  VillainK1

   [2]VillainK1 Are you using it via a usb hub? and plugging it in before you
   boot the mini?

   --------------------------------------------------------------------------

  VillainK1

   No i plugging it directly its a corsair k90 it need 2 usb ports!!! I have
   plugged it in before i boot not working!!!

   --------------------------------------------------------------------------

   Try it in a mains powered usb hub if possible. via the mini

   a corsair k90 is going to need quite a lot of power.

   a REALLY powerful psu or a powered hub is necessary.

   [3]walnutwhip I wasn't sure of the power needs, but with 2 inputs its got
   to be a lot.
   I just use a cheap usb keyboard at the moment.

   Does it need two USB ports to work or is the second just extra power for
   devices that connect to the keyboard as a hub?

   I ask because I'm using a Das Keyboard myself, which is a mechanical
   keyboard with two USB plugs. I simply have only one plug in - you might
   need to experiment to see which is the right plug.

   [4]mr_appleby 1usb is just for power but not working i try with powered
   usb hub too both not working not compatible

   [5]VillainK1 no worries I forgot about the RGB lighting on the corsair.

   a corsair k90 needs one usb 3.0 or 2 usb 2.0 for the power.

   usb 2.0 only supplies half the needs for a k90. as memory serves, im using
   a corsair k90 right now, with its rgb lighting etc.

   you are not going to power a k90 with one usb port on a mini. you
   definitely need a powered hub with 2 free ports on it.
   i would say a 2.5amp hub at least.

   those k90s need power for all that rgb stuff.
   even if you dont need, or use, it.

   [6]walnutwhip i have try with a (Aten US224 USB Switch ) 2 Free usb Port
   with power connector Not Working Dude!!
   The K90 have power, but no response from the C64 Mini
