I've had this problem for a while now and I REALLY got tired of it, so here goes: every time I put my PC to sleep mode, when I "wake it up" by pressing the power button, my Mouse and Keyboard either aren't recognized at all (although theres the normal LED flashing on them as if they were working) or they have other bugs, like for example the Keyboard is locked with a certain letter like A or something and it keeps spamming AAAAAAAAAAAAAAAAAAAAAAA.

The only way to fix it is to pull the USB plugs and put them in again - then everything is fine! But as I said above I got tired of unplugging+plugging the USBs of my keyboard and mouse every time, especially since I use sleep mode a lot throughout the day.

Thanks for your tips in advance,
