The problem is where I get that struct dev_state *owner parameter from. The closest to this I found to be the filelist member in struct usb_device. So I got the owner as: owner = list_entry(udev->filelist.next, struct dev_state, list); This works but that list is supposed to be the list of open files for that device. No files are opened in this case. Should I initialize a struct dev_state variable similary to usbdev_open()? Unrelated to this, USB/IP still has a problem when the device is no longer shared. In this case, the device should be rebound to the old drivers and be used normally. While resetting the configuration triggers a new binding process for interface drivers, on the core level, where usbip-host driver is, the device remains unbound. One hack-ish way to solve this would be to manually rebind the device to the old driver. Is there any better way to trigger a new driver binding at core level?
