Blackmagic Forum

Hi, any help appreciated please. I've just unpacked a brand new Ultrastudio Recorder 3G. I'm familiar with this product as I've used several before. I've connected this one to a new PC laptop with Thunderbolt4, a brand new Mac Mini M1, and a recent MacBook Pro, using 3 different thunderbolt cables. Not once has the LED beside the Thunderbolt port EVER illuminated on the device. As such, the computers at best tell me the device has "limited functionality". As such, the BlackMagic Desktop Video does not detect any sources. The LED indicator on the device should light immediately on plugging in with a genuine thunderbolt cable right? Is it possible this unit is faulty out of the box? Again, any help or advice appreciated. Thanks.

Problem solved. Turns out it was the cables I was using not being Thunderbolt 3 compliant. Apparently cables that come with brand new Ipads are not Thunderbolt - just USB-C. I've learnt a cable lesson.
