RT-AC68U : wrt-Merlin 380.57: USB 3.0 Problem

[Amin]

Hello.
I update Asus RT-AC68U from 378.56_2 to 380.57 (Firmware Build Thu Dec 24 18:54:10 UTC 2015 merlin@795ca35) through `mtd-write2 file.trx linux && reboot`, make factory reset and restore my nvram and JFFS from nvram-save scripts.

All setting restored correctly, but i found 2 problems:
* NAT HW Acceleration stay off.
I try disable L7-DPI statistic, but this not help. When i try set option "NAT Acceleration" = "Auto" in Settings, LAN, Switch Control, i see applying progress, but option stay
in off. In 378.56_2 this option has 'Auto' value.
* My USB 3.0 Flash (San Disk UltraFit 64 Gb) not working in USB 3.0 port.
When i insert USB3-Flash in USB 2.0-port, device mounted correctly.
When i try old USB-2.0-flash (4Gb) in USB 3.0 port - also work correct.
But USB-3.0 Flash don't work in USB 3.0 port, i even don't info in `lsusb`

Only one tricks can help - insert in USB 3.0 Port old 4Gb-USB2.0-Flash, mount,
unmount, and insert USB-3.0-Flash. But this work only until reboot.
After reboot USB 3.0 Flash don't mount automatically if inserted in USB 3.0 port.
Same USB-3.0-64Gb Flash, inserted in USB 2.0 port, mounted correctly after reboot.

I ready to downgrade firmware, but more interest solve this issue.

I had the same USB3.0 issue on this version, downgrade to 378.56-2 no problem. Sandisk 32GB thumb drive.

Going back through the threads, it appears that SanDisk drives are implicated as in at least one other case, changing the make of drive cured the problem

rickysuper, a has only 378.56-2 release, not 380.56-2 Does it misprint 380.56 or 380.56 really released ?
CoIH, i don't understand what i must make with my usb-flash. In my PC's and in 378.56 release this flash work corrctly.

Nowtime i encountered some problems with 380.57 (this USB3.0 issue and some wifi unstability) and make downgrade to 378.56-2. Downgrade to 378.56-2 solve all my problems.

If need, i can collect some data about my flash if this help solve problems in newest release versions.
