I've got this kernel (sound.git) booting now, but I find that USB
audio isn't working
before I touch it.
When I connect my (known working) UA-25, this happens:
[ 248.815369] usb 1-1.6: new full-speed USB device number 6 using ehci_hcd
[ 248.913064] usb 1-1.6: New USB device found, idVendor=0582, idProduct=0074
[ 248.913068] usb 1-1.6: New USB device strings: Mfr=1, Product=2,
SerialNumber=0
[ 248.913071] usb 1-1.6: Product: EDIROL UA-25
[ 248.913074] usb 1-1.6: Manufacturer: Roland
mtp-probe: checking bus 1, device 6:
"/sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.6"
mtp-probe: bus: 1, device: 6 was not an MTP device
[ 249.073737] cannot submit urb 0, error -28: not enough bandwidth
Any subsequent attempts to send audio to it result in a single "urb 0
error -28" message
I googled this a bit, and saw that there had been a problem looking like
this with USB full speed devices on ehci controllers, which does apply here.
Do you think that's what's biting me?
Cheers,
- Pete.
