Perhaps someone could use this. TIA.
Mounted an EXT4FS SD card (apparently). Removed the USB readed (with the card) from the machine. Core i7 CPU, x86-64. Fedora normal kernel.
Now mounting: usb 3-14: new high-speed USB device number 34 using xhci_hcd usb 3-14: New USB device found, idVendor=05e3, idProduct=0738, bcdDevice= 0.01 usb 3-14: New USB device strings: Mfr=3, Product=4, SerialNumber=5 usb 3-14: Product: USB3 Reader usb 3-14: Manufacturer: Genesys usb-storage 3-14:1.0: USB Mass Storage device detected scsi host8: usb-storage 3-14:1.0 scsi 8:0:0:0: Direct-Access Generic STORAGE DEVICE FT01 PQ: 0 ANSI: 6 scsi 8:0:0:1: Direct-Access Generic STORAGE DEVICE FT01 PQ: 0 ANSI: 6 sd 8:0:0:0: Attached scsi generic sg4 type 0 sd 8:0:0:1: Attached scsi generic sg5 type 0 sd 8:0:0:1: [sdf] 31116288 512-byte logical blocks: (15.9 GB/14.8 GiB) sd 8:0:0:1: [sdf] Write Protect is off sd 8:0:0:1: [sdf] Mode Sense: 21 00 00 00 sd 8:0:0:1: [sdf] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA sd 8:0:0:0: [sde] Attached SCSI removable disk sdf: sdf1 sdf2 sd 8:0:0:1: [sdf] Attached SCSI removable disk EXT4-fs (sdf2): recovery complete EXT4-fs (sdf2): mounted filesystem with ordered data mode.
