>Description:
Hi,

(Not sure if it is USB or PwcBSD related)

I've just installed the new USB Stack and recompiled PwcBSD. My webcam (Philips SPC900NC) does not work anymore, here are the logs shown in /var/log/messages :

When I plug the webcam :

Oct  8 18:41:45 home kernel: usbd_fill_iface_data: invalid wMaxPacketSize, addr=125!
Oct  8 18:41:45 home kernel: pwc0: Philips product 0x0329, rev 1.10/0.03, addr 125
Oct  8 18:41:45 home kernel: pwc0: Philips SPC900NC USB webcam
Oct  8 18:41:46 home kernel: pwc0: This camera is equipped with a Sony CCD sensor + TDA8787 (32)

When I start pwcview, a small green screen appears and then disappears. Here are the logs :

Oct  8 18:51:54 home kernel: pwc decode_size = 3.
Oct  8 18:51:54 home kernel: pwc Using alternate setting 2.
Oct  8 18:51:54 home kernel: pwc frame_size=57600, vframes=5, vsize=3, vsnapshot=0, vbandlength=960
Oct  8 18:51:54 home kernel: usbd_transfer_done: short transfer actlen(0) < len(7680)
Oct  8 18:51:55 home last message repeated 20 times
Oct  8 18:51:55 home kernel: pwc0: Too many ISOC errors, bailing out.

Feel free to ask for any further details...
>How-To-Repeat:
Install the new stack from : http://www.turbocat.net/~hselasky/usb4bsd and update pwcBSD from /usr/ports/multimedia/pwcbsd.
>Fix:
No fix known.
