I think I have done something wrong but after troubleshooting this whole time, I think it's better for me to ask here.\r\n\r\nI git pull your repo and change the SDK path then perform the usual \"make\" and \"make burn\" as shown in your video which compiles and flashes with ease and no error.\r\n\r\nHowever, after wiring up my NodeMCU with USB Type B then connect to my Linux machines, these are the output I got from dmesg:\r\n\r\nWiring the ESP8266 to my Ubuntu 16.04 machine I get this messages:\r\n[593134.728040] usb 3-1: new low-speed USB device number 5 using uhci_hcd\r\n[593135.144039] usb 3-1: device not accepting address 5, error -71\r\n[593135.144217] usb usb3-port1: unable to enumerate USB device\r\n\r\nWiring to Raspberry pi 3 (Raspbian Jessie):\r\n[ 7814.928437] usb 1-1.4: new low-speed USB device number 72 using dwc_otg\r\n[ 7815.348436] usb 1-1.4: device not accepting address 72, error -32\r\n[ 7815.348535] usb 1-1-port4: unable to enumerate USB device\r\n\r\nWiring to OpenWRT 15.04:\r\n[25945.270000] usb 1-1: new low-speed USB device number 6 using ehci-platform\r\n[25945.750000] usb 1-1: device not accepting address 6, error -71\r\n[25945.750000] usb usb1-port1: unable to enumerate USB device\r\n\r\nMy first schematics I added a 100ohm pull up resistor to D- (GPIO12) to 3.3v.\r\n\r\n![v1](https://cloud.githubusercontent.com/assets/4161783/17542026/c3200c0e-5ef7-11e6-8f0d-6eae94f35e5c.JPG) (EDIT BY CNLOHR: NOW GPIO4/5)\r\n\r\nThen later I added a pull down resistor to D- and D+ but still no luck.\r\n\r\n![v2](https://cloud.githubusercontent.com/assets/4161783/17542044/d83b0828-5ef7-11e6-8618-9af96349817a.JPG) (EDIT BY CNLOHR: NOW GPIO4/5)\r\n\r\nDid I do a mistake somewhere or missed out a step?

This is very strange and an actual problem.  Would you mind trying with different baud rates on Linux?  (Sorry, I am grasping for straws).\r\n\r\nP.S. Pull the newest version and GUI.  I think you'll really like the demo :-D.  Be sure to connect to the wifi with a mobile device."}}
