WIFI with RTL8188EU for BeagleBone Black

Hello everyone.
I was buy TL-WN725N V2 wifi usb adapter with RTL8188EU chip for my BBB
I was found driver with patches for Kernel version 3.8+ and compile it. After driver installation wlan0 is up, but when I plug out Ethernet cable from BBB WiFi is disappear.
If I try to boot without Ethernet cable - WiFi not worked it even not trying to connect to WLAN but if I plug in Ethernet cable to BBB - WiFi come up and connect to WLAN.

Any ideas?
