I'm running the latest Debian image
  
http://rcn-ee.net/deb/testing/2014-02-18/BBB-eMMC-flasher-debian-7.4-2014-02-18-2gb.img.xz

When I plug in my USB devices (a Dell keyboard + USB mouse),
only the keyboard is seen?

root@beaglebone:~# lsusb
Bus 001 Device 002: ID 04b4:6560 Cypress Semiconductor Corp. CY7C65640 USB-2.0 
"TetraHub"
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 413c:2105 Dell Computer Corp. Model L100 Keyboard

If I plug in just the mouse with no hub, I get this:

root@beaglebone:~# lsusb
Bus 001 Device 004: ID 046d:c03d Logitech, Inc. M-BT96a Pilot Optical Mouse
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I tried another (unpowered) hub where nothing but the hub is seen:

[ 1058.647749] usb 1-1: device descriptor read/64, error -110
Bus 001 Device 000: ID 05e3:0606 Genesys Logic, Inc. USB 2.0 Hub / D-Link 
DUB-H4 USB 2.0 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Both of these hubs (and devices) work on my other platforms.

Any ideas what this might be?
