I installed the ConvertX upon purchasing. It worked great. Then I did not use it for a time, when I went to use it would not work. I contacted Plextor and they did some troubleshooting and issued a RMA. I sent the box back, upon receiving the replacement I tried again and had the same problem. I contacted Plextor and they issued a RMA for the box and the adapter. Upon receiving the ConvertX box and adapter back I tried again. It still did not work, so even though I had tried a different USB cable I went out and purchased a new one. The new one did not have any plastic on the inside of the connection area. I plugged it in and everything worked great until yesterday. Now it does not want to work again. I am getting the same cannot recognize the USB connection.
The only thing I did was unplug the device so I could move things around and plugged it back in. NOW NOTHING WORKS AGAIN. There is a yellow diamond for the multimedia controller - I have sound as I am archiving cassettes for our parish and have been working on them as I try to troubleshoot this problem.
