USB-UIRT not working after upgrade to 1.5.408

I have just made the upgrade to 1.5.408 and now my devices associated to the USB-UIRT no longer work.

Here is the message in the logs:

02 08/30/12 22:05:40.813 JobHandler_LuaUPnP::RunAction device 53 action urn:micasaverde-com:serviceId:MenuNavigation1/Down failed with -115/Unknown USB_UIRT Service <0x2e76e680>

I have checked the association and it’s ok (these all got reset after the upgrade so had to reassociate). I have also tried unplugging and reconnecting the USB-UIRT.

Any ideas? Info on USB-UIRT troubleshooting seems thin on the ground.

Many thanks,

Chris
