SOLVED Prolific PL2303 Driver no longer initializes

Re: Prolific PL2303 Driver no longer initializes

Thank you MrEngman You were correct the directory did not exist, so I created it. Update completed successfully. However I still cannot initialise the PL2303 and access my CurrentCost envir via ttyUSB0 in perl. I think the issue maybe related to the fact (that I haven't previously mentioned!) I use ...
