It sounds plausibly. But in this case i would expect error -28 (no space), rather then -110 (time out). Any way, currently only you can test if it's true. If you use debian you can probably use precompiled ubuntu kernels: http://kernel.ubuntu.com/~kernel-ppa/mainline/ plese test nest and older kernels. If still no results, then try other quirks: #define UVC_QUIRK_STATUS_INTERVAL 0x00000001 #define UVC_QUIRK_PROBE_MINMAX 0x00000002 #define UVC_QUIRK_PROBE_EXTRAFIELDS 0x00000004 #define UVC_QUIRK_BUILTIN_ISIGHT 0x00000008 #define UVC_QUIRK_STREAM_NO_FID 0x00000010 #define UVC_QUIRK_IGNORE_SELECTOR_UNIT 0x00000020 #define UVC_QUIRK_FIX_BANDWIDTH 0x00000080 #define UVC_QUIRK_PROBE_DEF 0x00000100 #define UVC_QUIRK_RESTRICT_FRAME_RATE 0x00000200 then if no results, test if device works at all with some alternate OS :) - -- Regards, Alexey -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk7huKkACgkQw8E0jNwoJm9kuwCgk17XJVEcdZRn3cpCOjRGp4B/ xgMAn1ymggANBE71tmLDLwBG1wi6Ckqi =oODy -----END PGP SIGNATURE----- _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
