[Solved] Unable to mount USB SDXC Reader

I have a usb SDXC reader that came with a 64gb microsd card I purchased from Gigastone.

I haven't been able to get the kernel to assign it a /dev/sdX

I looked at this thread here: https://bbs.archlinux.org/viewtopic.php?pid=1308466 and waiting 5+ minutes doesnt seem to make it work, also it is fairly dated. Not sure if it even applies, but the dmesg output and symptoms seemed to be similar

$ dmesg | tail
[ 9789.406256] usb 2-1.1: new high-speed USB device number 5 using ehci-pci

$ uname -a
Linux null 3.18.1-3-ck #1 SMP PREEMPT Mon Dec 22 14:29:22 EST 2014 x86_64 GNU/Linux

is there anything I can do to troubleshoot this or is this outside of my control?

after a restart, things have started working of course.
