[quote="Newman, post: 18186"]The new USB programming cables are native USB devices and they have been tested under Windows XP. They have not been tested under Vista so there's a chance that there's a driver issue. Re the EComPort error, with the current release of CIRCA there is an issue where having anything connected to COM1 on the PC will make the USB programming cable fail. The solution is to close any programs that may be using COM1 before attempting to download to your unit. The issue with the old serial programming cables on some laptops was a hardware issue with the low-power serial drivers used by some manufacturers.[/QUOTE] The issue about COM1 being open will be fixed in the next release of CIRCA. As for Windows Vista, I have used the cable under a Vista installation and it does seem to work fine, so hopefully you have no issues there...
