USB tuner TV don't detecting since last update

I'm having a similar problem.

I have a USB TV tuner setup, but I have it disconnected (have done for ages - no USB slots left), but my Foxtel Cable service was working fine.

Then all of a sudden last night as I was watching my cable service all I saw was "TV tuner not found. We are unable to detect your TV tuner. Make sure your TV tuner is connected to your Xbox, and try again."

I slid to the left to open OneGuide and selected HDMI at the bottom of the list but once I selected it it disappears and all I get is the above message on the screen. I am resetting my whole entertainment system settings again but while HDMI is set in TV
Setup (to test commands to the box), cable shows in the TV example on this screen. So HDMI is definitely working but not while trying to open OneGuide.

Not sure how to fix this, but I'll give Carlos Yo's suggestion below a shot to see if that works.

I just downloaded the May update to try my Hauppauge Tuner (the same one indicated in

support.xbox.com/.../over-the-air-tv) and was disappointed that regional support was not included in the update - though my tuner was detected. Does anybody know if regional support is forthcoming? If not, then I too would love to be in the preview program
so I can use the tuner. Thanks!

Having same issue OTA Xbox USB TV Tuner (Haupage official xbox tuner)

I am having the exact same problem, asking me to plug it in when it is already plugged in. I have tried the fix above but it didn't work for me. Any suggestions?

Same problem, suggested workaround hasn't worked
