USB-UIRT Forum

I recently bought a USB-UIRT (S/N 130481) from Snapstream for use with BTV and a Pace DC50X set top box to convert Comcast digital to analog. I use a Hauppauge HVR 1600 PCI tuner card. I’m running Win XP/SP3 with BTV 4.9.2 and a FireFly remote. The PC is a generic dual-core Celeron with an Intel G31 chipset.

I’ve installed the version 1.4 driver. The USB-UIRT shows up under the USB section of Device Manager and claims to be “working properlyâ€

I don't use BTV, but you can verify that the USB-UIRT is working correctly using lrnhelper. Lrnhelper is a simple app provided by USB-UIRT support. the app can be downloaded from here. Using lrnhelper, learn an IR transmission from an OEM remote and then transmit to see if it works. If it works, your problem is with the setup between BTV and the USB-UIRT - not the USB-UIRT itself.
