The broken one, when plugged into a working USB port, has the LED flash 4 times like this:
3 medium speed flashes
1 quick flash

I'm running Ubuntu. The personalisation tool detects the working one correctly. But not the broken one at all.

I don't even get any mention of a USB device insertion via "dmesg". This is the output from the working one:

Code:
[108419.305552] usb 1-1.3: new low-speed USB device number 13 using ehci-pci
[108419.418609] usb 1-1.3: New USB device found, idVendor=1050, idProduct=0010

[108419.422445] hid-generic xxxx:xxxx:xxxx.xxxx: input,hidraw3: USB HID v1.11 Keyboard [Yubico Yubico Yubikey II] on usb-0000:00:1a.7-1.3/input0


but prints nothing when inserting the broken one.

If the kernel doesn't even see the device, so I would suspect the key is badly broken. Can anyone confirm this, or give me additional debug help?
Thanks
