Hi.
I must be really unlucky:
I have 2 webcams, tested on 3 differents freebsd (containing both
UHCI & OHCI devices).
The webcams are using pwc driver, from /usr/ports/multimedia/pwcbsd.
I have applied the patch to use one of them with "motion"; but
have every time the same error: "Too many ISOC errors, bailing out."
pwcbsd is a version 1.4.1, it's seem old enought to be "stable", so
I just can't figure out what's happening. Even pwcview don't work:
it's just light-on the cam a fraction of seconds, clear the screen
then give back the prompt.
Here are the specs of what I have tested:
home-made desktop
freebsd 6.2-STABLE/amd64
recompiled kernel
usb: ohci
hp nc4000,
FreeBSD 6.1-BETA4/i386
generic kernel
Usb: ohci
sony laptop (p800-quite-old)
freebsd 7.0 Beta/i386
generic kernel
usb: uhci
(except for those 2 laptops, I can install & test
any freebsd version and even give an ssh access on
a fixed ip...)
The webcams:
Apr 11 20:53:37 nc4000 kernel: pwc0: vendor 0x046d product 0x08b2, rev
1.10/0.00, addr 2
Apr 11 20:53:37 nc4000 kernel: pwc0: Logitech QuickCam Pro 4000 USB webcam
Apr 11 20:53:38 nc4000 kernel: pwc0: This camera is equipped with a Sony
CCD sensor + TDA8787 (32)
Apr 11 20:23:34 nc4000 kernel: pwc0: vendor 0x0471 product 0x0329, rev
1.10/0.03, addr 2
Apr 11 20:23:34 nc4000 kernel: pwc0: Philips SPC900NC USB webcam
Apr 11 20:23:35 nc4000 kernel: pwc0: This camera is equipped with a Sony
CCD sensor + TDA8787 (32)
Apr 11 20:23:41 nc4000 kernel: pwc0: Too many ISOC errors, bailing out.
(unfornutaly, I have bought the philips thinking the logitech
was the problem, but it's seems the both are in fact the same thing
with different plastics...)
T.I.A. PM.
