Wireless adapter RTL8187 initialization failed

I have a RTL81817 chipset in my USB wireless network adapter. I installed the driver, but it still didn’t work.

In Yast->Hardware->Hardware Information->USB the following details are displayed:

-Bus: USB
-Class(spec): unclassified device

When I type the command

 dmesg | grep firmware 

I get the following lines:

and when I type

dmesg | grep rtl8187L

I get the following lines:

What is the error here? Is it something that I haven’t installed or is it another problem?

Maybe this thread will help you out. It looks like they resolved their issue.
