7 | NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx | |
8 | driver and thus may have bugs that are not present in the original version. | |
9 | Please send bug reports and support requests to <luc@saillard.org>. | |
10 | The decompression routines have been implemented by reverse-engineering the | |
11 | Nemosoft binary pwcx module. Caveat emptor. | |

30 | This code forms the interface between the USB layers and the Philips |
31 | specific stuff. Some adanved stuff of the driver falls under an | |
32 | NDA, signed between me and Philips B.V., Eindhoven, the Netherlands, and | |
d56410e0 | 33 | is thus not distributed in source form. The binary pwcx.o module |
1da177e4 | 34 | contains the code that falls under the NDA. |

36 | In case you're wondering: 'pwc' stands for "Philips WebCam", but | |
1da177e4 LT |
37 | I really didn't want to type 'philips_web_cam' every time (I'm lazy as |
38 | any Linux kernel hacker, but I don't like uncomprehensible abbreviations | |
39 | without explanation). | |

41 | Oh yes, convention: to disctinguish between all the various pointers to |
42 | device-structures, I use these names for the pointer variables: | |
43 | udev: struct usb_device * | |
9a7b2d1f | 44 | vdev: struct video_device (member of pwc_dev) |
1da177e4 LT |
45 | pdev: struct pwc_devive * |
