           Summary: ehci-hcd stops responding when USB 1.1 storage device
                    inserted
    Kernel Version: 2.6.11 (vanilla)
            Status: NEW
          Severity: high
             Owner: greg at kroah.com
         Submitter: vitko at post.cz


Distribution: Debian/unstable
Hardware Environment: Pentium III (Intel 440BX/ZX/DX)
Software Environment: kernel 2.6.11 (vanilla)

Problem Description:

USB 2.0 port freezes when specific USB 1.1 flash drive is inserted. No kernel
messages since then, even when plugging/unplugging other devices.

Steps to reproduce:

rmmod ehci_hcd for a clean start, dmesg output follows:

   ehci_hcd 0000:00:10.2: remove, state 1
   ehci_hcd 0000:00:10.2: roothub graceful disconnect

   ehci_hcd 0000:00:10.2: USB bus 2 deregistered

Now modprobe ehci-hcd

Now I'm going to plug in Swissbit Blacksilver 32 MB, device details from
udevinfo when used with uhci-hcd:

   BUS="usb"
   ID="1-2"
   DRIVER="usb"
   SYSFS{bConfigurationValue}="1"
   SYSFS{bDeviceClass}="00"
   SYSFS{bDeviceProtocol}="00"
   SYSFS{bDeviceSubClass}="00"
   SYSFS{bMaxPower}="100mA"
   SYSFS{bNumConfigurations}="1"
   SYSFS{bNumInterfaces}=" 1"
   SYSFS{bcdDevice}="0110"
   SYSFS{bmAttributes}="80"
   SYSFS{detach_state}="0"
   SYSFS{devnum}="4"
   SYSFS{idProduct}="6828"
   SYSFS{idVendor}="1370"
   SYSFS{manufacturer}="SWISSBIT"
   SYSFS{maxchild}="0"
   SYSFS{product}="Black Silver    "
   SYSFS{serial}="403501400A23F962"
   SYSFS{speed}="12"
   SYSFS{version}=" 1.10"

and dmesg output after plugging the device in

   hub 2-0:1.0: state 5 ports 5 chg 0000 evt 0010
   ehci_hcd 0000:00:10.2: GetStatus port 4 status 001803 POWER sig=j  CSC CONNECT
   hub 2-0:1.0: port 4, status 0501, change 0001, 480 Mb/s
   hub 2-0:1.0: debounce: port 4: total 100ms stable 100ms status 0x501
   ehci_hcd 0000:00:10.2: port 4 full speed --> companion
   ehci_hcd 0000:00:10.2: GetStatus port 4 status 003801 POWER OWNER sig=j  CONNECT

now port is frozen, no other dmesg info when i try to plug/unplug anything.

It is still possible to rmmod ehci-hcd and reload, ehci-hcd then plays fine with
any other storage device, also can be repeatedly frozen using aforementioned
Swissbit Blacksilver 32 MB flash disk.
