Hi,

I successfully tested the refreshed patch of Karsten using Fedora rawhide packages. Following are some informations on the test:

original kernel: 2.6.29-0.53.rc2.git1.fc11.x86_64 patched kernel: Linux 2.6.29-0.53.rc2.git1.ehcius122l.fc11.x86_64 #1 SMP Wed Jan 28 22:48:01 CET 2009 x86_64 x86_64 x86_64 GNU/Linux alsa: alsa-lib-1.0.19-1.fc11, alsa-plugins-usbstream-1.0.18 jack: jack-audio-connection-kit-0.116.1-3.fc11 qjackctl: qjackctl-0.3.3-1.fc10 audacious: audacious-1.5.1-5.fc11

after plugin the Tascam US-122L:

[root@pollux Test]# tail /var/log/messages Jan 29 08:05:53 pollux kernel: usb 2-6: new high speed USB device using ehci_hcd and address 4 Jan 29 08:05:53 pollux kernel: usb 2-6: config 1 interface 1 altsetting 1 bulk endpoint 0x83 has invalid maxpacket 9 Jan 29 08:05:53 pollux kernel: usb 2-6: New USB device found, idVendor=0644, idProduct=800e Jan 29 08:05:53 pollux kernel: usb 2-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Jan 29 08:05:53 pollux kernel: usb 2-6: Product: US-122L Jan 29 08:05:53 pollux kernel: usb 2-6: Manufacturer: TASCAM Jan 29 08:05:53 pollux kernel: usb 2-6: SerialNumber: no serial number Jan 29 08:05:53 pollux kernel: usb 2-6: configuration #1 chosen from 1 choice Jan 29 08:06:08 pollux kernel: ALSA sound/usb/usx2y/usb_stream.c:457: underrun, status=4294967278 Jan 29 08:06:08 pollux kernel: ALSA sound/usb/usx2y/usb_stream.c:457: underrun, status=4294967278

and jack messages were

Tested by .mp3 file playback using audacious (with plugin jack).

Additional notes: the previous version of the patch is routinely used by myself, at least some Fedora users using my packages at http://pagesperso-orange.fr/La-page-Web-of-Phil/Tascam_US-122L/Telechargemen... , and under Debian and Ubuntu (Federico Briata web site at http://wiki.briata.org/doku.php?id=testing_us122l_under_linux ) under 2.6.26 and 2.6.27 kernel.

Hope it will be soon integrated to 2.6.29 devel.

Regards

Phil.
