Pinnacle PCTV HD Pro Stick (801e)
It would appear that Pinnacle is now selling a new device under the brand "Pinnacle HD Pro Stick", which is significantly different from the previously selling device with the USB ID 801e.
This device appears to be significantly different in architecture, and not a minor revision. In particular, it would appear the new device uses a DIBcom 0700C, as opposed to the older device which used an em28xx device. And the new device uses the xc5000, whereas the older device used an xc3028.
Here are the chips, according to a thread of discussion from the the linux-dvb mailing list:
