Saya mencoba menghubungkan USB 3.0 pen drive menggunakan kabel OTG dengan board saya. Tetapi selalu terhubung dalam mode Kecepatan Tinggi dan tidak dalam mode Kecepatan Super. Saya menggunakan android marshmellow sebagai sistem operasi.
Di bawah ini adalah log saya ketika terhubung pen drive menggunakan kabel otg di usb 3.0.

Saya ingin menggunakan pen drive saya dalam mode SuperSpeed. Driver usb 3.0 saya adalah dwc3 jadi apakah ada perubahan pada driver atau file dts diperlukan untuk ini?
