Package: usbip
Version: 2.0+4.14.13-1
Severity: important

Dear Maintainer,

When I try to access the USB devices exported with usbip from another
machine,
even before I try to access the remote usbip server I gaet the strange
error:

# modprobe vhci-hcd
# usbip port
libusbip: error: port number exceeds 128
usbip: error: open vhci_driver
usbip: error: list imported devices

Of course I'm not able to attach any device.

# usbip attach -b 4-1 -r 192.168.0.82
libusbip: error: port number exceeds 128
usbip: error: open vhci_driver
usbip: error: query

Even though the device is visible for my machine:
# usbip list -r 192.168.0.82
Exportable USB devices
======================
 - 192.168.0.82
        4-1: C-Media Electronics, Inc. : Audio Adapter (0d8c:000c)
           : /sys/devices/platform/soc/1c1b400.usb/usb4/4-1
           : (Defined at Interface level) (00/00/00)
           :  0 - Audio / Control Device / unknown protocol (01/01/00)
           :  1 - Audio / Streaming / unknown protocol (01/02/00)

           :  3 - Human Interface Device / No Subclass / None (03/00/00)

I have attempted to attach the device to the virtual machine (Knoppix
8.1) running
under QEMU. Everything worked correctly. So obviously it is a problem
with the current
version of Debian/testing.
