds
dmesg

Now you have all kernel logs regarding this device. When the kernel has recognized you should see the device name, and/or a generic name for the type of device.

usb 1-1: new full speed USB device using ehci_marvell and address 4
usb 1-1: configuration #1 chosen from 1 choice
Initializing USB Mass Storage driver...
usbcore: registered new interface driver usb-storage
USB Mass Storage support registered.

Thats what I get after waiting 10 secs.
So it recognises that I connect my USB device right?

But in my Ubutnu Laptop it makes a new file called ttyACM0 in /dev after connecting, but in my NAS, there is no new file after connecting.

Well, yes and no. According to the ttyACM0 I suppose it's some kind of modem, right? But it's recognized as a mass-storage device. And a strange one, as it doesn't detect any partitions.

I *think* this is a multimode device, which can provide it's driver (Windows only, I suppose) while being an USB stick, and then switch to 'modem mode'.
Have a look at usb_modeswitch.

BTW, when you switch the mode, another USB device should be detected, but that doesn't automatically mean that the devicenode in /dev is made. Therefore udev is needed, and udev also needs the right scripts. Don't know if that's available on your NAS. But you can just copy the devicenode from your laptop.

It also works with Ubuntu, because FHEM is a perl based programm and most used on Linux.
And the CUL is made for FHEM and it's an USB device which sends signals over 868,35 MHZ.
I use it for home automation.

Oh, ok.

I'll try the USB modeswitch now, I hope it helps.

But why does it works with Ubuntu but not with Debian, or does it work with my Laptop but not with the NAS?
I think, I'll also try running Debian in a VM and try the USB device there.

Then I know, if it's a hardware problem or a software problem.


/Edit:
One question, which of the following things do I need?
Because for every architectur there is another Version.

amd64         
armel
i386
ia64
kfreebsd-amd64
kfreebsd-i386
mips
mipsel
powerpc
s390
sparc

Thanks a lot
I'll try it later

Without your help, I had no chance to get it working, but with your help it might work
THANKS
