This file contains some additional information for the Philips webcams.
E-mail: webcam@smcc.demon.nl Last updated: 2001-09-24
The main webpage for the Philips driver is http://www.smcc.demon.nl/webcam/.
It contains a lot of extra information, a FAQ, and the binary plugin
'PWCX'. This plugin contains decompression routines that allow you to
use higher image sizes and framerates; in addition the webcam uses less
bandwidth on the USB bus (handy if you want to run more than 1 camera
simultaneously). These routines fall under an NDA, and may therefor not be
distributed as source; however, its use is completely optional.

* usb_reset_devce - perform a USB port reset to reinitialize a device

*
* WARNING - don't reset any device unless drivers for all of its
* interfaces are expecting that reset! Maybe some driver->reset()
* method should eventually help ensure sufficient cooperation.
*
* This is the same as usb_reset_device() except that the caller
* already holds dev->serialize. For example, it's safe to use
* Do a port reset, reassign the device's address, and establish its
* former operating configuration. If the reset fails, or the device's
* descriptors change from their values before the reset, or the original
* configuration and altsettings cannot be restored, a flag will be set
* telling khubd to pretend the device has been disconnected and then
* re-connected. All drivers will be unbound, and the device will be
* re-enumerated and probed all over again.
*
* Returns 0 if the reset succeeded, -ENODEV if the device has been
* flagged for logical disconnection, or some other negative error code
* if the reset wasn't even attempted.
*
* The caller must own the device lock. For example, it's safe to use
* this from a driver probe() routine after downloading new firmware.
