Попробуй в BIOS найти что то типа PS/2 legacy mouse, тогда USB должна заработать, и почитай инструкцию к матери, вроде на новый матерях с одним PS/2 туда можно либо клаву, либо мышь подключать.
Thanks for testing! I switched virtualbox audio to "Intel HD audio", it had no effect, but then I switched audiodriver from pulse to ALSA (I'm running Linux) and now delay is gone. Great. I tried Intel HD Audio before and I tried ALSA before but I never tried both in same time BTW, are you using auto-translator to understand russian language? I'm not sure if I should translate my posts to English or not. _________________ Roman Shuvalov
