Router Name: Main Router
Router Model: Linksys EA6900
Firmware Version: DD-WRT v3.0-r47893 std (12/19/21)
Kernel Version: Linux 4.4.294 #4753 SMP Sun Dec 19 08:10:52 +07 2021 armv7l

So I did a bit of searching and reading on this issue and it seems to be an issue that has been around for a long time (see links below)

I have 3 EA6900, two that are 1.1 version and one that is first gen 1 version. I use the gen one for experimenting before installing anything on my two 1.1

I have CFE 1.3.0.7 installed on all 3 EA6900s, but I did try rolling my version 1 router back to 1.0.2.1 CFE to see if that would make any dif and it did not.

The USB 3.0 port works fine on FreshTomato, Xvortex or Asus firmware. It is only on dd-wrt that it does not work.


Links to pages I read and used to try and fix:

Necro'ing this since I've been messing w/ my remaining EA6900 (setting up for a sis-in-law and was helping a coworker using my other one) and thought I'd do a quick USB3 test. I moved them to DD long ago (since the install thread references to Xwrt) and this post had a decent list of reference posts. Cool

Everything work fine these days (testing my Ventoy drive):

Samba works fine too - though its much slower (like 22 MB/s). :-/
