#77505 — Bug#1025735: linux-image-6.0.0-5-amd64: Logitech camera only uses USB 1.1 (Full speed), not enough bandwidth

Package: src:linux
Version: 6.0.10-2
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   My Logitech Inc. QuickCam Communicate STX USB Webcam 046d:08d7 can't
   use USB 2.0, although the manufacturer says it supports it. It is not
   a hardware problem, I have the same camera 2 times and I tried
   different port and computers. It even happens on different machines.
   The port definitely supports USB 2.0, I have verified that with
   another USB device.

   That causes that the bandwidth is not enough for the higher
   resolutions. This results in a faulty image in certain applications
   like Firefox or Microsoft Edge.

   Message in dmesg
   [  193.679885] gspca_main: gspca_zc3xx-2.14.0 probing 046d:08d7

[  668.959675] gspca_zc3xx 1-1.5:1.0: alt 6 - bandwidth not wide enough, trying again
##After I connected the camera
[ 3752.435797] usb 1-1.5: new full-speed USB device number 7 using ehci-pci

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     Ineffective: Use another USB port, use another camera (same model) on the same machine

   * What was the outcome of this action?
     Same situation, camera only uses USB 1.1. Picture disturbed, camera not usable with high resolution.
   * What outcome did you expect instead?
     The camera should use USB 2.0 to provide enough bandwidth.

Has it worked properly before with an older kernel? If so, which?

No, it is a general problem.

#77540 — Bug#1025735: Bug 1025735

From the logs, it seems that you're using this camera on an old
hardware. I remember lots of troubles related to old USB 2.0
bridges.

See, USB 2.0 spec supports two types of velocity:

	- full-speed (the same as USB 1.1 speeds;
	- high-speed (the one which comes with USB 2.0)

In thesis, USB 2.0 is meant to allow up to 480MBps, but this is not
what happens in practice, specially for cameras. Cameras typically
use ISOC endpoints, with works by allocating a certain number of
frames or microframes. This is limited, according to the spec, to:

	- max of 90% of frames can be allocated on full speed
	  (e. g. being used either ISOC or interrupt endpoints).
	- max of 80% for for microframe periodic transfers
	  (high speed).

When there a mix of USB 1.1 and USB2.0 at the same bus, those numbers may
drop radically, as USB 1.1 devices won't work at high-speed. So, the USB
core may fail to be able to allocate the required number of frames or
microframes as required by the device to work on its full resolution.

I bet this is the case, from your lsusb:

	** USB devices:
	Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
	Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
	Bus 001 Device 005: ID 047f:4315 Plantronics, Inc. Poly Blackwire 8225 Series
	Bus 001 Device 004: ID 046d:08d7 Logitech, Inc. QuickCam Communicate STX
	Bus 001 Device 003: ID 13ba:0018 PCPlay Barcode PCP-BCG4209
	Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
	Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


See at bus 1, where the camera is connected, you also have a barcode
reader, which is very likely an USB 1.1 device (as most input devices
are).

Ah, there are also some USB 2.0 bridges that are internally 
connected to USB 1.1, and sometimes end having similar troubles.

Worth mentioning that "USB 2.0 compatible" announcements on hardware
doesn't necessarily means that they support high-speed, as full-speed
is also part of USB 2.0 specs.

In any case, this has nothing to do with the V4L driver, but, instead,
to how the USB brigde and USB core/driver detects each device. You can
have a better view about how the USB devices are seen with `lsub -t`:

	$ sudo lsusb -t

On the above example, the camera is at Bus 1 port 6, which is set to use
high-speed ("480M"). Other ports at the same bus have devices at 
high-speed ("12M"). Yet, this specific USB bridge handles each port
in separate, so the camera (using uvcvideo) can allocate all ISOC microframes
it needs.

Older USB bridges (found on machines similar to the one pointed on your
BZ) don't allow that: if one device at the bus is at full-speed, all
devices at the same bus have their speed reduced to full-speed, as
otherwise the full-speed devices wouldn't work.

Switching the camera connector to different USB ports may help. 

When there is the need of connecting input devices (they all are usually
full-speed only), you can also try using modern USB hubs, as some are
capable of isolating full-speed devices on a separate internal bus, talking
with the PC port in high-speed.

I actually meant to say:

full-speed ("12M").
