Hello, I just started using a TEW811DRU Broadcom BCM4708 and end up using mini build v3.0-r30880. I wanted to us the usb file sharing option and I understood that my setup has no kernel modules loaded due to space limitation. The address https://wikidevi.com/wiki/WikiDevi:DD-WRT/Mounting_USB_drive_without_located_onboard_fs_modules shows how to load alternative them using the an usb drive, but when trying to download the precompiled fs module using http://home.karneval.cz/10102207/fs.gz I get no response, not found error.
Please if any other user has the files or can lead me where to download them please share.

I'm a newbie user and lack knowledge to compile my own.
Thanks

Use the build designated for your router.
Mini builds do not have USB file system support.

Thanks for your answer. I do am using the designated build for TEW811DRU, and sadly is a mini build. There are pages that mention the possibility of enabling usb file system support on mini builds like http://www.dd-wrt.com/wiki/index.php/Mounting_USB_drive_without_located_onboard_fs_modules but all pages direct me to download the fs drivers that are no longer available using http://home.karneval.cz/10102207/fs.gz.

Any user that have them please share.
Thanks

Forget about those modules, they were for another cpu architecture.

What is the size of the dd-wrt file you downloaded and flashed to your router?

The file I flashed is listed as 7.5MB on ftp://ftp.dd-wrt.com/betas/2016/11-14-2016-r30880/trendnet-811DRU/

A 7.5MB build contains USB drivers and filesystem drivers.
What is shown under the USB tab in the gui when you plug in your drive?

I formatted an usb drive using gparted using ext2. The drive is recognized but not mounted. I named one of the partitions jffs testing if it will mount after trying out with one ext2 only and one fat32 too.

Additionaly I get from dmesg:

Which file system drivers do you have under /lib/modules/{kernel_version}/fs ?

What does lsmod show when you have the usb flash stick connected?

There is no folder fs.
Result from lsmod on picture.

Obviously no file system drivers included so not much to do.
Modern linux kernels refuse to load drivers from a different kernel version and even the kernel config must be the same for the kernel and for the drivers.

8MB Flash on a router with an ARM cpu is like a bad joke..

Well, thank you LOM for your answers. I was hoping that even though the drivers where not on board, I could follow the gouryella's guide. Sadly I couldn't even try it due to server files pointed on script are expired or are not reachable any more.

All is not lost (completely). I'm in the same boat as you - a router that requires a mini build. A mini build with support with usb filesystem support, and yet no filesystem modules.

I was able to go back in time to version 28882 to get ext2 filesystem support. I will forever be at this version until a filesystem kernel module is included in a more modern build.

I even posted a request to get some kind of filesystem support into the builds because I wrote a small bash script to get my system running of a hybrid of the flash and a 32GB usb stick. This allowed me to have the services that only the big boys get to play with. SIP proxy, ad blocking, lighttpd, SNMP, TOR, ttraff, zabbix (client). I've also installed an updated oping to have a full vim installation (for ease of hacking).

So, again I beg the dev to squeeze in a RW filesystem kernel module. I would greatly appreciate it.

Thanks for the info CyclingAsia. I'm going to check out version 28882. Actually I don't give up yet, I was reading that you could build an install, not sure how easy it is, but my theory is to get a revision that has the usb support files already loaded and add them to latest revision. Of course size will be something to review, so my idea is to remove modules I don't really would make use for. At least that's my theory.

I experienced this as well on my Trendnet TEW-811DRU.

I had never been able to go past 28112 because the router would die on any version after that. I decided to try a recent version again and was happy that all was working as it should. Then I noticed YAMon3 wasn't working and my USB wasn't mounting. Nothing I tried worked, hence I ended up on this thread.

I decided to go back to 28112 where everything works including the USB. If you don't need the USB to work then the recent versions are fine as I was running 31791 for the last few days without issue.
