webcams : Too many ISOC errors, bailing out.

[Me]

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.

uplcom seems to have solved the problem.

FreeBSD 6.2 and USB Serial Port

[Thomas D. Dean]

I attempted to use a Prolific Technology USB-Serial Controller on FreeBSD 6.2.

I have ucom and uftdi loaded.

I am using a Logitech Receiver for keyboard and mouse on usb0 addr1, port2.

I connect the USB-Serial Controller to usb1 addr1 port1.  usbdevs shows it.

When I connect the device, I see the console message and ugen1,ugen1.[1-3] in 
/dev.  However, none of cuaUx or ttyUx are created.

What am I doing wrong?
