I purchased 16 MC7455 modules from an online retailer within the last 6 months. They are not new, they are pulled from working devices (so I’m told). Out of these 16, 10 of them seem to be DOA.
I’ve tried them in a MOFI device, as well as a USB adapter on both Windows and Linux machines. The 6 working devices are recgonized by the MOFI device and the USB adapter just fine (blue LED lights up on adapter) but with the non-working ones I get nothing. They’re not picked up by windows or linux. No blue LED, no sounds, nothing.
Anyone have any ideas? Is there a way to “wake up” these modules? I’m having a hard time accepting the fact that I received this many dead units. My first order was for 10 and when I realized 6 weren’t working, the company sent me 6 replacements of which only one is working.
Any and all help is appreciated.
