[Bug 22070] Re: Logitech Quickcam Messenger is not usable

[Lee Jones]

With regards to:

> [  287.134873] gspca: usb_submit_urb alt 1 err -28

ERR -28 =: #define      ENOSPC          28      /* No space left on
device */

USB returns -ENOSPC when its bandwidth has been used up.

This is an issue with the USB subsystem, rather than GSPCA.

Normally when -ENOSPC is returned, the receiving driver goes into low
bandwidth mode, however ST6422 doesn't have a low bandwidth mode. Here
lies our problem. I'll have to do some more investigation on it next
week. The real problem is Lucid is LTS, making it very hard to add any
workarounds or code which may cause regression. I'll have a word with
the maintainer and see if we can come up with something.
