If you encountered any problems, set debug log use echo 5 > /proc/net/rtl88x2bu/log_level or modprobe 88x2bu rtw_drv_log_level=5, and post your dmesg and network managers logs to https://pastebin.com/ .

I'm getting build errors on the latest kernel (5.6.3-arch1-1):

Thank you, RinCat! I was at a loss 'til I found your package. Cheers, matthew

Updated to support Linux 5.6

does't help this issue, but while you are working on it, http://www.cudytech.com/wu1200_software_download contains 5.6.1.6

this is the only patch that I saw in it

@sylphid it could be fixed tomorrow if I get enough time.

It seems that this module is broken in kernels 5.6 and newer from this commit https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/diff/?id=d56c0d45f0e27f814e87a1676b6bdccccbc252e9

@cwaffles Since this is DKMS version, I don't plan add a specific kernel headers. DKMS users should have their kernels headers installed already.

Please add the kernel headers to the dependency list (pacman -S linux-headers)

@pokemod97 I can't confirm your device chip, 0bda:c811 is 8811CU ID, but the driver from the website is 88x2BU.

@RinCat I'm trying to use the Cudy WU650S http://www.cudytech.com/spqxz with your driver version on linux 5.4.5. However there is no indication it's working. $ dkms status
