FS#2002 - WDR4300 lost USB storage


After a fresh install on a WDR4300, I decided to set up the extroot overlay.
After heavy IO usage (vsftpd copy to PC) the usb storage just got disappeared and reconnected as a new device (sdb) later.
It’s such a pain, because none of luci or ssh connection works this case. (I can have a try without password and telnet, but the logs are there)
The flash device (Transcend 790K) is so reliable, has been working on the previous 1043 v1 and v2 installations for years (with overlay as well).

I had something similar before with both the 1043 devices before, when there was a better quality usb hub in place.
I assume, this device is not so stable when the flash device is a connected with an external (1043) or built-in (4300) usb hub.
I tried my other 790K device with a simple DD test to find out maybe the older drive is problematic, but the newer failed as well. The power consumption is maximum ~0.05Amps at heavy use (nothing). I will have a try with another Kingston drive tomorrow.
In the attached dmesg log the newer drive was in place used without the overlay function.
