Review of Linux Compatibility

The LogiLink WL0084A shoud not be mixed up with the version WL0084B because both versions use the different chipsets. Fortunately, both sticks can be distunguised due to their different housings (the WL0084B stick is longer than the WL0084A).

There are two revisions of the WL0084A. Both use the Realtek rtl8188cus chipset. The version 1 has thee USB ID 0bda:8176

and is supported by the kernel module rtl8192cu. Additionally, the stick needs a firmware file that can be installed under Ubuntu by

sudo apt-get install linux-firmware-nonfree

Without the firmware file the loading of the driver will produce the following error message:

rtl8192cu 1-1.2:1.0: usb_probe_interface
rtl8192cu 1-1.2:1.0: usb_probe_interface - got id

The version 10 of the WL0084A has the USB ID 0bda:8179

Bus 001 Device 010: ID 0bda:8179 Realtek Semiconductor Corp.

Both versions can be distinguised by the model number. which is printed on the packaging.

A installation instruction for revision 10 can be found at ubuntuusers.de (in german).
