I am having trouble with using the RTL8192CU 802.11n USB network chip. I have
verified that I have the correct firmware (the size is 16014 bytes and the MD5
signature matches the one posted in various forums as correct). The kernel
tries to load it, but after about 20 seconds, a message indicating that it was
not available appears in my kernel log. No other reason is given.
As the problem occurs on a x86-64-bit system, is there a problem with loading
firmware into the device on those systems? Or might I have a buggy network
device?

What else should I look for or do?
