can not download plug ins USB UIRT

hello, I have connected my USB UIRT and it makes me download plug ins failed, try again in ten minutes, I have tried removing and reinstalling the module several times, always the same. all plugins that have a connection with the USB UIRT I can not download, the other plugins (ip camera, squeezbox…) without problems. Is what I’ve forgotten some things to configure in ui4. when I plug the USB UIRT on vera on the USB 1 or 2, only the LED 2 will light.
thanks

Seems i am having the same error, can anyone kick/push me in the right direction? There is just too much info on the USB-UIRT, and some of it really old…

BUMB

Nobody fixed this problem?
