    Hello all,

    Recently I purchase USB to Serial cable (CH340) . I did not found drivers for Windows 7. I want to communicate my target board through Serial cable. Please help me in getting drivers for Windows 7 / 64-bit

    Thanks in advance.

    For many of these, Win-7 will recognize it automatically and load drivers with no further to-do. Some off-brand stuff may come with its own driver CD to load. You should know that there is a lot of junk/knock-off/counterfeit USB-serial stuff out there that doesn't work very well. Even if you get a driver to work, they frequently have comms problems.

    Personally, I'd return it and get something better. Air-link, IOgear, SIIG makes good stuff. Other brands may be OK as well if they use the FTDI / prolific chipsets but its hard to know.. There are some long threads here discussing the problem.

    After messing around with a few bummers, I finally went with a PCI-E 4X serial board from SIIG. Works perfectly all the time with Win7-64 Pro.
