I finally found out the cause for this, still no idea about a proper solution. I am using vmware horizon to connect to a windows computer, it has a funcion called usb redirection that allows you to use your usb from the windows computer. It seems that when vmware horizon is open, the usb devices are redirected there and my laptop doesn't see them, when I close it, everything works normally. So I suppose that the issue can be closed. Thanks for your help
