I don't have the 4250HDC, but I do have the 4250C. I don't know how
similar they are, or if the "HD" in there make them completely different
STBs. Theoretically, I plan to run mine with the IR-blaster on my
HVR-1600, but I recognize that that IR blaster is a bit of an oddity,
and I've had trouble trying to use a conventional IR repeater with the
STB, so I'm a little fearful that there's something non-standard about
The box also has a USB jack on the front, so one day just for jollies I
plugged a keyboard into it. The number keys work, and change the
channels. I didn't mess much more than that, and in particular I don't
know if there is some sort of keycode that will turn the STB off. The
linux kernel has support for "USB gadgets", meaning that with the
appropriate cable can act like a USB peripheral (such as a keyboard) to
some other USB host controller. (like the STB) One of those gadget
devices that was planned was a keyboard, but I haven't been able to find
anything further than "planned." Still, it may be an option. If I get
to the point of trying my IR blaster and fail, I may have to be
reexamining this one.
