Waiting for USB request failed Exception #424

Closed sylwek845 closed 2 years ago

sylwek845 commented 2 years ago

Hi, I'm getting the following exception

java.io.IOException: Waiting for USB request failed at com.hoho.android.usbserial.driver.CommonUsbSerialPort.read(CommonUsbSerialPort.java:192) at com.hoho.android.usbserial.driver.CommonUsbSerialPort.read(CommonUsbSerialPort.java:157) at com.hoho.android.usbserial.util.SerialInputOutputManager.step(SerialInputOutputManager.java:224) at com.hoho.android.usbserial.util.SerialInputOutputManager.run(SerialInputOutputManager.java:202) at java.lang.Thread.run(Thread.java:920) I'm getting this after calling SerialInputOutputManager(port, this).start() but noticed when I do this val man = SerialInputOutputManager(port, this) Thread.sleep(500) man.start()

it won't crash for 500 mills and I can recieve the data. Do you have any idea what may cause the issue? My implementation is almost identical as the one in the example. Thanks
