Summary

This patch introduces userspace-only USB passthrough using libusb. It
supports configuring passthrough via a (passthru.vid.pid) tuple.
Currently, only vendor and product ID-based selection is implemented;
selecting specific ugen devices (to differentiate between identical
devices) would require changes to libusb.

All USB transfer types—control, bulk, interrupt, and isochronous—are
supported. Hotplugging is also handled, allowing devices to be unplugged
when guest startup and replugged afterward without issue.

I have to second the *wow* given I have started this myself not knowing you are working on it.

I'll be happy to contribute the code for ugen selector as I have multiple v/d duplicates on laptops. doesn't need libusb changes, just a bit more parsing and looping (assuming my code fits in yours).
ugen matching isn't ideal either as you unplug/plug things and the bus.addr change and you have to update the config file... If you meant adding ugen checks on top of v/d then...

I think some of the fixes should be factored out upfront and commit separately.

I'll definitively test this by the end of the week with smart cards, some licensing dongle (very weird thing), and some wifi dongles.

usr.sbin/bhyve/usb_passthru.c
484	Can we name them by what they are? vid/pid or idVendor / idProduct?

Ah, I think you want to get whole device list and find the correct libusb device.

You are right, If we select the ugen manually, the hotplug is unable to work unless the device has serial number.

I would like to separate the patches but I think it is more convenient for people to test now.

usr.sbin/bhyve/usb_passthru.c
484	The reason why it is called param1 and 2 is that we may have different backend other than passthru in the future (thought I can’t image any circumstance we need that). So param1 and 2 is more generic.

Also, thanks for helping me test it!

I have tested on Windows and works fine. An interesting thing is that when I plug in a Linux Live CD. The UEFI shell recognize it and want me to install Linux:).

For some reason when passing through an SSD with a sata-to-usb3 adapter, it causes bhyve to crash when the Linux kernel is starting to boot.

However, regular usb3 mass storage works fine and is recognized.

With your latest changes, it does prevent bhyve from crashing. Appreciate it!

So, now it seems to create an additional 22 second stall at boot compared to without passing through the ssd with usb adapter.

When fully booted, it seems like it doesn't recognize it as if it weren't passthru'd.

Hello, could you please set the xhci_debug=1 and usb_passthru_debug=1 in bhyve and send me the report? The report maybe very long I think.

I'm still going through the code, but here's a few preliminary comments :)

Thanks for working on this!

usr.sbin/bhyve/pci_xhci.c
2038–2039	`dev->dev_ue` should always be set no?
2784
usr.sbin/bhyve/usb_emul.h
53	Could you elaborate on what this is in a comment? (nit: also missing tab)
usr.sbin/bhyve/usb_passthru.c
32	imo `is_in` or something would be clearer. But also, what value should a control endpoint have here, since it is bidirectional?
224	Should be after `done:` label
424	This isn't the only failure case for `libusb_init_context`, right? I fear this error might be too specific and cause confusion. Maybe you wanna use `libusb_error_name` here.
435–441	perhaps we should do some input validation here for param1/2
446	nit: `vid=%0lx pid=%0lx` would make things more obvious for people encountering this error message
458–462	You can use `UD_IS_USB2/3` here (this just checks the major so you're fine w.r.t. `>=`). Also, is it fine to set the USB version to 2 if bcdUSB is `0x0110` e.g.?
463	nit: I kinda feel like an explicit `configured` member per endpoint would be clearer instead of setting the type values to -1. But I don't feel strongly about this
494–495	You are turning the libusb error code into a USB error code in `usb_passthru_guest_attach_device` with `libusb_error_to_usb_error`, so guessing you meant to check `!= USB_ERR_NORMAL_COMPLETION`
806–807	Clearer if `type & 3` was `UE_GET_XFERTYPE`. Didn't find an equivalent macro for checking if type is in/out, but it would be nice to add one if doesn't exist

Quick question. How can I go about setting those options and generating the report using vm-bhyve? I already patched it using the diff from your github PR.

Hello, sorry it is from the code directly since it works like the normal DPRINTF. xhci_debug is in pci_xhci.c. usb_passthru_debug is in usb_passthru.c

Hello, could you please set the xhci_debug=1 and usb_passthru_debug=1 in bhyve and send me the report? The report maybe very long I think.

Quick question. How can I go about setting those options and generating the report using vm-bhyve? I already patched it using the diff from your github PR.

Hello, sorry it is from the code directly since it works like the normal DPRINTF. xhci_debug is in pci_xhci.c. usb_passthru_debug is in usb_passthru.c

Gotcha, thanks for clarifying: Here is the report (3911 lines): https://gist.github.com/kenrap/ecfc003562bd8717900a46de4903d7bf

Thanks @obiwac!

usr.sbin/bhyve/usb_passthru.c
32	Since it is for data only (bulk, intr, and isoc). Therefore, we don't have to care about control endpoint in here. For control xfer (endpoint 1), we will call ue_request instead of ue_data. I think a control endpoint other than ep number 1 is undefined behavior.
458–462	The xhci itself have two controller. One is for usb 1.0, 2.0 devices, another is for usb 3 devices. Setting the value to here is just for helping us know which controller should we use. If you open in a Windows Guest. You will see there is a xHCI and a eHCI even if we only have a xHCI instance. So setting the value 2 is fine here. Also, the bcdUSB returns from the libusb is just a uint16_t instead of a uint8_t[2], so I think UD_IS_USB2 will not work?

Sorry, I know that it is a little bit annoying. But since I don't have such device. Could you please try again?

No worries, I want to make sure this gets done right. I'll be your beta tester for this. 👍

I'm rebuilding my src tree now.

No difference. The report: https://gist.github.com/kenrap/9a1c406d097aa12c7a7b7ebe106cb681

So, there is good news and bad news.

Good news is, the boot time went down significantly to 6 seconds.

The bad news, the device is still not detected by the guest OS.

Hello: Does your device work on FreeBSD host? I saw a transfer is cancelled so the problem maybe on the libusb side or kernel stack.

Sorry for the late reply. Yes, I'm able to mount the device on my FreeBSD host.

Hello, I think I need to at least get a usb 3 hub to test this feature since I haven’t had any super speed device. I will take a look at the candidates hub. However, I am occupied by other stuff recently. Maybe you won’t get any feedback very soon (Maybe a months afterI promise that I will be back ASAP since I would like to finish this feature. Sorry for your inconvenience on helping me test this!

Appreciate the heads up. I'll be on standby.

Hi, I've tested this with a licensing dongle and a smart card reader on an external USB HUB with Windows 11. Licensing worked, smart card was detected correctly. I am still wondering if param1/2 in the config are the best thing but they work, so be it. Many thanks to you and the FreeBSD Foundation! I'll keep trying and using it for other bits as well the next days on other machines. I just need to disable the debugging as my remote window kept scrolling (have the tablet on for vnc as well in this case) like I was on a 9600 connection downloading Netscape ;-)

It's gotten silent here. May I ask what the plan is? Is there a chance to get this work into 16?

Hello. I received the notice of conscription for 4 month obligatory military service in my country in late Octorber which have started from November. I will continue to work on this after my service.
