Arduino esplora briefly shows up in /dev then disappears

I got a new computer and was having difficulty uploading sketeches to my board. I think I did something to my Arduino Esplora Here's the output of

dmesg -w

when the board is plugged in and the reset button is pushed:

[91844.615650] usb 1-14: new full-speed USB device number 115 using xhci_hcd

[91854.995698] usb usb1-port14: unable to enumerate USB device

Note that between

[91844.760801] cdc_acm 1-14:1.0: ttyACM0: USB ACM device

and

[91852.394955] usb 1-14: USB disconnect, device number 115

about 8 seconds later the board shows up as

/dev/ttyACM0

and then it goes away.

I will also add that I was eventually able to upload scripts to my Arduino Nano.
