known issues and limitations (5.0) ----------------------------------
the drivers have a slower performance than the previous versions the drivers have a known issue with missing an rx_char event the drivers are not currently compatible with the vb mscomm control when using with hyperterminal, there is a problem with surprise removal the drivers can have problems loading if a previous device instance is unplugged and replugged when multiple devices are present
note: the above issues are being addressed currently and should be fixed in a later release of the vcp drivers. it is recommended to continue using the 4.40 drivers unless you have a specific reason to upgrade at this time.
他们并不建议现在就使用5.0版本...
不过5.0有这么个东东,driver now includes a serial enumeration filter driver.不知道对减少干扰有没有好处...
