Updated code and USB usage

[patrickpoirier51]

These are my notes on how I kinda made it work

The ec2 code need to be updated, here is one that works:
https://github.com/paragonRobotics/ec2-new
Git clone
make a build directory and ccmake from there
make
copy ec2/build/bin to /usr/local/bin

Now the fun part:
using dmesg , check how the EC2 is handled by kernel, here is mine:

[ 2419.004111] usb 5-1: reset full-speed USB device number 7 using uhci_hcd
[ 2485.360286] usb 5-1: USB disconnect, device number 7
[ 2487.868207] usb 5-1: new full-speed USB device number 8 using uhci_hcd
[ 2488.050384] usb 5-1: New USB device found, idVendor=10c4, idProduct=8044
[ 2488.050388] usb 5-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 2488.050390] usb 5-1: Product: USB Debug Adapter
[ 2488.050392] usb 5-1: Manufacturer: Silicon Laboratories
[ 2488.050394] usb 5-1: SerialNumber: EC3005AC7E3
[ 2488.074188] hid-generic 0003:10C4:8044.0007: hiddev0,hidraw1: USB HID v1.11 Device [Silicon Laboratories USB Debug Adapter] on usb-0000:00:1d.0-1/input0

We need to unbind so the ec2 progs can get access:
echo -n 5-1:1.0 | tee -a /sys/bus/usb/drivers/usbhid/unbind

So based on that , we can make a devrule to unbind while pluging:
sudo nano /etc/udev/rules.d/99-ec2.rules
SUBSYSTEM=="usb", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="8044", MODE="0660", GROUP="plugdev", RUN="/bin/sh -c 'echo -n $id:1.0 > /sys/bus/usb/drivers/usbhid/unbind'"

Activate rule:
sudo udevadm control --reload
sudo udevadm trigger

Simple test , that read EC2 Firmare and write to file
./ec2readfw --port=USB test.bin
