I am trying to connect minicom to a serial device that is connected via a USB-to-serial adapter. This is a PL2303 and from everything I've read no additional drivers are required. Factory Installed Os Vista Hp G60.

Is this the correct command to execute? Or do I need to configure something? $ sudo minicom --device /dev/ttyUSB0 minicom: cannot open /dev/ttyUSB0: No such file or directory $ sudo lsusb -v Bus 002 Device 006: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port Device Descriptor: bLength 18 bDescriptorType 1 $ tail /var/log/syslog #then removed and attached the device.

I get get the same minicom error, 'cannot open /dev/ttyUSB0: No such file or directory' Three notes: • I get the error when the device attached to the serial port end of my Prolific Technology PL2303 USB/Serial adapter is turned off. After turning on the device (an embedded controller running Linux) minicom connected fine.
