I have a CurrentCost electricity usage monitor which is normally connected to my desktop via USB. When the unit is plugged in I get a number of lines in syslog like so:
kernel: usb 4-1: new full speed USB device using uhci_hcd and address 12 kernel: pl2303 4-1:1.0: pl2303 converter detected kernel: usb 4-1: pl2303 converter now attached to ttyUSB0
I am trying to get this same device working on my laptop but this time I see the following in syslog:
kernel: pl2303: Prolific PL2303 USB to serial adaptor driver
but nothing else i.e no 'attached to ttyUSB0'. Looking in /dev there is no ttyUSBn
Whereas the desktop also loads the pl2303 and usbserial kernel modules automatically when the device is connected the laptop does not and when I load them manually I get only the above mentioned line in syslog.
Needless to say the software which monitors the device won't connect.
Any suggestions?
