USBD_DEVICE_INFORMATION

構造体

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

フィールド

フィールド型サイズx64x86説明
OffsetNextDWORD4+0+0次のデバイス情報構造体への相対オフセットを示す。
UsbdDeviceHandlevoid*8/4+8+4USBDが管理するデバイスハンドルへのポインタ。
DeviceDescriptorUSB_DEVICE_DESCRIPTOR18+16+8このデバイスのデバイスディスクリプタを格納する。

HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。
