[FONT=Verdana][SIZE=2]Also check Voltages on board:
- GND to connection between D1 and D2 - should be ~5V
- GND to TP-1V8 - 1,8 V
- GND to TP-1V2 - 1,2 V
- GND to D6-A - 3,3 V
- GND to 3V3 - 3,1 V (Falling voltage on D6)
You can try power 5V from external power supply, but it must be done carefully (some resistance in serial, starting from [/SIZE][/FONT][FONT=Verdana][SIZE=2]4[FONT=Univers Condensed CE][I]7[/I][/FONT][FONT=Univers Condensed CE][I]Ω [/I][FONT=Verdana]and making it smaller until a connection[/FONT][/FONT]). In other way you can power targets 3,3V externally, so it cause to make power consumption from USB smaller...
It will be nice if CR Crew will release open source kernel proto-driver for own link device... ;)
