I am sorry, but kernel 5.17 support is not added yet! I have no time for test. You can patch the driver and recompile again.

cd rtl8188eu
wget https://raw.githubusercontent.com/ivanovborislav/document/main/patch/rtl8188EU_v5.13.3_kernel_5.17-rc5_support.patch
patch -p1 < rtl8188EU_v5.13.3_kernel_5.17-rc5_support.patch
sudo make uninstall
make clean
make
sudo make install

It works, thank you!

You are welcome!

Kernel 5.17 is now supported. NO patch required.
