4 years ago Hmm, I haven't seen this one before. When you encounter the issue you say that a reboot typically of the computer fixes it? Have you tried other things, like removing and re-inserting the YubiKey? Have you seen this issue on more than one physical computer?

4 years ago (sorry for the delay in responding -- needed to clear some time for proper troubleshooting)
I've spent more time poking at it today and it seems to be isolated to one system, a Lenovo Thinkpad T470s notebook. I don't have any other issues with the yubikeys with the system (using them on the cli for challenge-response & u2f, and in Chromium for Google account security keys), but on this notebook in particular (tested with my 2 Yubikey 5 NFCs) I consistently end up in this state:

OSError: Invalid value size specified(this is after a fresh install of Ubuntu 20.04; same results with both keys)
I wasn't able to reproduce the issue on another desktop, which leads me to believe it's some oddity of this system specifically.
If troubleshooting it would be helpful for the project and others, I'd love to do it. ~If it affects literally no one else and there's no clear path forward, then I'll understand if we want to just close the issue again.~
If it could potentially affect others in the future, I'd love to help troubleshoot it, but understand if that's not feasible/practical.
I'm running into an issue where my Yubikey 5 NFC becomes unusable after a some time (typically fine after a reboot, but then this issue comes back after a couple of days). Doesn't seem specific to older or newer library versions (had this same issue in the 0.7.x versions on a ubuntu 19.04 system, and I'm seeing it still with a fresh ykman install on a ubuntu 19.10 system)
The exact output looks like:
If I add a debug print line to that ReadLsbBytes function, it's a bunch of 1s, a few 2s, and then a 0 causes that ^ exception.
Not sure if there's some method of resetting or troubleshooting I can provide, but would love to help.
