Serial Port Devices Windows 7 and Vista driver for serial port adapter Applies to the Following Product: - Cyber Serial Dual Plus (JJ-P20212) Description: I need the Windows 7 and Vista driver for my PCI serial port adapter. The pf driver is intended for use with parallel port ATAPI disk devices. The most common devices in this category are PD drives and LS-120 drives. Traditionally, media for these devices are not partitioned. Consequently, the pf driver does not support partitioned media. This may be changed in a future version of the driver.

The USB (Universal Serial Bus) standard specifies two roles USB host and USB peripheral (also known as USB function, USB peripheral device or sometimes just USB device). The bus can only have one USB host connected all other devices need to be in USB peripheral mode. Most PCs support USB host mode exclusively. However, embedded systems often have multiple USB controller supporting host or peripheral roles or supporting both roles on a single controller (dual-role controller). The dual-role controllers often also support the OTG (On-The-Go) specification which defines a host negotiation protocol allowing two devices to negotiate for the role of the host.

On Colibri modules the client port (USBC) is usually connected to a dual-role capable controller. By default the port is in peripheral mode. If a USB Micro-B OTG cable is used (which connects the ID pin to ground) the circuit on the carrier board automatically enables driving +5V onto VBUS in order to provide power to USB devices as required by a host. On the other hand VBUS is also connected to the Colibri USBC_DET signal (usually via a diode) allowing driver software to monitor and subsequently change the role. On Apalis modules a full OTG port (USBO1) is provided which makes use of the OTG ID pin using the USBO1_ID signal to determine its role and additionally the VBUS pin using the USBO1_VBUS signal to determine the actual connection status thereof allowing suspending the USB complex if not connected.

On Linux USB peripheral mode is supported through the Gadget API. This API abstracts the USB peripheral controller hardware as well as offers hardware neutral routines which allow to implement USB functions (e.g. USB CDC ACM or RNDIS). Traditionally the USB function had to be chosen at Kernel compile time (e.g. g_ether). The Linux USB gadget drivers received increasingly more attention and have evolved over time, especially since Android appeared. The Android variant of the Linux kernel added functionality allowing easy switching between USB functions using sysfs. Later in Linux 3.10 a similar functionality also landed in the upstream kernel which now allows configuring USB gadgets through configfs (the USB Gadget ConfigFS). Depending on the Linux kernel version provided by our BSP a different level of USB peripheral functionality and API is available.

If your phone is connected to the USB Port of your PC, Disconnect it before running the installer you just downloaded. Click the downloaded.exe file. Select the language and click Next button to install LG Universal.

USB peripheral devices need a vendor and product identification. Toradex has its own vendor ID (0x1b67) and assigns a product ID for each Colibri and Apalis product which you as a customer can use too. The USB Product ID is the sum of an offset of 0x4000 and the hexadecimal representation of the product identifier, e.g. 0x4000 + 12 = 0x400c (the product identifier is the first 4 digits of the Toradex Product Number, e.g. 0012 for Colibri VF61 256MB IT V1.1B).

Some platforms need device dependent and certified drivers (e.g. CDC ACM for Microsoft Windows) even for standard USB classes. While it is possible to use the driver delivered with Windows a custom inf file still needs to be provided. For better out-of-the-box experience the standard images typically use the default Linux USB product/vendor ID (e.g. 1d6b:0104 Linux Foundation Multifunction Composite Gadget).

Drivers epilog printers. U-Boot's CONFIG_USB_DEVICE config symbol allows for U-Boot to provide USB peripheral mode support. With recent versions we successfully tested ums (User Mode Storage) and dfu (Device Firmware Upgrade). Both USB functions conform to standardized USB classes.

Since BSP V2.4 all modules use the same U-Boot version 2015.04. This common U-Boot version configures the USB peripheral device identification using the Toradex vendor ID and product ID.

The following exports the eMMC on SoMs with an eMMC or the SD card on the SoMs with raw NAND. Note that with CTRL+C you can abort the operation and regain control over U-Boot.

On the host connected to the SoM you will now see the following USB device. Assuming you have our regular BSP installed on an eMMC based SoM the following block devices will also appear and possibly mounted:

Note that ums currently can only export the user area of an eMMC but not its boot areas. This prevents you from updating the bootloader over this mechanism.

NXP/Freescale Vybrid/i.MX7/i.MX6ULL/i.MX6/i.MX8/i.MX8X based Modules

The NXP/Freescale Vybrid BSP (since V2.4 Beta 1) and the i.MX BSP (since V2.5 Beta 2) use the USB Gadget ConfigFS to configure the USB peripheral port.

The USB Gadget ConfigFS is a file system which allows to configure USB functions by using file system commands such as mkdir and creating/writing files. Typically the file system is mounted under /sys/kernel/config/. The official Linux kernel documentation has more information in Documentation/usb/gadget_configfs.txt on how to use the file system to enable USB functions. Matt Porter held a talk at ELC 2014 titled Kernel USB Gadget Configfs Interface cover the Gadget ConfigFS a bit more in depth.

The library libusbgx (or its predecessor libusbg) allows to use the USB Gadget ConfigFS through a C API. This can be useful if embedded software needs to dynamically control USB functions provided by a device. The library also provides two utilities called gadget-import and gadget-export. This utilities allow to export a hand-crafted USB Gadget to a schema file and reimport it.
The BSP provides a default schema specifying an RNDIS configurations (USB functions) under /etc/usbg/g1.schema. A systemd service called usbg.service uses gadget-import to import this schema on startup (see this commit libusbg: add updated version of USB gadget library which initially added the functionality, then providing an RNDIS and CDC ACM composite device).

To alter the schema, one can either create a completely new gadget schema, alter the existing gadget and reexport it, or alter the schema directly (for simple changes). Dh electronics gmbh driver download for windows 8.1.

This example shows how to create a completely new configuration., to create a Gadget configuration for the a single USB CDC (Communications Device Class) Ethernet (ECM).

First a new gadget needs to be created

Attention: If /sys/kernel/config/usb_gadget/ does not exist you need to load the libcomposite module: modprobe libcomposite

Then, one or multiple configurations can be assigned. A Gadget supporting multiple configurations (USB functions) is also known as a composite gadget. Note that depending on the operating system used on the USB host device, it might be problematic to use such configurations (see also Documentation/usb/gadget_multi.txt)

Functions can be created by creating a directory like functions/.
