So having watched these threads over the past week, I have some comments: First, you have a very finicky device. The mode issue needs to be resolved. Depending upon the template (fedora/debian) and version (-xx) there is very likely an executable you can install via apt or dnf in a template to control it. Second, *USB-connected* *network* devices are often difficult get working in Qubes because of the use of sys-usb to "virtually" connect the device to your "network" VM using the "usbip" stack. The issues arise due to defects or unsupported functions in the linux usbip stack (not Qubes), which make things fail. In particular, I have found that a device that can reconfigure itself to appear to change type is likely not going to work with usbip. Therefore: my recommendation is to avoid utilizing usbip at all, which means avoiding the usb-attach/usb-detach features of Qubes entirely (that is, avoid managing this device using qvm-usb and/or the device widget). You can either make your current sys-usb into a provides-network VM (easier, but not the way I'd go...unless I already devices dependent on that config) or use the salt feature to uninstall the entire sys-usb feature (removing the sys-usb VM) and instead manually assign the entire usb controller to sys-net, utilizing qvm-pci in dom0 to attach the pcie device. That way, you're only dealing with issues in one VM which you can treat as a regular fedora or debian install. There are likely existing resources that can tell you how to manage the mode switch of that device with that version of fedora or debian. That's all I have. Brendan PS - the second approach, removing sys-usb altogether, assumes you don't have a USB-based keyboard or mouse (or other important peripherals) that you've set up to work through sys-usb. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
