I am trying to get an Apple Aluminium USB keyboard to work that I connect to the USB hub of my monitor.
If I connect it directly to the PC, the keyboard works. If I connect it to the monitor, it doesn't. I'm testing on console mode (tty1) with a second keyboard connected directly to the PC, so it isn't an Xorg issue. When connected to the USB hub in the monitor, "lsusb" reports the following:
Bus 002 Device 006: ID 05ac:0221 Apple, Inc. Aluminium Keyboard (ISO)
(and the entry for the USB hub in that keyboard as well). The monitor is connected via USB 3, and offers USB 3 usb slots. The keyboard works both on USB 2 and USB 3 slots if connected directly.
dmesg throws up the following error when connecting the keyboard to the monitor's hub:
usb 2-1.1.2: can't set config #1, error -28
The same btw goes for the mouse that I try to connect via the USB hub.
Under the monitor's USB slots it reads 5V / 0,9A, but I guess that should be enough to operate a mouse/keyboard. In any case, they get properly recognized but don't seem to get power as the optical mouse's light doesn't go on and the keyboard doesn't get a capslock light.
Monitor is the LG 29EA93-P Rev01.
Any ideas?

It seems to be a 'hardware' problem with the USB hub-chip, see http://comments.gmane.org/gmane.linux.usb.general/72320

What really annoys me is that it works under Windows >:o[
