Well, here's a very similar log from a USB stick being inserted: [] usb 1-4: new high-speed USB device number 8 using xhci_hcd [] usb 1-4: New USB device found, idVendor=0c76, idProduct=0005, bcdDevice= 1.00 [] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [] usb 1-4: Product: DataTraveler 2.0 [] usb 1-4: Manufacturer: Kingston [] usb 1-4: SerialNumber: 2731542023F1DE82 [] usb-storage 1-4:1.0: USB Mass Storage device detected [] scsi host3: usb-storage 1-4:1.0 [] scsi 3:0:0:0: Direct-Access Kingston DataTraveler 2.0 4.10 PQ: 0 ANSI: 2 [] sd 3:0:0:0: Attached scsi generic sg1 type 0 [] sd 3:0:0:0: [sdb] 503808 512-byte logical blocks: (258 MB/246 MiB) [] sd 3:0:0:0: [sdb] Write Protect is off [] sd 3:0:0:0: [sdb] Mode Sense: 0b 00 00 08 [] sd 3:0:0:0: [sdb] No Caching mode page found [] sd 3:0:0:0: [sdb] Assuming drive cache: write through [] sdb: sdb1 [] sd 3:0:0:0: [sdb] Attached SCSI removable disk > Its a u-sd card Well, here's a very different log for a card: [] pciehp 0000:00:1c.3:pcie004: Slot(3): Card present [] pciehp 0000:00:1c.3:pcie004: Slot(3): Link Up [] pci 0000:03:00.0: [10ec:5227] type 00 class 0xff0000 [] pci 0000:03:00.0: reg 0x10: [mem 0x00000000-0x00000fff] [] pci 0000:03:00.0: supports D1 D2 [] pci 0000:03:00.0: PME# supported from D1 D2 D3hot D3cold [] pci 0000:03:00.0: BAR 0: assigned [mem 0xb1000000-0xb1000fff] [] pcieport 0000:00:1c.3: PCI bridge to [bus 03-08] [] pcieport 0000:00:1c.3: bridge window [io 0x3000-0x3fff] [] pcieport 0000:00:1c.3: bridge window [mem 0xb1000000-0xb1ffffff] [] pcieport 0000:00:1c.3: bridge window [mem 0xb0000000-0xb0ffffff 64bit pref] [] rtsx_pci 0000:03:00.0: enabling device (0000 -> 0002) [] mmc0: cannot verify signal voltage switch [] mmc0: new ultra high speed SDR104 SDHC card at address aaaa [] mmcblk0: mmc0:aaaa SE32G 29.7 GiB [] mmcblk0: p1 So forgive my mistake. OTOH, here's exactly the same card: [] usb 2-2: new high-speed USB device number 7 using xhci_hcd [] usb 2-2: New USB device found, idVendor=0781, idProduct=a7a8, bcdDevice= 1.27 [] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [] usb 2-2: Product: SDDR-113 [] usb 2-2: Manufacturer: SanDisk Corp.

Well, at least one of my guesses was correct. Any chance of responding to more than one item at a time? Dan asked for a listing of the partition table, and I asked how the "device" was written. I might as well add the question: does the second partition fare any better on mounting? Cheers, David.
