Я хотел бы знать, поддерживает ли мой настольный компьютер USB 3.0
, но из вывода ниже это кажется маловероятным.
Я получаю следующий вывод lspci
:
root@liv-HP-Compaq-dc7900:/home/liv# lspci -v | grep -i usb

00:1d.7 USB controller: Intel Corporation 82801JD/DO (ICH10 Family) USB2 EHCI Controller #1 (rev 02) (prog-if 20 [EHCI])
И из lsusb
:

После всех портов USB, определенных как USB 1.0, а не USB 2.0 , я также публикую вывод lsusb -t
:

Я правильно понимаю, что только два слота поддерживают USB 2.0? И если да, то как я могу точно определить, какой физический разъем поддерживает USB 2.0?
USB3
контроллер на настольный компьютер?
