DriverKit USB Transport to support multiple devices with different Vendor IDs

I have two different USB devices with different vendor IDs I would like to connect to. I submitted two separate requests for the com.apple.developer.driverkit.transport.usb entitlement for each vendor ID. However I am noticing the provisioning profile only has one of the vendor IDs.

Yes. You can basically think of each request as "I would like to create a DEXT that supports <this>", where <this> can basically be an arbitrarily complicated set of match criteria.

How do I submit a request for the USB Transport entitlement to support more than one vendor ID? I'm new to writing a DriverKit driver, so is this even possible?

You can do this by submitting an entitlement request saying that you want a profile that supports multiple vendor IDs. However, keep in mind that you can also ship multiple DEXTs in the same app, so I would only do this if the same DEXT is supporting multiple devices or you're creating a "complex" DEXT where different parts of the driver stack need to directly interact.

Kevin,

Thank you for your response. My team and I would prefer going down the path for one DEXT supporting multiple devices as it is the design choice we like the most.

With that being said, how would I create one entitlement request for the USB Transport for two vendor IDs when the form only accepts one?

Write up what you need and include it in the "Describe" section.

Hello Kevin ( @DTS Engineer ),

I have submitted a entitlement request for multiple vendor ids as you instructed but I am always getting back an entitlement for only one vendor ID. I have a made a feedback assistant: FB16085048

Please let me know if you need more information.

I have the same problem. Whenever I submit the request I get back what seems to be an automated response saying that I can now use my entitlement.

It doesn't seem like anyone actually looks at the description.
