Hi!
A few days ago in the alsa users mailing list, Clemens pointed to a
recent patch for the EHCI driver [1] [2] for solving the following
problem:
The current TT scheduling doesn't allow to play and then record on a
full-speed device connected to a high speed hub.
I've had the same problem.
From what I've been able to gather from the LKML is that this occurred
before the 3.2 staging merge.
I'm looking forward to trying it out UA25EX / Asus N53SV (7 series) -
would have done so already but my equipment is still in transit. Will
let you know in a week or so when my container gets here.
regards,
Brendan
This patch has made it to the 3.3 kernel in Fedora and for some users
this has fixed the error "cannot submit datapipe for urb 0, error -28:
not enough bandwidth" on USB fullspeed devices like the UA25-EX.
regards,
Brendan
