Make failure, but not sure if I need this fix in the first place?

I have a RTS5129. the SD reader works fine with FAT32 cards but not exFAT ones despite having exfat-utils, exfat-fuse, and udisks2 all present on the offending machine.

I don't get any error messages when inserting an SD card. just ones formatted to exFAT do not show up in lsblk, gparted, etc. Do I need this fix if I'm on 4.9 kernel, or if I can see FAT32 cards but not exFAT cards with the card reader?

~:/tmp# cd rts5139 ~:/tmp/rts5139# make make -C /lib/modules/4.9.0-9-amd64/build/ SUBDIRS=/tmp/rts5139 modules make[1]: *** /lib/modules/4.9.0-9-amd64/build/: No such file or directory. Stop. Makefile:46: recipe for target 'all' failed make: *** [all] Error 2 ~:/tmp/rts5139# make install cp rts5139.ko /lib/modules/4.9.0-9-amd64/kernel/drivers/scsi -f cp: cannot stat 'rts5139.ko': No such file or directory Makefile:49: recipe for target 'install' failed make: *** [install] Error 1

I a still very new to Linux. is there any way I can get a pre-compiled version?

Thank you
