+
+In a previous patch the call to ieee80211_register_hw was moved from the
+load firmware callback to the rtl_pci_probe only.
+rt8192cu also uses this callback. Currently it doesnt create a wlan%d device.
+Fill in the call to ieee80211_register_hw in rtl_usb_probe.

+Subject: [PATCH] rtl8192cu: Prevent Ooops under rtl92c_set_fw_rsvdpagepkt
+
+rtl92c_set_fw_rsvdpagepkt is used by rtl8192cu and its pci sibling rtl8192ce.
+rtl_cmd_send_packet crashes when called inside rtl8192cu because it works on
+memory allocated only by rtl8192ce.
+Fix the crash by calling a dummy function when used in rtl8192cu.
+Comparision with the realtek vendor driver makes me think, something is missing in
+the dummy function.
+Short test as WPA2 station show good results connected to an 802.11g basestation.
+Traffic stops after few MBytes as WPA2 station connected to an 802.11n basestation.
