USB Hub/Ethernet adapter not managed at startup

[virtualsaver]

Hi,

I am using Vbox on Win 10 HOST and Win 7 GUEST

Using an USB Hub/Ethernet adapter I have seen the following issue:

1 USB Hub/Ethernet adapter connected to the HOST (working fine)
2 starting Vbox & VM
3 no Ethernet adapter in VM (usb filter on)
4 unlug and replug Ethernet adapter present in VM and working fine (usb filter on)

To prove I have attached VM logs and also

1 usbhost_Pre.txt (before starting Vbox & VM)
2 usbhost_StartVM.txt (after starting Vbox & VM)
3 usbhost_PostUnplug.txt (after unplug and replug)

Thank you

Thanks for the usbhost outputs. Here's what I see regarding the USB Ethernet adapter:

Current State:      Captured

I don't know the significance of the UUIDs changing between runs of the 'list usbhosts' command, but the "Current State" only shows Captured after the unplug & replug. This is consistent with previous behavior of Virtualbox USB as stated in USB basics and troubleshooting: Some devices need to be physically unplugged/replugged to work right.

Hubs are not usable for filtering in Virtualbox, though the devices on the hub can be used. If your device works without un/replugging when connected directly to the host PC, but requires an un/replug when connected to the hub, then you might have hit a limitation of Virtualbox, USB, or both. You can post suitable evidence on the Bugtracker if you wish.

Hi ,

my device in an HUB (3 ports) with an Ethernet port. Total 4 ports.

I reported the issue because I guess the Vbox Usb drive doesn't work properly with this kind of "combo" device

Yes, works properly on the HOST.

About your sentence "Hubs are not usable for filtering in Virtualbox, though the devices on the hub can be used."
I can confirm it works fine, I normally use USB filter connected or not to the HUB

Thank you

Hubs are not usable for filtering in Virtualbox, though the devices on the hub can be used.

What this means is that a hub is invisible to Virtualbox (actually hubs aren't not invisible, but the developers, at the behest of the Oracle paying customers, made them invisible) for the purpose of making USB filters. So you can't attach several USB devices to a hub, then set a Virtualbox filter to the hub, and have any & all devices on that hub go into a guest just because they're attached to that hub. Would be cool if it were possible, but Virtualbox is not programmed for it.

Your Ethernet & hub device is probably a four port hub with a USB-Ethernet adapter hardwired to one of the hub ports. So the Ethernet part is the part that gets registered as a USB device and the hub is passed through invisibly. Add another device to that hub and that device will require its own USB filter.
