Hi,
We have tens of CC2530ZNP-Mini kits to be used by students.
There is a lot of problems related to the operation of TUSB based USB to serial converter on the dongle being part of that kit.
1) When using the Sensor Monitor Network GUI about half of the USB dongles are not able to communicate with PC, only changing them makes it possible.
2) when using with Linux (/dev/ttyACM0) the dongle (even in a loopback mode with connected TxD and RxD) work very unreliably, specifically very frequently not responding at all.
Did anyone observed a similar problem and maybe know how to fix it?
