[SOLVED] USB devices are recognized but not accessible

EDIT: i updated my packages and rebooted and the problem does not exist anymore. leaving this post up incase someone else has the same problem. just reboot.

Hey. I installed Arch on this laptop (80L0 Lenovo G50-80 according to neofetch) a few days ago, following the installation guide. The built-in input devices all work fine,  but my issue is that USB devices don't seem to work. I've tried plugging in a Logitech wireless mouse, Wacom Intuos tablet, and various USB storage devices. dmesg recognizes me plugging and unplugging the devices, but input doesn't work and none of the devices show up in /proc/bus/input/devices.

Output of dmesg when I plug and unplug my Logitech wireless mouse and Wacom tablet:

[277377.654002] usb 1-1: new full-speed USB device number 18 using xhci_hcd
[277377.796515] usb 1-1: New USB device found, idVendor=046d, idProduct=c52b, bcdDevice=12.11
[277377.796522] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[277377.796525] usb 1-1: Product: USB Receiver
[277377.796527] usb 1-1: Manufacturer: Logitech
[277379.913830] usb 1-1: USB disconnect, device number 18
[277388.597361] usb 1-1: new full-speed USB device number 19 using xhci_hcd
[277388.739175] usb 1-1: New USB device found, idVendor=056a, idProduct=0374, bcdDevice= 1.07
[277388.739190] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[277388.739196] usb 1-1: Product: Intuos S
[277388.739200] usb 1-1: Manufacturer: Wacom Co.,Ltd.
[277388.739204] usb 1-1: SerialNumber: 8BH00R2058863
[277392.103663] usb 1-1: USB disconnect, device number 19

lsusb also recognizes the devices:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 8087:07dc Intel Corp. Bluetooth wireless interface
Bus 001 Device 003: ID 5986:014f Acer, Inc Lenovo EasyCamera
Bus 001 Device 002: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
Bus 001 Device 021: ID 056a:0374 Wacom Co., Ltd CTL-4100 [Intuos (S)]
Bus 001 Device 020: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

But the devices are not listed in /proc/bus/input/devices:

$ grep -i 'wacom' /proc/bus/input/devices
$ grep -i 'logitech' /proc/bus/input/devices

I read the wiki page on Wacom tablets and xf86-input-wacom IS installed.

When I plug in any USB storage device, dmesg reports the connection but the output of lsblk remains the same. No clue what's causing this.
