Post USB dongle.


Hello,
I'm using Linux and I want to know how can I copy a USB dongle? Some devices need special USB dongle to work and when I plug it to my system then Linux tell me that a new device attached, but nothing mounted!
Code:
[18167.789715] usb 2-8: new high-speed USB device number 4 using xhci_hcd
[18167.939101] usb 2-8: New USB device found, idVendor=0c76, idProduct=0005, bcdDevice= 1.00
[18167.939105] usb 2-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[18167.939108] usb 2-8: Product: USB Mass Storage
[18167.939111] usb 2-8: Manufacturer: GENERIC 
[18167.940237] usb-storage 2-8:1.0: USB Mass Storage device detected
[18167.940608] scsi host6: usb-storage 2-8:1.0
[18168.954318] scsi 6:0:0:0: Direct-Access     GENERIC  USB Mass Storage 1.00 PQ: 0 ANSI: 2
[18168.954752] sd 6:0:0:0: Attached scsi generic sg3 type 0
[18168.955461] sd 6:0:0:0: [sdc] Attached SCSI removable disk
How can I access to this device?

Thank you.

does this device work ? I mean in another computer/OS/whatever?
what will lsusb and lspci say?
Probably you will find more lines related to sdc (the given device) in dmesg.

If by USB dongle you mean a license key they are not a USB drive and can not be copied. That would also be against the sites rules.

This is it: ID 0c76:0005 JMTek, LLC. Transcend Flash disk
you can also try: lsscsi
probably you can find something useful here: https://ubuntuforums.org/archive/ind...t-2245366.html

Just because it presents to the OS as a Mass Storage Device doesn't mean that it can necessarily be accessed as such. It may require some form of communication protocol that the protected software uses via the low level device.

As has also been previously pointed out, copying something or attempting to defeat licensing is against the rules of this site.

0c76 JMTek, LLC. 0005 Transcend Flash disk

Is this correct for what you have? It is not normally called a dongle. Is this a secure model?

Open partition software. Gparted or such to see what it reports.

USB != disk

A lot of things can be hung off a USB port. Wireless keyboard and mouse interfaces are pretty common, for example.

I am familiar with commercial products (VAX and Alpha emulators) that use such a USB dongle in lieu of a license file that might normally be saved on a disk. You would have to dig deep into the hardware contained in such a device to reverse engineer and duplicate it. Not my forte, and as a few others have pointed out, not something anyone on this forum is going to engage in.

HTH...

I don't think too much should be read into the nomenclature. In many countries a USB flash drive is just called a USB. True, that's not accurate, but it's what is used. The OP's output shows a generic storage device, probably a cheaper unbranded USB flash drive, which is not automounted. The lack of an automount is probably a DE setting, but without knowing the DE it's hard to recommend a method to enable that. The drive can be manually mounted to whatever mountpoint is desired. Probably safer to make a mountpoint, and /media is the traditional place for it. One possibility:
Code:
sudo mkdir /media/temp
sudo mount /dev/sdc1 /media/temp
This assumes that the device is seen as /dev/sdc, and has one partition on it. That part may need to be adjusted. Run lsblk to find the device and the actual device name. If the device has uses other than generic data storage then some things may need to be adjusted, but without knowing more that's impossible to say.
