Executa estes comandos por favor, ainda com o pendrive conectado. Ainda não resolvem o problema, estanos só verificando uma hipótese.

sudo usbguard list-devices

[gatohumano]

Obrigado pela ajuda colega de forum,mas entretanto consegui resolver o problema,desinstalei usbguard e voila,problema resolvido,tudo voltou a funcionar normal,parece que esse usbguar é uma especie de firewall para as portas usb.

Opa, que bom que você conseguiu resolver. O resultado do teste que eu pedi ia mesmo nessa direção.
