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...
