What do you mean by “USB exit”? It’s not a term in common use.

Why? Write a upper filter to the Microsoft USB driver and block any new
arrivals. This is a fairly simple project for an advanced driver writer,
but not something a beginner would want to try to finish quickly.

wouldn’t it be easier to just set a security policy to disallow unloading
and loading of drivers?

I can think of solutions, both of which don’t really require new
software:
-
disable the usb controller in device manager or through setupdi (see
the devcon example). I think that enabling / disabling devices require
admin like rights so if the users aren’t admins this will work. -
change the service value in under
hklm.…\currentcontrolset\services<usb controller service> to null.sys
instead of the real binary. Again, only a user w/sufficient privs can
alter this value.
If your users have the privs required to change these values, you are
doomed b/c they can undo any driver solution you put into place.

You received several good ideas and the security of not allowing them to
install drivers may be the best. I am not sure if a USB device, such as a
hard driver or mass storage compliant flash memory reader, is plugged in and
will use standard Microsoft drivers that you can block it via security.
I write software for a living, whenever I can find work, so why would I give
it away?
Since jobs are so hard to find, why not just fire anyone who uses an
unauthorized device? I am sure after the first person is escorted out the
door by guards, all other employees will get the message. You can also
audit the computer to find any devices that have been introduced and
removed. The registry retains all that info.

So you only need to answer your own rephrased question:
how resolve/overcome the problem Windows 9x/ME ?

I can see a point, for example, in disallowing users to plug in CompactFlash

Um, If you want some usb device to work and other to not, I don’t have
an answer. Otherwise, you can replace the service on the device with
your own (that does nothing) or just disable the controller device node.
In win9x, there is no concept of security nor user rights so the user
can undo anything that you put in place.

I can think of solutions, both of which don’t really require new
software:
1) disable the usb controller in device manager or through setupdi (see
the devcon example). I think that enabling / disabling devices require
admin like rights so if the users aren’t admins this will work.
2) change the service value in under
hklm.…\currentcontrolset\services<usb controller service> to null.sys
instead of the real binary. Again, only a user w/sufficient privs can
alter this value.
If your users have the privs required to change these values, you are
doomed b/c they can undo any driver solution you put into place.

I have implemented a solution for this problem. I’m sorry but I don’t send
to you any piece of code because it is a part of a comercial product. In
any case, I can say that, in W9X, I’m filtering some system services
related to Configuration Manager while, in W2K/WXP, I filter PNP IRP’s
when a new device arrives the system.
Regards,
Jose Vicente.
