Heretic's questions

Os hubs integrados são detectados como hubs raiz USB ou dispositivos externos?

  • 5

Conectei um hub onboard ao meu microprocessador. O hub onboard é USB2514B e o microprocessador é um STM32MP1.

Posso especificar a conexão com o hub integrado usando OHCI (Open Host Controller Interface), mas então recebo mensagens de erro.

usb 1-1.4: device descriptor read/64, error -62
usb 1-1-port4: unable to enumerate USB device

Isso significa que o OHCI (USB 1.1) não pode se comunicar com o USB2514B, que requer a especificação USB 2.0.

Mas se eu conectar meu hub integrado usando EHCI (Enhanced Host Controller Interface), que é USB 2.0.

Então no Linux não terei erros sobre nenhuma descrição de dispositivo. O meu lsusbfica assim:

>> lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Pergunta:

Isso significa que este 1d6b:0002é o hub USB2514B ou que é o USB interno do processador?

Estou procurando uma maneira de confirmar se tenho conexão com meu USB2514B ou se lsusbsó mostra minha conexão USB interna do processador.

NOTA: Este hub USB integrado não requer nenhuma interface de comunicação externa, como SMDbus, I2C ou outra. Apenas conexão USB simples + configuração de árvore de dispositivos Linux.

&usbh_ehci{
    status = "okay";

    /* USER CODE BEGIN usbh_ehci */
    phys = <&usbphyc_port1>;
    #address-cells = <1>;
    #size-cells = <0>;
    /* onboard HUB */
    hub@1 {
        compatible = "usb424,2514";
        reg = <1>;
        vdd-supply = <&v3v3>;
    };
    /* USER CODE END usbh_ehci */
};

&usbh_ohci{
    status = "disabled";
};

Como habilito uma porta de servidor SSH no Raspian? (Raspberry Pi Debian)

  • 2

Vou configurar um Raspberry Pi B+ sem teclado, mouse e tela. Vou usar apenas o PuTTy (MS-windows, cliente ssh) e um cabo ethernet entre meu Raspberry Pi e meu roteador.

O disco rígido do Raspberry Pi é um cartão SD e no cartão SD há um arquivo chamado "cmdline". Eu abro o arquivo "cmdline" e adicionei "ip=192.168.1.2" para definir o endereço IP no Raspberry Pi.

Tutorial: https://youtu.be/Ioih6MHNNqc?t=1m1s

Então escrevi este comando:

nmap -F 192.168.1.1-100

Ele verifica todos os endereços IP de 192.168.1.1 a 192.168.1.100

Então eu encontrei 192.168.1.2

Nmap scan report for 192.168.1.2
Host is up (0.0084s latency).
All 100 scanned ports on 192.168.1.2 are closed

Mas as portas estão fechadas. Como posso abrir portas? Posso fazer isso no arquivo "cmdline"?

ssh raspberry-pi
