Bug#891036: The problem is related to the number of ports created in vhci_hcd.0

[Wojtek Zabolotny <W.Zabolotny@elka.pw.edu.pl>]

When I load the vhci-hcd driver in version 4.14, and then run "usbip --debug port", I get:

[...]
usbip: debug: names.c:428:[parse] line 18067 subclass fe:01 Device Firmware Update
usbip: debug: names.c:428:[parse] line 18068 subclass fe:02 IRDA Bridge

libusbip: debug: vhci_driver.c:264:[usbip_vhci_driver_open] available ports: 496
libusbip: error: port number exceeds 128
usbip: error: open vhci_driver
usbip: error: list imported devices

When i check /sys/devices/platform/vhci_hcd.0/nports it indeed contains 496 .
In other /sys/devices/platform/vhci_hcd.* directories there is no nports attribute at all.
