Apple Event: May 7th at 7 am PT
After installing El Capitan (on mid-2010 iMac) my USB Keyboard (Ducky, not Apple) isn't working anymore.
Please let me know if you have a suggestion,
Thanks,
Hans
iMac, Mac OS X (10.7.3)
I had the same problem. Connecting the keyboard via a powered USB hub allowed me to use it again.

Sadly, a powered USB hub didn't work for me. BTW correction: it does come up in the System Report, and it's true it looks like it doesn't get power.
Comparing to Yosemite, it looks like the drivers changed from IOUSBDevice to AppleUSBDevice, maybe that's part of the problem.
I also get these console messages:
kernel[0]: 006246.302816 AppleUSBHostCompositeDevice@: AppleUSBHostCompositeDevice::ConfigureDevice: unable to set a configuration (0xe0005000) kernel[0]: 006247.000596 K108D@fa131200: AppleUSBDevice::waitForInterfacesGated: timeout waiting for _interfacesMatched kernel[0]: 006247.000631 K108D@fa131200: AppleUSBDevice::waitForInterfacesGated: timeout waiting for _interfacesMatched
please see the solution I posted here, it worked for me
There is a firmware update that fixes the issue. Contact support (support@duckychannel.com.tw) and they will send you the firmware. You need to apply it using Windows. But it works perfectly after that.
Thanks for letting me known TobiasC, didn't receive an email yet from support (mailed them last week). Could you maybe forward your information to me? (mail@hanspinckaers.com)
I have the same problem when using a wired Apple keyboard plugged into my KVM switch. I get a pop-up message saying the USB Keyboard hub needs more power and I have to plug it into a hub to get it to work (and the hub doesn't even have to be plugged in). Unfortunately, when I do that, my PC laptop won't recognize the keyboard. This was not an issue before I upgraded to El Capitan. Other keyboards work fine.
Thought I would add I have the same problem on two different MacBook Pros and two different Ducky keyboards.
For one (2014 model), I reinstalled OS X El Cap and it started working. The other MBP (2012 model) was not fixed via this method.
As such, this might work as a "quick" fix, but seems flakey.
For completeness, my keyboard shows up under System Information.
I will give the firmware option a go now...
I had the same issue and managed to fix it by using an apple USB extending cable. It seems to be because it can't handle the USB connectors that have a notch in the middle (see attached image)
Hope this helps!

None of the mentioned fixes worked on my Ducky keyboard.
However just few minutes ago, I tried plugging in my keyboard to a Macbook with the latest version of El Capitan (10.11.1) and it worked perfectly. Looks like they have fixed the issue in the latest update.
I have an Apple USB keyboard from a eMac. Worked under Yosemite, does not work when plugged in directly to the iMac under El Capitan. Does seem to work on a powered USB Hub.

It does seem to work on a powered USB Hub.
AND it does work when plugged into an extender cable (mine is Belkin) plugged into the iMac USB.
Dang Apple creates some weird issues!
dude.. this worked for me!! ben wrestling with this off and on for a few months. Thanks!
