Ch340Ser

Post by Scott99 »

Hello, I recently acquired a CH340SER USB to serial converter and I'm currently in need of the driver for it. I've been searching for the driver online but unfortunately, I haven't had any luck in finding a reliable source. I've visited the manufacturer's website, checked various driver databases, and even tried looking in forums dedicated to device drivers, but to no avail. It seems that the driver for this specific device is quite elusive. If anyone here happens to have a direct link to the CH340SER driver or any suggestions on where I could find it, I would greatly appreciate your assistance. Thank you in advance!
