This is "nn::usb::hs::IClientRootSession".
[7.0.0+] usb:hs:a opens an nn::usb::hs::IClientRootSession, but sets an "isSystemClient" field in the object (and in interfaces/eps opened by the session) to false.

No input, returns an output event handle with autoclear disabled.
When signaled, this indicates that the user-process should use [[#QueryAcquiredInterfaces]] and cleanup state for interfaces which were already initialized with a matching ID in [[#UsbHsInterface]] +0x0. When total_entries is less than 1, this indicates that cleanup should be done for all currently open interfaces.

Takes an input u32 and a type-0x6 output buffer, returns an [[#IClientIfSession]].
Takes an input u32 and a type-0x6 output buffer, returns an [[#IClientIfSession]]. On [3.0.0+] this takes an additional type-0x6 output buffer, before the original buffer. On [3.0.0+] the first buffer is 0x70-bytes, while the second one is 0x1B8. The user-process has the second buffer address immediately after the first one, which allows getting a complete [[#UsbHsInterface]].
The input u32 is from the u32 at entry+0 from the associated [[#QueryAvailableInterfaces]] output entry. User-processes use size 0x1B8 for the output buffer. The output buffer contains the first 0x1B8-bytes from [[#UsbHsInterface]].

This returns an error if the interface was already acquired by another process.

Takes an input u32 and a type-0x6 ([3.0.0+] type-0x22) output buffer, returns an output u32 '''count'''.
The input u32 specifies the total number of entries to read, this must fit within the specified buffer size. The output u32 is the total actual output entries.

==== PostBufferMultiAsync ====
Unofficial name.
Takes 3 input u32s ('''urbCount''', '''unk1''', and '''unk2'''), an input u64 '''buffer''' and u64 '''unk''', and a type-0x5 ([3.0.0+] type-0x21) input buffer, returns an output u32 '''xferId'''.
Where '''unk''' is the same as [[#PostBufferAsync_2|#PostBufferAsync]].
This uses the same func internally as [[#PostBufferAsync_2|#PostBufferAsync]] except multiple urbs are specified by the user: the input buffer contains an array of u32s for the size of each urb, where '''urbCount''' is the total number of entries in this array. With [[#PostBufferAsync_2|#PostBufferAsync]] the last 2 params passed to the internal func are hard-coded to 0, while with this command it's '''unk1''' and '''unk2'''.

This is used to filter [[#UsbHsInterface]], the query commands will only return the interface when these checks pass. This is also used for events with [[#CreateInterfaceAvailableEvent]]. 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.

Passing Flags=0 is equivalent to disabling filtering since none of these checks will run.
[7.0.0+]: The filter struct has to be unique, it can't match any existing filter structs used by [[#CreateInterfaceAvailableEvent]] (including other processes). Hence, Flags has to be non-zero. When initialized with usb:hs:a and VID and/or PID filtering is enabled, the VID/PID will be checked [[#HidGamepad]], with an error being throw if a matching device is found with quirk "ApplicationBlacklist" ([[#usb:qdb|usb:qdb]] cmd1 is used internally for this with bcdDevice=0).
Flags bits 0..6 use usb_device_descriptor, while 7..9 use usb_interface_descriptor. Support for bits 2..6 and the associated fields was added with [6.0.0+].

== Cmd0 ==
No input/output, takes a type-0x5 input buffer.
This loads data for [[#HidGamepad]] with the input .json.
== Cmd1 ==
Takes 6-bytes of input (u16s '''vid''', '''pid''', '''bcdDevice''') and a type-0x5 input buffer, returns an output u8 bool indicating success.
Locates an entry in the [[#HidGamepad]] state with the input u16s, and checks for a '''quirks''' array entry where '''name''' matches the input buffer string. Returns 1 when found, 0 otherwise.

With [7.0.0+] usb-sysmodule now has .json data embedded in the codebin.
This contains a list of USB devices' VID/PID, with the following structure:
[
{
"vid" : "<VID>",
"pid" : "<PID>",
"quirks" : [
{
"name" : "<string>" //The .json has the following for <string> for various devices: "HidGamepadWhitelist", "ApplicationBlacklist", and "NoClearHaltOnEpInit".
}
//There can be multiple entries here.
]
