CH340/341 improved support in UsbSerial 4.2

UsbSerial supports the problematic CH340/341 chipset from 3.0 but the implementation lacked of some necessary features. Finally I managed to get some time to improve CH340 and I gladly announce that CH340/341 support has taken a very long leap!

Current Features
– Broader range of baud rates supported: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600
– Flow control support for RTS/CTS and DTR/DSR.
– All parity modes.

With this new driver the support for the Arduino clones should be better.

Happy hacking!


DroidTerm 6.5 now supports for Arduino clones using CH340/CH341 chipsets

Last information about the current state of DroidTerm. Please check it out

As title says, I’ve managed to add support in DroidTerm and UsbSerial for those cheap Arduino clones which use the Ch34x family usb to serial chipsets (thanks Paul for providing me with one).
Besides of that. I fixed two bugs:
– A bug that appeared when a CDC device connection was disconnected and reconnected without unplugging.
– Now DroidTerm keeps logging data (if a profile was created) when the screen is turned off.

I hope DroidTerm is still useful for you guys and I hope I could start to add some new features soon.
