I have been holding a few new ID's that are in the vendor driver awaiting a 
test. These include the following:

+       {RTL_USB_DEVICE(USB_VENDER_ID_REALTEK, 0x817f, rtl92cu_hal_cfg)},
+       {RTL_USB_DEVICE(0x13d3, 0x3357, rtl92cu_hal_cfg)}, /* AzureWave */
+       {RTL_USB_DEVICE(0x13d3, 0x3358, rtl92cu_hal_cfg)}, /*Azwave 8188CE-VAU*/
-       {RTL_USB_DEVICE(0x3359, 0x13d3, rtl92cu_hal_cfg)},
+       {RTL_USB_DEVICE(0x13d3, 0x3359, rtl92cu_hal_cfg)},
+       {RTL_USB_DEVICE(0x4855, 0x0090, rtl92cu_hal_cfg)}, /* Feixun */
+       {RTL_USB_DEVICE(0x4855, 0x0091, rtl92cu_hal_cfg)}, /* NetweeN-Feixun */
+       {RTL_USB_DEVICE(0x9846, 0x9041, rtl92cu_hal_cfg)}, /* Netgear Cameo */
+       {RTL_USB_DEVICE(0x050d, 0x2102, rtl92cu_hal_cfg)}, /*Belkin-Sercomm*/
+       {RTL_USB_DEVICE(0x050d, 0x2103, rtl92cu_hal_cfg)}, /*Belkin-Edimax*/

The deleted entry has the vendor and product reversed. The first one in the list 
has been tested and works.

Based on your report, I will drop the 050d entries. If you get a confirmation 
that 050d,2103 works, then submit that patch.
