But all of your diagnostics seem more related to descriptor access,
which is a different layer than the ohci code. Both sound drivers
give you funkiness, and sound has unique descriptor handling, which
did change (more textually than behaviorally) in 2.5.45...
Thanks David,
Is anyone working on an update for the OSS audio driver? I'm going to
take a look, but it's all new to me. Is there another USB driver that
already was ported to the newer descriptor handling (or did you mean
that the sound layer changed descriptor handling? An example there
would help also.)
I recall seeing a patch go in to 2.5.49 to fix an altsetting issue.
See if that helps ... it'd affect both the OSS and ALSA usb-audio code.
Re what changed, look at <linux/usb.h> and notice how the descriptors
are now split out from the host-side "wrapper" data for them. That
was a fairly invasive change, and in some cases thing got converted
to use the descriptors when they should have used the wrappers.
