The Linux USB gadget sub-system supports USB device functionality, including USB networking.
Go to the device manager and click on the base system device needing the driver. Click on the driver tab. Click in Update Driver. Select the Browse my computer for driver software option and browse to the driver folder that was created when you ran the file. That folder will be located in C: SWSetup sp74783. The card is also detected successfully as a PIC Hardware as a thunderbolt and USB 3.1 device. The USB 3.1 / USB-C port on the card worked successfully to connect to and transfer data to.

Build USB Ethernet network gadget driver
The USB Ethernet network gadget driver caused the device to appear to be a USB network dongle when connected to a host computer. Generally it is best to build USB gadget drivers as modules instead of building them into the kernel so you can unload one and load another.
If you want the target to mount a host PC directory using NFS, then also enable NFS mount support in busybox:
Build the SDK and install the new images to the target hardware.
Load USB Ethernet network gadget driver
After booting the target hardware to a shell prompt, run:
and you should see output similar to:
You can then verify the usb0 network interface exists:
with output similar to:
Connect device to host PC
Before connecting the target device to the host PC, watch the syslog, by running the following command on the host PC:
Connect the USB cable between the target device and the host PC. The messages file on the host PC should indicate the new USB device was detected.
On the host you can verify the new usb0 interface exists by running:
with the output being similar to:
When you connect the cable, in the target device console, you should see:
Assigning IP addresses
For this simple example, fixed IP addresses are assigned to the both the host PC USB network interface and the target device USB network interface.
On the host
with an entry from the route output that looks like
On the target device
with the route showing the default gateway is using usb0
Verifying network connectivity
On the target device, ping the host PC:
On the host PC, verify the number of packet sent and received is not zero
Look at the values of RX packets: and TX packets:.
Bridging host PC to allow device to reach the Internet
If your host PC is connected to the Internet (through WiFi or Ethernet), then you can allow the target device to share the host PC's Internet connection. The following shows how to enable, test, and disable. It only works if your host PC doesn't have a firewall enable. There is a lot of information on how the Internet giving more detailed explanation.
On the host PC:
And then for reasons I don't fully undestand, I had to configure usb0 on the host again:
On the target device:
To disable forwarding network packets on your host PC:
Configuring a DNS name server
If you need to resolve DNS names, you can configure your target hardware to use Google's DNS server via:
and you can test that names get resolved by pinging some computer on the Internet:
Mounting NFS file system
If you have already enabled NFS share of your development directory target file system, $DEVDIR/fs/fs, then you can easily mount the file system on the target. This is different than a root NFS mount. With a root NFS mount, networking has to be available when the kernel is booting. With a normal (non root file system) NFS mount, you are simply mounting a shared directory somewhere in the target device's file system.
First verify you build the target file system kernel with NFS enabled: Download atarimax driver pc.

Wireshark
Biomed Medical Device
Wireshark is your friend. Run wireshark on your host PC monitoring the usb0 interface and you don't need any packet filters. If something isn't working, you will see the last packet that was sent and not responded to. That will give you a big hint as to where to start looking for the problem.
NFS mount failed reason given by server: Permission denied
If you see a message like
and you know you have root NFS working, the cause is due to a different sub-LAN address being used. On your host PC, you need to make sure the 10.0.1.* sub-LAN is exported. Run the following commands to export you home directory to all computers on this sub-LAN:
Generally there's no difference between Alpine Linux USB bootable installation medium and installed system in diskless or run-from-ram installation mode. The only difference is that after finished installation modified files have to be saved somewhere, hence Alpine Local Backup. Thus this document describes how to proceed to end with an installation of a system in diskless or run-from-ram installation mode with locally saved modifications.
This process applies to Alpine Linux 1.9.0 or later.

