Hardware :: USB Hub Only Recognizes One Input

I have used Ubuntu and Fedora and am familiar with Linux for about two years now. I have recently installed Arch Linux on one of my computers, and I like the distro so far. However, I am having an issue with my USB hub. When I connect a mouse and keyboard to the hub, the computer only recognizes input from the device that I plug in first when using a window manager (the keyboard always works when I am not in a window manager). If I disconnect one device, the other device starts working. Both devices appear in dmesg when I disconnect and reconnect them. So the computer is recognizing the devices independently, but input from one device is not received. I have tried this on both Gnome and Fluxbox, with the same result. If I plug both devices directly into the computer's USB ports, both devices work at the same time. The hub works on a Windows 7 system and on an Ubuntu system, so the hub is not faulty.
More information: My keyboard is Microsoft Razer Reclusa keyboard. My mouse is a Logitech Wireless Mouse M215.

Below is the dmesg output that I think is relevant to this issue. Here is the output I get when I plug in my USB hub (without anything plugged into it), then plug in the mouse to the hub, and finally plug in the keyboard to the hub:
Code: usb 1-4: new high speed USB device using ehci_hcd and address 80
hub 1-4:1.0: USB hub found
hub 1-4:1.0: 4 ports detected

hub 1-4.1:1.0: activate --> -28
usb 1-4.1.3: new full speed USB device using ehci_hcd and address 83 .....

Interesting to note is that the line that say "usb 1-4.2: reset full speed USB device using ehci_hcd and address 94" increases in the number of times it appears over time. This happens in both scenarios, with the address number changing appropriately. So for example, when everything is plugged in, and I type dmesg, the line appears five times. Then when I type dmesg again, it appears 11 times. etc., for each subsequent dmesg call until the device is disconnected.
