Struct LegacyUsbManager 

pub struct LegacyUsbManager {
    metadata: DeviceMetadata,
    platform: Platform,
}

USB mass storage manager for legacy platforms.

This implementation loads kernel modules to enable USB mass storage on older Kobo devices. For each platform it first tries g_mass_storage.ko; if that is absent it falls back to g_file_storage.ko with platform-specific dependencies:

• mx6sll-ntx, mx6ull-ntx: loads configfs, libcomposite, usb_f_mass_storage deps
• mx6sl-ntx: no extra dependencies (arcotg_udc is built into the kernel)
• other platforms: loads arcotg_udc before g_file_storage

Fields

metadata: DeviceMetadata

platform: Platform

Implementations

impl LegacyUsbManager

pub fn new(metadata: DeviceMetadata, platform: Platform) -> Self

Creates a new legacy USB manager.

Accepts the platform detected by the caller. No USB operations are performed until enable is called.

fn drivers_path(&self) -> String

fn has_g_mass_storage(&self) -> bool

fn build_file_param(&self) -> String

Builds the file= parameter value for insmod, including the SD card partition when one is present (matching the original usb-enable.sh behavior).

fn build_file_storage_params(&self) -> Vec<String>

fn load_g_mass_storage(&self) -> Result<(), UsbError>

fn load_g_file_storage(&self) -> Result<(), UsbError>

fn load_usb_module(&self) -> Result<(), UsbError>
