The problem probably being poor design and shielding on modern computers. I’ve also had some issues with ground loops but that is only in very specific circumstances. The problem I’ve found with a LOT of USB things even the FTDI ones is that they’re only putting out a stepped up 12V or even just 5V while classically the serial port was a bit above 12V. I skimmed a bit of that link and it seems that a number of those interfaces are disappointments.
Device Manager, Properties sheet for the USB Serial Port, Port Settings tab, Advanced button. The COM Port Number may change if you plug the interface into a different USB port, so I’d recommend always using the same USB port. Now extract the CH340g drivers in a folder and in that you will find folder named “CH341SER” in which there will be a “setup” application file as shown below.
Run http://driversol.com/drivers/ftdi this utility to see if you have a fake chip. Send in your device and they would replace the chip with genuine for X$ otherwise you see this popup showing it is a fake chip every time you plug it in. If people buy something with fake components inside, it is the responsability of the seller / manufacturer of said device to solve it. If a responsible manufacturer discover some fake chips entered his line of production, he would remove said chips and improve his quality control. Consumers don’t care or even know what chip is in a product.
They have already covered their cost for the movie why should I have to PAY for it ehh???? They are providing a product at a price that they feel is competitive for the features, reliability and support they provide. You could also ask why does “Tag Heuer” charge so much for their watches? Because people that want a Tag want a Tag.
Not only this, but it also offers a driver exclusion list and also lets users schedule driver scans. Furthermore, to use this professional driver updating tool, you don’t need to collect information about the operating system or the device model number. Advanced Driver Updater does all that on its own. Once you install the product and run the scan, it automatically collects the required information and shows the correct driver update based on the operating system, versions, and model numbers. Some commentors have pointed out that FTDI has no obligation to produce drivers that work with counterfeit chips. While this stance does make some sense, the problem lies more in the fact that FTDI’s driver DOES supports counterfeit chips (if only well enough to screw with/brick them).
Once you’ve clicked on the version number, it will automatically download as a zip file in your chosen directory. The library is linked with your program in userspace, no kernel driver required. If you don’t know the model name or number, you can start to narrow your search down by choosing which category of Insignia device you have (such as Printer, Scanner, Video, Network, etc.).
If this is true, it is very unlikely you’re hit by this issue, unless your windows 7 PC was very behind on updates and you just happen to have the flaked driver. I now fixed this by leaving the PID at 0000 and ‘fixed’ the old drivers to work for this value. You then have to install the drivers manually , first for the bus then for the serial port.
Click OK. In the “Setup” | “Terminal” dialog, set “Transmit” to “CR+LF”, and check “Local echo”. Linux on Laptops – good place to go if you are running linux on a laptop and want to check compatibility or get hints for you particular laptop. The linux usb web site is the place to go for anything to do with usb and linux. Sourceforge FTDI SIO Project Page – this is the sourceforge page for this driver. Baudrate changes and BREAK setting are also tested.
