Hello. I installed Chaos Calmer (15.05) by these manuals: one and two. But on ls /dev i don't see any usb. How i can use USB flash or camera?

I'm not found "Release Notes" for 15.05/ar71xx/mikrotik. USB are supported?

I installed its:

# opkg update
...
# opkg install kmod-usb-core
...
Configuring kmod-nls-base.
Configuring kmod-usb-core.
# opkg install kmod-usb2
...
Configuring kmod-usb2.

then get errors:

# insmod usb-core
Failed to find usb-core. Maybe it is a built in module ?
# insmod usb2
Failed to find usb2. Maybe it is a built in module ?

I found modules in new files /etc/modules-boot.d/20-usb-core and /etc/modules-boot.d/40-usb2. But get errors too:

# insmod usb-common
module is already loaded - usb-common
# insmod usbcore
failed to insert /lib/modules/3.18.20/usbcore.ko
# insmod ehci-hcd
failed to insert /lib/modules/3.18.20/ehci-hcd.ko
# insmod ehci-platform
failed to insert /lib/modules/3.18.20/ehci-platform.ko
# insmod ehci-orion
Failed to find ehci-orion. Maybe it is a built in module ?
# insmod ehci-atmel
Failed to find ehci-atmel. Maybe it is a built in module ?

you don't need insmod it manually, reboot after installation and those modules have to be loaded automatically
and those error you get cuz you forgot to insmod nls_base and nls_utf8 first smile

Stas, thank you very much! I install kmod-video-core and kmod-video-uvc, then plug my camera and reboot. After reboot i found /dev/video0 and see it in lsusb:
