Add support for Sonoff ZBDongle-E stick

[darkxst]

The Sonoff ZBDongle-E uses a CH9102F UART chip which has a new pid 55D4, but otherwise is very similar to the original Sonoff EFR32 stick. See Issue: #44

This patch adds support for the new pid.

I have tested using the Itead provided firmware

@darkxst Even with these changes I can't flash the Dongle-E. It hangs at line 330. The scan works and the stick is recognized. Do you have an idea?

[darkxst]

@daskruegge Can you paste logs from this failure?

@darkxst I don't have logs, cause there is no error. The script is waiting on the readline at line 330. I validated with print where it is waiting.

If its hanging there, then the dongle probably hasnt entered bootloader mode successfully. Try connecting with a serial terminal such as minicom or putty and see if you get the "Gecko Bootloader" menu prompt.

You can also manually force bootloader mode by using the boot button (requires disassembly).

Edit: Also once a dongle has been flashed with the Router firmware as available on iTead repo, then it refuses to automatically enter bootloader and you would need to use the boot button also.

Thanks, but it still doesn't work. This is what I tried so far:

Connecting to USB without holding boot button

• Doing a scan (green LED)

$ ./ncp.py scan
Connecting to.. /dev/ttyACM0 115200 True False
Exception: <class 'IndexError'> /dev/ttyAMA0
{"ports": [{"port": "/dev/ttyACM0", "vid": "1A86", "pid": "55D4", "deviceType": "zigbee", "stackVersion": "6.10.3-297"}, {"port": "/dev/ttyAMA0", "deviceType": "unknown"}]}

• Trying to flash:

$ ./ncp.py flash -p /dev/ttyACM0 -f ./Z3RouterUSBDonlge_EZNet6.10.3_V1.0.0.gbl
Restarting NCP into Bootloader mode...
SONOFF stick

Connecting to USB with holding boot button -> red LED

• Doing a scan:

$ ./ncp.py scan

NCP no ZigBee Ack. Please try again.

@darkxst Ok, nevermind. It seems like the only problem was that I was trying to do that in a VM 🙈 Trying with the host machine worked. Thanks for your help.
