Using e.g. slot1 with HOTP needs replug of yubikey after find_yubikey() was called #27

Hi,

after calling find_yubikey() it is needed to replug the yubikey to get e.g. slot1 configured for HOTP working again. Without replug a button press does simply nothing.

Is there any method i can call to "reset" the yubikey so that no replug is needed?

regards the2nd

Hello,

This is a known limitation when this is used with a pyusb before 1.0. What happens is that the kernel driver for hid is detached so the configuration API can be used, but the attach function doesn't exist until pyusb >= 1.0.
