| Post subject: | NFC doesn't work, LED flickering |
Hi, i've got a yubikey neo a few month ago. it works without any problems in the first weeks. but now... Problem 1: my smartphone doesn't react when i tap it my yubikey on it. i've tried another smartphone and got the same issue. NFC is enabled. Problem 2: when i plug it into my pc, the LED flickers and go on and off. when i use the personalization tool the yubikey connects and disconnects the whole time. i can write but sometimes i've got write errors. tried it with different usb ports with enough power. i can fix it when i disable CCID in the neo manager, but thats not what i want. i got a new yubikey and this one seems to work so far. i am a little bit confused what happens with the old one and be a little bit scarred that it happens again. are that known issues with the neo? my new neo got detected with yubiclip on android. but when i use taginfo to see informations, it reads the neo, but only shows a few NDEF data and got the error "there seems to be serious communication errors". don't know what is wrong. thx |
