USB Tuners fail when add USB drive

[taylormadearmy]

Hi All,

I have a strange one...

When I add a USB drive to my WHS SageTV server two of my three USB Tuners stop working.

Has anyone reading this run into a similar issue before or got any ideas how to debug?

Thanks!

No I haven't seen that. I have a WHS server and have added a USB drive as a temporary method of moving files and installing new internal drives. I only have 1 USB tuner-HD-PVR and it didn't cause any issue with that. Try using a different USB port. Don't use a USB hub-pulg it in directly to the PC. The drive may be sucking up too much voltage.

I'm not using a hub but maybe it is something to do with the power the drive draws. Maybe I'll try sticking a powered hub between the drive and the PC to see if that helps.

Thanks!

Most likely it is a USB power issue. Motherboard USB controllers can provide only a small amount of power to connected devices. USB tuners tend to have high power draw. You can power one or maybe two of them directly from your mobo, but not more than that. Use a powered USB 2.0 hub for multiple USB tuners.

I'm managing to power 3 - so I guess I am lucky... And I guess thats why the USB drive screws it up...

Thanks again for the advice.
