Hi all
I needed some solution for downloading firmware on to a USB device. Our
Device
will have different VID and PID depending on the client and different
drivers will be loaded for them . We need to download the firmware updates
as and when they come . Before downloading the firmware , we need to send a
Vendor specific command to put the device into Boot mode . For doing that we
need to uninstall what ever driver was loaded on that VID and PID , and then
load our firmware upgrade driver . After this we can send vendor specific
command and then download our firmware to the device . I am looking for a
solution with out disturbing the previous installation , Is there any way to
send a Vendor specific commmand directly with out depending on the driver
what is loaded before ? Once the device is put into Boot mode , rest of the
job is taken care with a known VID and PID .
One solution what I thought is put the System into Diagnostic mode , and
send Vendor specific mode to put the device into Boot mode and then later on
use our VID and PID to do updating the firmware . But that option is not
implemented in XP anymore I believe . So I am looking for an option which
can work on both W2K and WXP machines.
Any ideas ?
Thanks in advance
