hi, I want to modify the serial number or PID/VID of my usb mass stroage disk.
I try it by an usb class filter driver to capture the
URB_FUNCTION_GET_DESCRIPTOR_FROM_DEVICE,then modify the data...
But,It seems useless!
how should I do? many thanks!

what side affect do you want your change to have? that the usb core not use
it for a unique ID or that usbstor uses your changed value ?

Add the filter which will just ignore the serial number by patching the
DEVICE_CAPABILITIES and resetting UniqueId bit.

Re: how to modify serial number of usb device by usb filter driver

that is too late. you need to filter the parent hub's query device
relations. you need to filter the entire usb bus since you don't know which
port you will be attached to. this is a very difficult task, you can't
really work around your broken hw this way

Re: how to modify serial number of usb device by usb filter driver

You are right...I had just follow the advice by Maxim S. Shatskih.
it still can't work :(

I will try to filter the entire bus...any advice?
or, Is there other way to make the two device work together?

Re: how to modify serial number of usb device by usb filter driver

By the way, the two devices (with identical pid/vid and serial number) work
well in Win XP, but not in Win 2k.
what's the difference?

Re: how to modify serial number of usb device by usb filter driver

you are proposing to write a bus filter driver. quite difficult to do and
completely undocumented and unsupported by microsoft.

Re: how to modify serial number of usb device by usb filter driver

the XP usb core tracks serial numbers and does not use the serial number as
a unique identifier on the bus
