Realtek RTL8192CU Polling FW ready fail!! REG_MCUFWDL:0x00000006

[Jeff Chua]

Just trying out the PCi GW-USBExtreme USB Wireless adaptor. It's
detected as Realtek 2019:ed17 and I'm using the kernel rtl8192cu
module.

Here's the dmesg ... it seems having problem with the firmware
(rtl8192cufw.bin) ... (Polling FW ready fail!!
REG_MCUFWDL:0x00000006). I downloaded the firmware from
http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git

Not sure anyone got a chance to look into this. I could get the device
to work with RTL8192CU_linux_v3.0.1590.20110511.zip (just that
ifconfig wlan0 froze the whole system).

rtw driver version=v3.0.1590.20110511
CHIP TYPE: RTL8188C_8192C
MAC Address from efuse= 00:22:cf:43:d3:8b


Thanks,
Jeff

I have not yet had an opportunity to check on this. My recollection is that the 
error message from the firmware did not affect the operation of the chip, but I 
have not yet proved that.

I cannot vouch for the operation of any drivers downloaded from the Realtek web 
site. Many of them will not work with 64-bit systems.
