No Ubuntu 11.04, eu imprecisamente clicou com o botão direito e "desmontou a unidade com segurança" da minha Sony HDR-XR150 conectada via USB. Agora, quando eu conecto minha câmera digital em meu computador via USB, o Ubuntu não registra a nova unidade, ou pisca brevemente a tela "reconhecimento e escolha do que fazer com a unidade USB".
Por favor ajude.
FYI, corri dmesg com os seguintes resultados:

Já faz 7 anos, ainda, eu também tenho esse problema. O problema é a falta de suporte exFAT. Então, isso deve ajudar:
sudo aptitude install exfat-fuse
