Hi,
this adds some scanners reported to be crashed by autosuspend to

Hi All
This is another iteration of the authorization patches. Below I
include the same design/rationale for the implementation. Since try
#2, this is what has changed:
- ported over to 2.6.22
- added docs in Documentation/usb
- Moved from using device class to the device directory
- add usb_dev_
If called and the device is not authorized to be used, then we don't
allow reading the configurations.

If called and the device is not authorized to be used, then we won't

This just modifies 'struct usb_device' to contain the 'authorized'
bit. It also adds a 'wusb' bit. This is needed because nonauthorized

These USB API functions will do the full authorization/deauthorization

Effectively this means that we have to clean all the configuration

Just tried 2.6.21-rc1 and I get the same problem. Are there snap shots
before this?
Attached is a dmesg dump from a 2.6.20.11 kernel on the same hardware config.

I found the first regresson in the rewritten ("all dynamic" and "no races")
driver. If application uses O_NONBLOCK, I return -EAGAIN despite the URB
being submitted successfuly. This causes the application to resubmit the
same data erroneously.
The fix is to pretend that the transfer has succeeded
