Takes a 0x10-byte input struct and a type-0x6 output buffer, returns an output u32 total_entries.
Takes an [[#UsbHsInterfaceFilter]] and a type-0x6 output buffer, returns an output u32 total_entries.
The output buffer contains an array of [[#UsbHsInterface]].

Takes an input u8 and a 0x10-byte struct, and returns an output handle. The input value must be 0..2. This is used as an index in a table.
Takes an input u8 and an [[#UsbHsInterfaceFilter]], and returns an output handle. The input value must be 0..2. This is used as an index in a table.
The struct is located at +2 from the u8 in IPC rawdata. This struct is the same as the one used for [[#QueryAvailableInterfaces]].
The struct is located at +2 from the u8 in IPC rawdata.
When signaled, this indicates that the user-process should use [[#QueryAvailableInterfaces]] and [[#AcquireUsbIf]] with the output interfaces (and the rest of interface setup).

This is a 0x10-byte struct (unofficial name).
This is used to filter [[#UsbHsInterface]], the query commands will only return the interface when these checks pass. When a bit in Flags is set, the associated descriptor field and the field in this struct are compared, on mismatch the interface will be filtered out. Passing Flags=0 is equivalent to disabling filtering since none of these checks will run.
Flags bits 0..1 use usb_device_descriptor, while 7..9 use usb_interface_descriptor.
Flags bits:
* 0: idVendor
* 1: idProduct
* 7: bInterfaceClass
* 8: bInterfaceSubClass
* 9: bInterfaceProtocol
HID-sysmodule uses the following for the input struct: <code>80 00 00 00 00 00 00 00 00 00 00 00 00 03 00 00</code>
