adb repeatably crashes xhci

[JamesRichardson]

Using "adb" - the android debugger - causes a repeatable USB crash. Its usually about 5 minutes after starting the "adb" server process.

The result is that all USB devices become disconnected (mouse / keyboard etc)

It is possible to recover the USB system by logging in over network and running the following

```
for port in $(lspci | grep USB | cut -d' ' -f1); do
    echo -n "0000:${port}"| sudo tee /sys/bus/pci/drivers/xhci_hcd/unbind;
    sleep 5;
    echo -n "0000:${port}" | sudo tee /sys/bus/pci/drivers/xhci_hcd/bind;
    sleep 5;
done
```

The following messages are visible in dmesg

```

This happens repeatably, and only with adb.

I saw this was filed against android... I dont know what package it should be filed against, but surely this is a kernel or driver problem. User programs should not be able to crash a device, surely.
