Windows Subsystem for Linux WSL currently has very limited support for USB devices; it only supports accessing storage and serial pass-through devices. The following describes the steps to accomplish this. We'll be using Ubuntu If you're using a different Linux distribution, please consult its manual for installing and configuring an SSH server.

You don't have to use an OpenSSH server; if you prefer a different sever, just make sure it's properly supported in WSL with the "publickey" user authentication and SSH agent forwarding.

SSH agent forwarding allows you to use locally stored private keys for user authentication on intermediate servers. So you don't have to manually run commands or select menus to use your YubiKey; just plug it in and you're ready! Please note that the SSH agent forwarding in Token2Shell is a global feature that affects all sessions. You should use the following format for starting a session:. When the path to the Address Book entry created in Step 3 is " wsl-shell ", your command line should be:.

If SSH agent forwarding is correctly enabled in Token2Shell and your OpenSSH server on WSL is also properly configured to accept such request, you should be able to notice the " Enabled forwardings: authentication agent " status message on Token2Shell terminal screen. If you've decided to use a different folder path, please make adjustments accordingly in the next steps.

You can directly launch Token2Shell without those files. However, we're using them in order to simplify managing the commands and to hide the Command Prompt window that pops up whenever Windows commands are executed. When your password for WSL is ' ' and the path to the Address Book entry created in Step 3 is "wsl-shell", your batch file should be:. Please note that the above VBScript automatically attaches the ". You can now double-click the shortcut and start using your YubiKey for SSH public key authentication.

This blog post will describe how to use this feature and the work that was involved in exposing this functionality within WSL. By default init will populate this mapping using the mknod system call. Alternate mknod mappings can be created at runtime if needed. Since pty, tty, and ttyS share a terminal library code base, ttyS will behave similarly but also support the following termios settings which are simply mapped to Windows serial driver ioctls:. Figure 1. Please note that some serial drivers have known bugs.

The following areas are known to not work. We are tracking updates to future Windows Insider builds to address them. Please let us know on our Github about the specific serial scenarios that you are trying. Your feedback helps us prioritize what we should focus on next. Skip to main content.

Not all serial programs have the same behavior. Optionally check your current serial settings before updating.

Sign in to your account. Thanks for the feedback. Also, please also make any feature requests on our User Voice Page and help us prioritize. Unfortunately I can't give an ETA on this one. We know there is a desire to be able to access block devices from WSL but it is not terribly high on our priority list at the moment.

As sunilmut points out, the best thing to do here would be to add something to our User Voice page. Little secret, one thing that always helps the requests there is explaining the actual scenario you're looking to enable. It's in the nature of the thing that it is going to be served a pre-assembled abstracted filesystem.

Loading up something like dd while Windows mounts the disk in non-raw mode seems like it could be a problem, and this kind of thing seems to require effectively writing hardware drivers that negotiate hardware access between WSL and WSWin What is interesting to me is to hear what people want to do with these types of features.

The users of this forum often surprise me with their creativity and the more information we get the better. I have found that it never hurts to at least hear someone out. If something is compelling enough, and enough people want it, then we should at least look into feasibility and see where we may be able to fit it into plans. There is a high risk of corruption if a peripheral is already mounted :. I agree that it should be restricted to disks not already mounted.

But there would be need of something similar anyway to support access to disks like in the original question by OP. The first thing would be the extension of WSL's ability to mount different partition types in general, maybe with a way to query the NT kernel about "FS capabilities" which I suspect already exists, but probably does not exist with information about Linux FS feature support.

Then you would also need to write a kernel-mode driver or maybe somehow use FUSE? The first thing might be within the scope of WSL. The second probably isn't. At least fuse will be great.

This allows me to manages the fileystems of embedded devices runing linux directly for example I can run something like mkfs. Would it be possible to have the same feature on Windows subsystem for Linux? That is, getting a raw access in the kiss way. Am I understanding properly that even if MS found a way to allow the subsystem direct device access, standard linux filesystem kernel modules would not be usable with the subsystem's customized kernel? I was hoping we could mount the foreign filesystems which windows does not support otherwise and then export them with smbd - like it was possible to do with the old colinux project - but I guess this is too far off into the future for now.

If fuse support in LXSS is easier to implement, being a single thing as opposed to the various possible linux kernel filesystem drivers, it could be pretty great - even though core linux filesystems that have kernel modules don't seem to have fuse drivers yet because there was never any need for them, they can probably be developed once there is a use-case for them in LXSS.

Yes, as it's not a real kernel, filesystems included from linux kernel will not be usable or MS have to rewrite them. LXSS does not have a kernel and integrating linux kernel modules with the Windows security-model would be really difficult.

One use would be to mount micropython devices so that you can copy. That is specifically in the case of fat32 and ntfs removable media. My use for such devices is to be able to use tools like cdparanoia and abcde so that I can rip my audio cds directly in Windows vs.

Or implement that "other" popular request.This architecture will be available in the 'Virtual Machine Platform' optional component. This optional component will be available on all SKUs.

You can expect to see more details about this experience soon as we get closer to the WSL 2 release. We currently have no plans to deprecate WSL 1. You can learn more about VirtualBox's changes here and VMware's changes here. We are investigating ways to help resolve this issue.

This lets applications use the Hyper-V architecture for their emulation such as the Google Android Emulatorand VirtualBox 6 and above which are both now compatible with Hyper-V. In initial releases of WSL 2 hardware access support will be limited, e.

However, adding better device support is high on our backlog, as this opens many more use cases for developers that wish to interact with these devices.

In the meantime, you can always use WSL 1 which has serial port access. Yes, in general networking applications will be faster and work better since we have full system call compatibility.

However, the new architecture uses virtualized networking components. This means that in initial preview builds WSL 2 will behave more similarly to a virtual machine, e.

Windows Subsystem for Linux 2 (WSL 2) is here

We expect to add improvements as quickly as we are able to, such as accessing all networking apps from Linux or Windows using localhost. We will be posting more details about our networking story and improvements as we approach the release of WSL 2. You need to make sure that the virtual machine has nested virtualization enabled. This can be enabled in your parent Hyper-V host by running the following command in a PowerShell window with Administrator privileges:.

WSL 2 supports the same wsl. This means that any configuration options that you had set in a WSL 1 distro, such as automounting Windows drives, enabling or disabling interop, changing the directory where Windows drives will be mounted, etc. You may also leave feedback directly on GitHub.

You can expect to see more details about this experience soon as we get closer to the WSL 2 release. We currently have no plans to deprecate WSL 1.
