usb_get_device_descriptor when building for 2.6.2-rc3

usb_get_device_descriptor when building for 2.6.2-rc3

[Frank Barknecht]

Hallo,

I'm trying to build ALSA-CVS for 2.6.2-rc3, because that kernel has
support for the emi62m firmware. Now I get unresolved symbols in
snd-usb-audio: 

request_module: failed /sbin/modprobe -- snd-card-1. error = 256
snd_usb_audio: Unknown symbol usb_get_device_descriptor

Can anyone help?

ciao

do you enable the modle version?
then you'll need to rebuild alsa-driver, too.

well, it turned out that the USB in 2.6.2-rc3 changed its API... :-<
we'll need a hack again.

No, I didn't enable mod versions. Should I?

Yes, I did that. I ran configure again and "make dep; make; make
install-modules"

Previously there was Kernel 2.6.1 installed, so the modules were
installed into another, new directory anyways.

Oh, and the ice1712 driver, I also built, is working.

Urgh. ;)

Well, but I've found out another thing: There was a compile warning in 
usbaudio.c at function snd_usb_extigy_boot_quirk() about "implicit
definition of usb_get_device_descriptor" or similar.

Temporarily I commented out lines 2632 and 2634, after that
snd-usb-audio loaded without the error.

I will now try to plug in a USB device. But first I send this mail, in
case anything goes badly wrong. :)

I'm still alive! 

Now it works with e.g. the Maya Audiotrak 5 I plugged in, which was
well behaving in the past days. 

Still no luck with the emi62 though. I'll post the new error messages
to the other thread.
