We ship an iPadOS app with an embedded USBDriverKit extension that drives Citizen/DNP dye-sub photo printers. It works: on a development-provisioned iPad the dext registers, matches, opens its user client and prints, verified on two units in hand (DNP DS-RX1 0x1343:0x0005, DNP QW410 0x1452:0x9201). The extension declares twelve IOKitPersonalities, each pinned to one exact idVendor/idProduct pair plus bConfigurationValue and bInterfaceNumber. Those twelve span two vendor IDs — 4931 (0x1343, Citizen Systems) and 5202 (0x1452, Dai Nippon Printing) — because the same printer families ship Citizen-badged on one and DNP-badged on the other. We have one USB Transport – VendorID request per vendor ID, both currently Submitted. Thread 842748 already answered the scope question for us, so I'm not asking that one: at twelve devices we read vendor-level as the right ask rather than twelve VendorID+ProductID requests, and we've kept the personalities narrow so the entitlement is a ceiling rather than what actually matches. Please correct me if that's the wrong reading for two vendor IDs rather than one. My actual question is about a mistake in one of the submissions. The older request also asked for UserClient Access, which we now understand is macOS-only (com.apple.developer.driverkit.userclient-access lists DRIVER_KIT and MAC_OS, not IOS). We don't need it — on iPadOS the app opens the dext's user client with com.apple.developer.driverkit.communicates-with-drivers, which needs no approval. Does an inapplicable entitlement on a submitted request need to be formally withdrawn, or is it simply ignored during review? I'd rather not leave a macOS-only entitlement sitting on an iPadOS request if that's something a reviewer has to resolve. If it does need correcting, what's the mechanism? Re-filing would create a third request, and I'd rather not muddy the queue. (Developer Support told me request handling is outside their scope, which is what brings me here.) Is there any way to indicate that two requests belong to one driver extension and are only useful together? Happy to post the Info.plist personalities or the dext's entitlements if useful. Thank you.
