Hi,
I’m designing a disk class driver where the underlying hardware will be a
USB device (but not using the UAS protocol). I have an alternative
propriety protocol.
Now, the easiest way to use USB nowdays has gotta be KMDF. However, i
haven’t seem many (or any) examples of storport that use KMDF (or even
WDM) as the lower edge.
Is this even possible? Is there a more elegant way to do this?
Thanks,
Menachem
a virtual storport driver can theoretically use anything as its lower edge.
The examples generally use a network or file interface but certainly you
could implement a proprietary usb driver and have vstorport use that.

You’re suggesting an additional usb kdmf. I’m thinking of doing it on the
same driver. Would it work?

Mark is pointing out that a Storport driver may only use the Storport API’s. There is no mechanism for accessing a USB device this way.
However, you may create a virtual storport driver instead. These drivers do not have the Storport only restriction. You can create and send requests to the USB stack as needed to access your device. Your driver will process Storport requests like BuildIo or StartIo by reformatting the SCSI request into whatever it is your device processes and then sending it to USB stack.
In this model, you can use KMDF in miniport mode and use the USB io targets.

Mark is pointing out that a Storport driver may only use the Storport API’s. There is no mechanism for accessing a USB device this way.
However, you may create a virtual storport driver instead. These drivers do not have the Storport only restriction. You can create and send requests to the USB stack as needed to access your device. Your driver will process Storport requests like BuildIo or StartIo by reformatting the SCSI request into whatever it is your device processes and then sending it to USB stack.

Oh yeah, I tried them too. Then I read about “safe links” which is (naturally) some sort of tracking system under the guise of “filtering” and “security”:
“Your safe links policy can be enabled to log which recipients are following links that have been protected by safe links. If tracking URLs is also enabled, this information can be found in the Exchange Admin Center by choosing mail flow > URL trace. You can sort the URL trace report by date range, recipients, and specific URLs…”
That shit is just plain scary. Your EXCHANGE SERVER tracking the links you click that Re embedded in your email? Yikes.

Sure, why not? I mean, it’s nothing new:
“Windows 10 automatically sends parents detailed dossier of their children’s internet history and computer use”
“Next is a rather nebulous entry: “Let apps use your advertising ID for experiences across apps.” What this sentence doesn’t quite explain is that Windows 10 generates a unique advertising ID for each user. If this option is enabled, it allows app developers and ad networks to profile you using that ID and serve you ads based on how you use your PC.”
“Microsoft Says It Cannot Stop Windows 10 From Spying On You, Doesn?t Think You Should Be Concerned”
And of course, Wi-Fi Sense…
I disabled Windows Update about a week ago when I heard there was forced, unblockable Win10 downloads occurring. Kind of funny when you think about it:
1995: People lining up outside stores at midnight to pay for Windows 95.
2015: Forcing people to take Windows 10 for free.
