The prime suspect here is the Pi's USB port or hub chip is not seeing the dongles since both of your devices failed to work.
My go-to method to see if the USB port is working is to watch dmesg: $ sudo dmesg -w Then plug whatever you need to observe in the port. If you see nothing, there goes your connection not working for whatever reason. If you have openwrt, you could watch the syslog on openwrt to see if the device is connecting to your router: # logread -f I found the "follow" or "watch" option of any logging facility to be extremely useful as a first-line defense mechanism to debug anything not showing up.
