Looking at the current(?) vendor driver
4309c61f45497de0241781a507df53e4 *RTL8192CU_linux_v3.0.2164.20110715.zip
there appear to be several more USB IDs which might be worth adding; so
far I only submitted a patch for a tested USB ID.

I've dropped IDs already present in rtl8192cu, the two lines starting 
with '!' appear to be typos in either of the drivers:

#ifdef CONFIG_RTL8192C
        /*=== Realtek demoboard ===*/

        /****** 8188CUS ********/
        {USB_DEVICE(USB_VENDER_ID_REALTEK, 0x817F)},//8188RU

        /****** 8192CUS ********/
        {USB_DEVICE(USB_VENDER_ID_REALTEK, 0x8178)},//8192cu 2*2
        {USB_DEVICE(USB_VENDER_ID_REALTEK, 0x8186)},//8192CE-VAU USB minCard

        /*=== Customer ID ===*/
        /****** 8188CUS Dongle ********/
        {USB_DEVICE(0x4855, 0x0090)},// - Feixun
        {USB_DEVICE(0x13D3, 0x3357)},// - AzureWave
        {USB_DEVICE(0x0DF6, 0x005C)},//Sitecom - Edimax
        {USB_DEVICE(0x0BDA, 0x5088)},//Thinkware - CC&C
        {USB_DEVICE(0x4856, 0x0091)},//NetweeN - Feixun
        {USB_DEVICE(0x9846, 0x9041)},//Netgear - Cameo
        {USB_DEVICE(0x2019, 0x4902)},//Planex - Etop
        {USB_DEVICE(0x2019, 0xAB2E)},//SW-WF02-AD15 -Abocom

        /****** 8188CE-VAU ********/
!       {USB_DEVICE(0x13D3, 0x3359)},// - Azwave
!       {USB_DEVICE(0x13D3, 0x3358)},// - Azwave

        /****** 8188CUS Slim Solo********/
        {USB_DEVICE(0x04F2, 0xAFF7)},//XAVI - XAVI
        {USB_DEVICE(0x04F2, 0xAFF9)},//XAVI - XAVI
        {USB_DEVICE(0x04F2, 0xAFFA)},//XAVI - XAVI

        /****** 8188CUS Slim Combo ********/
        {USB_DEVICE(0x04F2, 0xAFF8)},//XAVI - XAVI
        {USB_DEVICE(0x04F2, 0xAFFB)},//XAVI - XAVI
        {USB_DEVICE(0x04F2, 0xAFFC)},//XAVI - XAVI
        {USB_DEVICE(0x2019, 0x1201)},//Planex - Vencer

        /****** 8192CUS Dongle ********/
        {USB_DEVICE(0x4855, 0x0091)},// - Feixun
        {USB_DEVICE(0x050D, 0x2102)},//Belkin - Sercomm
        {USB_DEVICE(0x050D, 0x2103)},//Belkin - Edimax
        {USB_DEVICE(0x20F4, 0x624D)},//TRENDnet
        {USB_DEVICE(0x0DF6, 0x0061)},//Sitecom - Edimax
        {USB_DEVICE(0x0B05, 0x17AB)},//ASUS - Edimax
#endif
        {}      /* Terminating entry */
};

While I can't confirm it myself, as I don't have any rtl8192cu hardware
locally, I've gotten feedback[1] that temporarily adding new IDs via

# modprobe rtl8192cu 
# echo -n "050d 2103" > /sys/bus/usb/drivers/rtl8192cu/new_id

appears not be successful and might Oops the kernel[2]. Given that I
can't test it myself and considering that the reporter's kernel is
tainted, I can't claim this for sure - but I could ask the original 
reporter to test it again.
