I am having the exact same problem with the 890. have spent well over 10 hours of time, not including 4 hours on the phone four separate times with Logitech customer support, and I still cannot get the remote and RF extender updated with information which needs to be downloaded from Logitech's website through the USB cable attached to the remote and wireless extender. I have disabled all firewalls and anti-virus programs. Still didn't work.

Then customer support told me it must be a firewall in my wireless router so they recommended bypassing the router. So, I set up a new internet account on my home computer to bypass the router. Still didn't work.

Finally, I called a computer expert who came over to my house and spent another hour and a half and tried to set it up through every possible USB port on three different computers. Still no luck.

I downloaded the software from the disc, so that's not the problem either.

Anyone able to actually solve this problem? Because Logitech customer support can't, nor can a computer expert.
