Hello experts,
here is the question on CE 4.1.
The scenarion in short is this. A customer has Windows CE
4.1 based device with USB port. The image we build for
them contains all drivers to support that port.
Customer conencts a USB printer to this USB port. Then
after a few seconds CE creates a virtual LPT2: port for
this USB printer. Customer then uses a control panel and
adds a new printer, as a parallel printer connected to
LTP2: port. And then saves settings into persistent
registry on flash disk. All works fine so far. Good !
Now customer turns the power off on the device. The USB
printer is still connected. Then next day customer turns
power on back on the devices and it boots up into CE.
However, it was found that LPT2: virtual port isn't
created !
Further, it was found that if a customer disconnects a USB
printer and then reconnects it back, then, after a few
seconds CE does create back again the virtual LPT2: port
for this printer.
My question is that : how do we ask CE to create virtual
LPT2: on startup, if a USB printer is detected connected
and up ? Is that possible at all or not - I cannot get
definite information from the documentation. We need to
know this to tell customer that, say, USB printers aren't
supported after reboot or so.
PS. Windows CE 4.1, enterprise web pad-like application,
has control panel. Device has built-in one parallel port
and one USB port.
Sincerely
Sergei
