this most likely means your device is not supported by the linux usbip
driver, so it will not work with qvm-usb forwarding between VMs.

you should still be able to use it in sys-usb, so you may have to use
sys-usb as your netvm while using that modem.

this problem applies to all USB devices that try to reset the USB device,
for example after loading firmware.

linux-5.5.6/drivers/net/wireless/ralink/rt2x00/rt2x00usb.c:
usb_reset_device(usb_dev);

Thanks! Yes, exactly this issue. Can I use passthrough mode if I will connect external 2.0 usb hub to my current notebook usb port and then passthrough from it?

/ or maybe it will be possible to attach second usb hub as pci device to other appvm?

if you have more than one pci-level usb-controller, you can (try to)
assign them to different VMs, sure.
but connecting some usb-to-usb hub and trying to assign that wont work.
