Hi,

I've tried to attach my Logitech, Inc. QuickCam Pro 4000 to a PS3 running Fedora 12.

I get this error in dmesg

pwc: Failed to set video mode QSIF@10 fps; return code = -110

Everything works well on a standard x86 laptop running Fedora 11.

Anybody has an idea why a different architecture could affect pwc?
I don't know, problems with little/big endian?

This is what I see in dmesg

I've recompiled pwc adding some extra logging and this is the output

The first error is

kernel: pwc: Failed to set LED on/off time; error -110 .    <<<<<<<<<<<<<< this is the first error

Does anybody know what -110 means?

Moreover, these 2 lines DON'T happen on a x86

kernel: pwc: probe() called [046D 08B2], if 1
kernel: pwc: probe() called [046D 08B2], if 2

any idea?

Thanks
