Hi Larry,
Thank you for the patches.
Unfortunately, no cigar:

<After kernel re-compile>
usb 8-1: new high-speed USB device number 2 using ehci_hcd
r8712u: module is from the staging directory, the quality is unknown,
 you have been warned.
r8712u: DriverVersion: v7_0.20100831
r8712u: register rtl8712_netdev_ops to netdev_ops
r8712u: USB_SPEED_HIGH with 4 endpoints
r8712u: Boot from EFUSE: Autoload OK
r8712u: CustomerID = 0x0000
r8712u: MAC Address from efuse = 00:1a:ef:25:2d:f9
r8712u: Loading firmware from "rtlwifi/rtl8712u.bin"
usbcore: registered new interface driver r8712u
r8712u: r8711_wx_set_enc: IW_ENCODE_RESTRICTED
usb 8-1: USB disconnect, device number 2


NOTE: I haven't seen any "Badfw size" message.
            I applied the patches, hope against hope.
            (maybe, as a side effect, it can fix my problem)
