Hi All,
I have developed a driver for USB-to-Serial bridge device. But system does not load standard mouse driver when a serial mouse is connected to USB-to-Serial bridge device.
Could any one give me pointer how to load a mouse driver for the mouse connected to USB-to-Serial bridge device?
Thanks & regards,
Anand

The key to this is the serenum protocol, see this link

my guess is that your usb->serial bridge is not fully implemented serial port, or if it is, it has timing issues which prevent the serial enumeration protocol from running successfully. You can easily test this out by open the com port in user mode and implement the protocol and reading the output from the port.

You can also build serenum.sys and see where it is failing.