Requirements
In order to follow this document, you will need:
- Alpine Linux CD-ROM (Download a .iso file containing an Alpine release.)
- A USB drive (flash, external HD, card reader, etc.)
Copy Alpine to USB stick
The following part describes various ways how to create bootable USB stick with Alpine Linux.
Clone ISO image content to USB stick (Alpine Linux from 3.3.0 and later)
From Alpine Linux 3.3.0, the generated ISO's are a hybridISO, which means they contain a valid MBR and can be raw copied directly to the USB stick, Hard Drive (If you really know what you're doing), or burnt to a CD/DVD.
If the USB stick is in a Unix/Linux/OSX system, you will need to find out what the USB device is. There are various utilities to determine the device name (e.g. /dev/sdx) for your USB device. One way is:
If it is still unclear which is your USB's device name, in Linux you could try sudo lsblk -a
; or use parted (sudo parted -l
).
Then, in order to dd the iso, ensure that your usb drive is not mounted, as various desktop environments automatically mount usb pen drives:
Next, change to the directory where your Alpine .iso file is located, for example:
Alpine Biomed Usb Devices Driver Download
Then you can use dd to copy the iso to it. Change alpine.iso
in the following command to the name of your .iso file; and change /dev/sdx
to the name of your pen drive's device name. The following command may take a few minutes to execute:
Copy ISO content to USB stick as individual files
The following procesure is for Alpine Linux distribution itself, if you are using other Linux distro or other operating system you should know the best how to install syslinux and where mbr.bin file is located on your filesystem.
- If you created a new partition above, format the USB stick with a FAT32 filesystem (replacing sda with your USB stick name):
apk add dosfstools
mkdosfs -F32 /dev/sda1
- Install syslinux and MBR (replacing sda with your USB stick name):
apk add syslinux
dd if=/usr/share/syslinux/mbr.bin of=/dev/sda
syslinux /dev/sda1
- Copy the files to the USB stick (replacing sda with your USB stick name):
mkdir -p /media/sda1mount -t vfat /dev/sda1 /media/sda1cd /media/cdromcp -a .alpine-release * /media/sda1/umount /media/sda1
- (Optional) Remove any apkovl files that were transfered as part of the copy process. This should be done if you wish to have a fresh install. Replace sda with your USB stick name)
mount -t vfat /dev/sda1 /media/sda1rm /media/sda1/*.apkovl.tar.gzumount /media/sda1
Create bootable USB stick from ISO on Windows
Additionally to the method above for Linux systems, there is also the Rufus program available, which allows writing such bootable USB flash drives under Windows.
- Partition scheme:
MBR
- Target system:
BIOS or UEFI
- File system:
FAT32
- Cluster size:
4096 bytes (default)
Troubleshooting
Wrong Device Name
If you cannot boot from the USB stick and you see something like:
then it is likely that the device name in syslinux.cfg is wrong. You should replace the device name in this line:
with the proper device name.
- For boot from USB, the device name should be 'usbdisk' (as shown above)
- For other options, you can run
cat /proc/partitions
to see the available disks (i.e. 'sda' or 'sdb')
Non-FAT32 Filesystems
When your USB stick is formatted with a filesystem other than FAT32, you might have to specify the necessary filesystem modules in the boot parameters.
To do so, mount the USB stick and change the syslinux.cfg file line from
to
in the case of an ext3 formatted partition. A similar procedure might apply to other filesystems (if they are supported by syslinux and the Alpine Linux kernel).
Finishing installation
After one has booted previously created Alpine Linux bootable USB medium, to finish the installation one has to prepare USB stick to hold local customization and run setup-alpine.
First let's find out where is our just booted USB media mounted, the location could vary.
Create local directory on USB media to hold local APK cache (see APK Local Cache for details).
Now run setup-aplpine and proceed till a question about local disk selection - in diskless mode we won't use any disk (ie. our bootable media files is basically untouched) and we are going to use sda1 to hold our system customization.
After the installer finished you can see how many files are created/modified by the installer and which need to be preserved:
Thus all our customization is saved into foo.apkovl.tar.gz compressed tarball on the USB stick itself.
Troubleshooting
Slow USB Devices
Specifying the 'waitusb=X' option at the end of the syslinux.cfg line might help with certain USB devices that take a bit longer to register. X stands for the amount of seconds kernel will wait before looking for the installation media.
