Hello forum!
I own a Ubiquiti EdgeRouter 6P onto which I would like to install OpenWrt Snapshot, following the guide in the respective commit message.
Following the guide, I managed to successfully execute
usb start
fatload usb 0:1 0x20000000 openwrt-octeon-ubnt_edgerouter-6p-initramfs-kernel.bin
bootoctlinux 0 numcores=4 endbootargs mem=0
on the Ubiquiti system. The router rebooted itself and I was greeted by OpenWrt. So far so good.
The subsequent step was to mount the USB drive again:
mkdir /tmp/sda
mount /dev/sda1 /tmp/sda
But this time, I received an error:
root@OpenWrt:/# mount /dev/sda1 /tmp/sda
[ 2077.629178] /dev/sda1: Can't open blockdev
[ 2077.633953] /dev/sda1: Can't open blockdev
mount: mounting /dev/sda1 on /tmp/sda failed: No such file or directory
I configured internet access as a client in my existing network:
uci set network.lan.proto="dhcp"
uci commit network
/etc/init.d/network restart
and blindly installed a bunch of USB packages following https://openwrt.org/docs/guide-user/storage/usb-drives-quickstart:
opkg update
opkg install block-mount e2fsprogs kmod-fs-ext4 kmod-usb-storage kmod-usb2 kmod-usb3
But alas! There is no USB functionality at all 
:
root@OpenWrt:/# ls -al /dev/sd*
ls: /dev/sd*: No such file or directory
root@OpenWrt:/# lsusb
unable to initialize libusb: -99
Unfortunately, I am at my wits end how to proceed. If anyone is able to help, I would greatly appreciate that 
By the way, this is my first post (so, "hello!"), but likely not my last, as I have just moved into a new home which I plan to fill with a number of OpenWrt-powered network devices. The router is just the first step 
Cheers, HP
