Hi there,
I have several other devices captured successfully using usb filters.
However, trying to capture a TI EV2400 (usb2i2c adapter) makes it disappear from the list (no matter if I try on the fly or by filter).
So the device won't show anymore in the host or the list, and "No attached devices" is shown when hovering over the bottom right USB icon.
If replugging the device with the filter on, the same thing happens.
If the filter is off, replugging the device makes it appear in the host, but any attempt to capture on the fly or reenabling the filter makes it disappear.

I have added the related information as an attachment, as the system does not let me post "urls" (!?).

The VBox.log is also attached.

How about the output of:

```
VBoxManage list usbhost
```

before and after you select the device? You already included the before... Also, can you unplug everything not-related and simplify your setup? And plug the device directly, not through a hub?

Hi Socratis,

I have now unplugged as much as I can. The remaining iare things connected to my dock where I have my keyboard and mouse kvm, so not rasy to unplug without stopping completely everything I am doing...

This is what linux shows when the VM is stopped and the device is plugged for reference (offending device connected to Bus01 root hub, port #2, not through any other hub)
N.B. the port #2 is a type-C connector using an adapter from type-c socket to type-a socket.

Dock? What dock? When did this come into the equation? I would like you to try with the simplest case, and that should not involve a dock. It might be the dock-connection that's at fault. There are plenty of tickets about docking laptops and all sorts of things going crazy.

Hmm... that could also be problematic. Is it a USB 3.1 port? Again, searching for "USB-C", shows plenty of hits...

Calm down... I am not using any dock in between, but my keyboard and mouse go to a dock on a different port, so I cannot remove that easily. It al just mean that you see a few other devices in other root ports. The "dock" are just two usb hubs in a completely different root port.

You can see that the device is connected to the 480Mb of the usb 3.1 port, i.e. Bus 01 Port 2 at the top of my previous answer, where I show you the result of lsusb -vvt.

I'll try something simpler, just the laptop, for your own sanity, tomorrow early morning... but I am sure that won't make any difference. It is just a usb 2.0 hub with the usual old ps2 keyboard and mouse, ear/mic jacks and a serial and parallel port.

A bit late due to my holidays, but here it is:

Hi, I have to deal with same device as you. Other USB devices work fine in Virtualbox (eg ST-link V2). I have found out, that every device is reset when being captured. Using simple utility from question on StackOverflow (sorry, registered tody, can't post links) I tried to reset it manually and same error happened.

...and device remains dead until reconnected. Exactly same behavior when Virtualbox captures this device.
Thus, it is not Virtualboxes' blame. It must be kernel bug or device USB implementation sucks and I put my bet on device.

Thank you 'xorly' for the analysis!

I don't think it's a VirtualBox issue too. There are too many links in the chain that can go wrong, in this case I tend to agree with you that it's a device problem, not a Host or a VirtualBox problem...

EV2400 behaves like regular USB HID device. I'd guess, other HID devices works in VBox.

Here, I am trying to convince TI, that their USB implementation in EV2400 is broken.

Basically, EV2400 can't handle more than one initial USB reset request during device enumeration. However, it is necessary to reset USB device to be released by host OS and captured by Vbox for guest OS. (Beutiful piece of.... HW for €200, right?)

There is dirty workaround though! (GNU/Linux Host, Windows guest)

boot your virtual machine without USB filter
open terminal on host and execute (live kernel log)
Code: Select all
```
dmesg -w
```
do the "on-the-fly" device capture, now you'll start seeing USB errors in log
press and release reset button on EV2400 (there is small hole in plastic case)
errors should stop and device will be be available to guest OS

Sometimes, it is necessary to press reset button more than once. If capture fails, try again. As I said, it's dirty...
