Subject: USBIP is claiming all my USB devices - Commit 7a2f2974f265 is
 broken

All,

I was testing Linux 5.9-rc7 today when I realized that none of my USB devices
were responding anymore. For instance, my mouse does not respond and its usual
red LED is not on.

Reverting git commit 7a2f2974f265 solved the problem for me.

I have USBIP enabled in my kernel config. Alternatively, removing the following
CONFIG variables also resolved the problem for me:

-CONFIG_USBIP_CORE=y
-CONFIG_USBIP_HOST=y
-CONFIG_USBIP_VHCI_HCD=y
-CONFIG_USBIP_VHCI_HC_PORTS=8
-CONFIG_USBIP_VHCI_NR_HCS=1

I do not have any userland usbip daemons running on this PC.

I attached before-and-after versions of my "dmesg", "lsusb", and "lsusb -t"
outputs to demonstrate the problem. Versions marked .1 are with commit
7a2f2974f265 reverted. Versions marked .2 are without any changes to usbip.

# grep usbip dmesg.1
dmesg.1:usbcore: registered new device driver usbip-host

# grep usbip dmesg.2
dmesg.2:usbcore: registered new device driver usbip-host
dmesg.2:usbip-host 1-8: 1-8 is not in match_busid table... skip!
dmesg.2:usbip-host 1-13: 1-13 is not in match_busid table... skip!

>From lsusb_t.1:

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/16p, 480M
     |__ Port 8: Dev 2, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
     |__ Port 13: Dev 3, If 1, Class=Wireless, Driver=btusb, 12M
     |__ Port 13: Dev 3, If 0, Class=Wireless, Driver=btusb, 12M

>From lsusb_t.2:

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/16p, 480M

(no devices are listed when they should be)

I also attached my .config for review.

Thanks,
  -Byron
