Device not found for specific operations

[Gabgobie]

The device didn't work with any device other than my iPhone after initializing via NFC so I wanted to reset it and try if it works with everything if I init on PC.

When trying to factory-reset the device (NK3A) I get a device not attached error. Other operations run successfully.

Tested:

• nitropy nk3 factory-reset (fails)
• nitropy nk3 factory-reset-app (lists 5 apps of which only opcard supports reset?)
• nitropy nk3 test (success)
• nitropy nk3 rng (success)
• nitropy nk3 list (success)
• nitropy nk3 secrets reset (success)
• nitropy nk3 list-config-fields (success - lists 4 fields)
• nitropy nk3 get-config <every field> (success)
• nitropy nk3 status (success)
• nitropy nk3 wink (success)

Edit: The part with it working on iOS but not PC may have been a combination of bad/inconsistent browser UX, OS and website.
