Sorry about the C++ style comments, I meant to fix it, but forgot about
it in the end.

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.

I have now asked the reporter to check the state of rtl8192cu again,
current state is (with a kernel including my original patch):
- functionality confirmed on an unencrypted network
- WPA2-psk not conclusively tested, it may be out of range for his device.
("EDIT: With my netbook I can get an IP address and use the neighbor's
   unsecured network. Also, the Belkin device reports it at -47 dBm
   signal strength, but my Toshiba netbook gives it -80 to -83 (which
   may explain why the Belkin couldn't get an IP address), so there are
   still some issues to sort.")
- no Oops if his USB ID is compiled into the module, that only happens
   if he tries to inject it into an unpatched kernel with:
   echo -n "050d 2103">   /sys/bus/usb/drivers/rtl8192cu/new_id
   (and I'm reluctant to raise this as potential issue completely, due
   to the tainted kernel condition on his system).

Hopefully he'll answer my further inquiries about the stability of his
Belkin n300 Micro USB soon.

I think that ID and 050d:2102 should be added to the kernel. AFAIK, all RTL8192CU and all RTL8188CU chips are alike, at least as far as the programming is concerned. At least if the device works with the new IDs, it likely works as well as any other device. There are some reports of low performance from some models, but none of them crash Linux. In addition, there is no diagnostic info that would allow the debugging of the problem. My specific device does not show this problem.

As you have seen, I sent the patch for the others.
