Corsair Padlock USB does not list under /dev/sd*

Question

I have a Corsair Padlock USB Thumbdrive that used to work fine but it does not mount to Ubuntu 14.04 anymore.

It shows up with lsusb command, also with dmesg and /var/log/syslog file however it is not assigned a /dev/sdX.

This is an encrypted USB drive with pin code entry buttons on it. But I have been using it without encryption or PIN code. The green LED light in the front side of the USB indicates its UNlocked.

Here are couple of command outputs that might help;

$cat /var/log/syslog ... Mar 16 14:26:49 btas kernel: [263193.407994] usb 1-1.2: USB disconnect, device number 6 Mar 16 14:29:12 btas kernel: [263335.950269] usb 1-1.1: new high-speed USB device number 7 using ehci-pci Mar 16 14:29:12 btas kernel: [263336.042691] usb 1-1.1: New USB device found, idVendor=13fd, idProduct=1617 Mar 16 14:29:12 btas kernel: [263336.042696] usb 1-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 ...

Output from dmesg:
$dmesg ... [263335.950269] usb 1-1.1: new high-speed USB device number 7 using ehci-pci [263336.042691] usb 1-1.1: New USB device found, idVendor=13fd, idProduct=1617 [263336.042696] usb 1-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0

Output from lsusb:(the one listed below shows up whenever this Corsair USB is plugged in)
$ lsusb ... Bus 001 Device 007: ID 13fd:1617 Initio Corporation ... However, none of the lsblk, df nor fdisk -l commands list this device since it does not have a /dev/sd* assigned...
Is there a way to manually assign this device a /dev/sdX ? Thank you in advance for any pointers...

Answer 1

I found a Corsair Padlock 2 wasn't appearing and the clue was in /var/log/syslog. It needed a partition table first! Resetting the key completely wipes the device, which includes the partition table.

I installed gparted and ran gksudo gparted. When it opened, I created a new partition table and added a partition on the device. Thereafter, it worked as expected.

This is a different issue to the OP but it came up in Google for me so I add it here for the benefit of others.
