As per http://www.telus.com/content/help/common/pdf/TELUS_TV_user_guide.pdf - page 9: USB port is not enabled.
Also, you should avoid connecting any equipment to the USB ports on the back of your Optik TV digital box. They’re for future use only and you could potentially damage both the equipment and the digital box.
The wireless box is not a PVR, so no. If the USB port on the PVR is working, you might be able to get it to record to an external USB harddrive but the files will all be encrypted to work only with that one specific PVR.
