[OpenWrt-Devel] USB or SD card not mounted in Omega2+ router with LEDE iamge

[Arun Kumar]

Hi All,

I am facing an error where I can't find my USB or SD card and hence cant
upgrade to a new image.

SD Card or USB device plugged in would be usually automounted at
/tmp/mounts
But after sysupgrading to the latest LEDE image, the Omega2+ router detects
the USB device getting plugged in but doesnt display anywhere. Not even in
/dev/sdaX location.

When I plugin a USB device, I get this message:
[ 6382.201671] usb 1-1: new high-speed USB device number 3 using

Tried with both USB 1 and USB 2.0 devices. So tried to connect to Wifi and
download new image. But iwconfig is not working.

root at Omega-FB25:/# iwconfig
/bin/ash: iwconfig: not found

Note: This was working fine earlier and I did multiple image swaps between
my personal built ones and official images. I upgraded image from Omega2+
image to LEDE image[1].

Any suggestions on how to overcome this would be helpful.
