In the case 2) it is most probably caused by this: Such device is not mass storage class device. I.e., it probably needs some additional special driver. You can check this by lsusb -v Mass storage device should have something like this (important are values in last three rows): ... Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 8 Mass Storage bInterfaceSubClass 6 SCSI bInterfaceProtocol 80 Bulk-Only ... I have Dell Latitude E6500 - there is also smart card reader (connected directly to UHCI controller) and its interface descriptor unfortunately looks like this: ... Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 3 bInterfaceClass 254 Application Specific Interface bInterfaceSubClass 0 bInterfaceProtocol 0 ... Additionally - this smart card reader device is (AFAIK) also usually not recognized by BIOS (it is not possible to boot from this device - at least on my notebook).
