!usb3kd.ucx_controller
Perintah !usb3kd.ucx_controller menampilkan informasi tentang pengontrol host USB 3.0. Tampilan didasarkan pada struktur data yang dikelola oleh driver ekstensi pengontrol host USB (Versi Ucx.sys).
!usb3kd.ucx_controller UcxControllerPrivContext
Parameter
UcxControllerPrivContext
Alamat struktur _UCXCONTROLLER_PRIVCONTEXT yang mewakili pengontrol.
DLL
Usb3kd.dll
Keterangan
Driver ekstensi pengontrol host USB (Versi Ucx.sys) menyediakan lapisan abstraksi antara driver hub USB 3.0 dan driver pengontrol host USB 3.0. Driver ekstensi memiliki representasi sendiri dari pengontrol host, perangkat, dan titik akhir. Output perintah !ucx_controller didasarkan pada struktur data yang dikelola oleh driver ekstensi. Untuk informasi selengkapnya tentang driver ekstensi pengontrol host USB dan driver pengontrol host USB 3.0, lihat Arsitektur Usb Driver Stack.
Contoh
Untuk mendapatkan alamat konteks privat pengontrol UCX, lihat output perintah !ucx_controller_list. Dalam contoh berikut, alamat konteks privat 0xfffffa80052da050.
