Unfortunately, come with me always the message that is exceeded, the power supply as soon as I plug in a USB flash drive into the USB hub.
I now have all USB sticks tasted by me: 16 GB Disc San Cruzer, 16GB Super Talent and 1GB noname not work but the 512MB noname works without problems.
The keyboard is really really good but who wants to use the USB port with stick should leave it alone. 512MB are probably out of date and at the same time an indictment of Logitech.
In the product description, the USB stick is large advertised can be operated, only the size was not specified there. For me, this was a crucial selling point. I'll give the keyboard back, for me this is not to be used when USB sticks do not function. Too bad I thought I had now found the right keyboard for me and I need make no more gymnastics exercises to gleangen to my PC USB, which is under the Schribtisch. Do I need to probably look for yet more money or tired of forking out for the G19.
The programming of the G keys I after the bankruptcy with the USB Hub not even try and can not say anything.
