How to cross compile for EW-7811un adapter

I probably did not include all the steps necessary, but this should get you started to a solution. How to get Edimax EW-7811un nano USB wifi dongle working. I purchased an Edimax EW-7811Un USB WiFi adapter after a number of suggestions that it is commonly supported by urtwn(4) on OpenBSD, but they seem to be shipping new V2 model which is still identified as Realtek, but has a new device ID of 0xb811 (instead of 0x7811). It looks like this device is RTL8188EU based (not RTL8188CU like the 7811Un), since the linux driver they offer for download is called rtl8188EUS, so you'd add URTWN_DEV_8188EU(EDIMAX, EW7811UNV2) Notice that the Version 2 Edimax EW-7811un 7932:b811 uses a different RealTek device RTL8188EU than the Version 1 Edimax EW-7811un USB Ids 7932:7811 specifies a RTL8192cu chipset device. You would have to recompile the driver source code for rtwn on the Raspbian Linux.
