desde hoje tenho o problema de (apenas) meu mouse congelar duas ou três vezes por minuto durante 2 a 3 segundos. Não tenho certeza se é coincidência, mas começou desde que instalei o VirtualBox. Antes eu conseguia resolver conectando o mouse em outra porta USB, mas agora o problema aparece novamente. Cada vez que meu mouse trava, recebo uma nova identificação USB (dmesg):

Provavelmente são os módulos de integração do VirtualBox que fornecem as portas USB do host para os sistemas operacionais convidados, que não funcionam corretamente.
Tente dizer ao VirtualBox para deixar as portas USB do host em paz.

Enquanto isso, não acho que seja um problema do VirtualBox. Pois hoje mudei para o Ubuntu Maverick e o problema ainda persistia. Depois que comprei outro mouse, o problema desapareceu repentinamente. Nem mesmo quando reinstalo o Virtualbox e executo as imagens, recebo atrasos no mouse. Eu teria dito que isso é um problema do mouse, mas não explica por que o navegador congelou em intervalos constantes (como aconteceu com o ponteiro do mouse) enquanto eu executava o qemu-img convert -O raw myfile.vhd myfile.bin. E ainda não reinstalei o qemu porque não preciso dele no momento, então talvez o qemu ainda faça algo "especial" no sistema. Além disso, não explica por que o mouse antigo funciona com meu notebook Ubuntu. Mas ok, vou deixar isso por enquanto, porque funciona no momento.
