A while back I purchased a 1 x waysmall 400xm-bt (with 5v US power adapter and duck antenna ).  This wasn't cheap,  I paid about 200 bucks for it.  It has never worked.  I've tried to connect to it using, kermit, minicom, screen, and usbnet.  
The only indication that this piece of crap even works is that the green led lights up.   Does any body know how I can reset it back to the factory default.  Or should I just toss it into the trash.
