![]() Emulate standard UART interface, used to upgrade the original serial peripheral or expand additional UART via USB.Full-speed USB device interface, USB 2.0 compatible.For more information about converting USB to printer interface, please refer to the CH340DS2 datasheet. In UART mode, CH340 provides standard MODEM signals, used to extend serial port for computers, or upgrade directly from normal serial device to USB bus. I did that and voila!īottlerocket is able to communicate with my X-10 devices.CH340 is a USB bus converter chip which converts USB to serial port or printer port. This is required for proper use of bottlerocket. This helpful tip: This package uses debconf to configure the /dev/firecracker symlink, should you need to change the symlink in the future run this command: dpkg-reconfigure -pmedium bottlerocket That will then prompt you for your new serial port and modify the symlink. In additon to adding myself and br to group dialout, I found in the README.Debian file in /usr/share/doc/bottlerocket. I just got my GUC232A cable with molded in pl2302 converter chip. Just exiting the terminal session running minicom, will leave the process running. In this situation, make sure the device is attached to VM operating system by right clicking on the USB/Serial usb icon in the lower right of the VMWare window and select Connect (Disconnet from Host) Remember to press Ctrl-A to get minicoms prompt, type X to exit the program. I am running Ubuntu 10.04 LTS under VMWare (runing on Windows 7). Sometimes I have to unplug and plug back in the USB/Serial adapter to get minicom to connect to it. ![]() I have to run as super user (i.e sudo minicom). After turning on the device (an embedded controller running Linux) minicom connected fine. I get the error when the device attached to the serial port end of my Prolific Technology PL2303 USB/Serial adapter is turned off. I get get the same minicom error, 'cannot open /dev/ttyUSB0: No such file or directory' Three notes.

Is this the correct command to execute? Or do I need to configure something? Ubuntu Usb Serial Driver ![]() This is a PL2303 and from everything I've read no additional drivers are required. I am trying to connect minicom to a serial device that is connected via a USB to Serial adapter.
