The full dump from lsusb is a bit much for a commit message. All you need is the one line from lsusb with no switches set.

According to the Vendor driver, which the comment indicates as the source of part of your patch, this particular device belongs in the "Customer ID" section under 8188CU, not where you placed it. In addition, I like to keep the USB IDs in numerical order within each section. Accordingly, your new ID should be between 0846:9041 and 0bda:5088.

I am assuming that you have such a device. A statement that this change allows it to work should be in the commit message. If you have not tested, then you need to state that.
