I have a Dell TB16 dock with Ethernet over USB, based on a Realtek 8152 chip.
The device appears fine in sys-usb VM using r8152 driver and ehci/xhci. So it works fine with direct PCI access to the device. Connecting the usb device (via 'dom0$ qvm-usb attach...') to sys-net VM triggers loading of vhci. After some dmesg says "cannot enable. Maybe the usb cable is bad?" and the device does not work in sys-net VM. Blacklisting/disabling vhci-hcd in sys-net VM does not help (connecting fails immediately). Does qubes usb attaching require vhci? I upgraded dom0/vm kernels, BIOS -> no help. The dock worked fine on this computer using bare-metal Ubuntu with equal kernel version. I would like to avoid merging sys-usb and sys-net... Thanks for any hint. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
