Notice
1. In order to achieve the USB 2.0 Speed for this Docking Station must be plugged in to
USB 2.0 Host and Windows 2000 or Windows XP. If this Docking Station is plugged
into USB 1.1 Host, will only have USB 1.1 Speed.
2. Some Mainboard may have its OWN driver for the USB 2.0 Host drive, please make
sure your Mainboard or PC manufacturer for update details.
3. In windows 98SE and ME, the Docking Station driver has two parts to working with
system, one is virtual COM port driver, and the other one is USB support driver.
Since we designed
Docking Station has not IRQ feature to avoid resource consume
(because IRQ is limited), and it want to follow USB spec that can hot plug/unplug, so
Docking Station of driver and hardware both can’t support device that is to operate with
IRQ feature, as we know, the older serial Keyboard and mouse are work with IRQ to
interrupt OS to service its requirement, that’s why
Docking Station can’t work in
Keyboard/Mouse.
Serial/Parallel Port Limitation for support serial Keyboard and Mouse
In Windows 98SE and ME, the Serial Port driver has two parts to working with system, one
is virtual COM port driver, and the other one is USB support driver.
Since we designed Serial/Parallel Port has not IRQ feature to avoid resource
consume (because IRQ is limited), and it want to follow USB spec that can hot
plug/unplug, so
Serial/Parallel Port of driver and hardware both can’t support
device that is to operate with IRQ feature, as we know, the older serial Keyboard
and mouse are work with IRQ to interrupt OS to service its requirement, that’s
why
Serial/Parallel Port can’t work in Keyboard/Mouse.
In Windows 2000/XP, Serial/Parallel Port driver is designed by Microsoft’s
WDM, and only have one driver that registry on port class, in this WDM driver, the
COM port driver is more close with HID interface, so,
Serial/Parallel Port driver
also have some feature near with HID, but because they are different class, so it
must has different in something.
We don’t know how mouse be made by a company, so we don’t know why some
mouse can run well but another couldn’t, we think it relatives with HID and COM.
In fact, we think that only has very, very few people use tradition serial
keyboard/mouse on PC, so the detail reason that why
Serial/Parallel Port has
issue with those device, because we haven’t not so many resource to analysis it,
so we let is a limitation on
Serial/Parallel Port .
