Re: [linux-audio-user] Hardware recommendations

Still remains a bug, or perhaps a different bug. As per an email exchange with clemens, I had got this patch: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg35743.… I fetched the then-current linus 2.6.12 git kernel sha1: 59a49e38711a146dc0bef4837c825b5422335460 Patched in alsa 1.0.9b - which went in fairly cleanly, btw - patched in the above patch, compiled for the x86_64, and with great hope, plugged in the ua-1000 again. Nope, same crash on unplug, and it doesn't appear to recognise the device properly... from /var/llog/messages Jun 24 18:07:34 localhost login(pam_unix)[4203]: session opened for user root by LOGIN(uid=0) Jun 24 18:07:34 localhost -- root[4203]: ROOT LOGIN ON tty1 Jun 24 18:07:46 localhost kernel: usb 1-4: new high speed USB device using ehci_hcd and address 3 * nothing else Now, the dump of the panic on removal of the ua-1000 I haven't got - it's a long kernel panic and this laptop lacks serial port to send it out of. I will bring the ua-1000 into work and plug it into a machine that is externally rebootable as well as visible on the net, also running 2.6.12 released - but at the moment I plan to just return the ua-1000 monday afternoon based on the hum problem. On the other hand, getting devices to work is fun, so I've put a lsusb at the end of this message... Ha! I wonder how good edirol has been about releasing detailed information on their devices... I'm emailing them.... As it was, after upgrading to the 2.6.12+alsa+patch git kernel I discovered that my original 2 channel usb midi device wasn't working anymore, either, though it was properly recognised Jun 24 18:42:08 localhost kernel: midi: probe of 2-1:1.0 failed with error -5 Jun 24 18:42:08 localhost kernel: midi: probe of 2-1:1.1 failed with error -5 Jun 24 18:42:08 localhost kernel: usbmidi: found [ Roland UM-2 ] (0x0582:0x0005), attached: Jun 24 18:42:08 localhost kernel: usbmidi: /dev/midi00: in (ep:81 cid: 0 bufsiz:64) out (ep:01 cid: 0 bufsiz:64) Jun 24 18:42:08 localhost kernel: usbmidi: /dev/midi01: in (ep:81 cid: 1 bufsiz:64) out (ep:01 cid: 1 bufsiz:64) Jun 24 18:42:45 localhost kernel: Machine check events logged Jun 24 18:43:03 localhost kernel: scheduling while atomic: rosegardenseque/0x00000001/5734 Jun 24 18:43:03 localhost kernel: Jun 24 18:43:03 localhost kernel: Call Trace:<ffffffff803c1bf2>{thread_return+494} <ffffffff803c14aa>{schedule+122} Jun 24 18:43:03 localhost kernel: <ffffffff8030973f>{hcd_unlink_urb+1023} <ffffffff8030bb07>{usb_kill_urb+519} Jun 24 18:43:03 localhost kernel: <ffffffff8015de10>{autoremove_wake_function+0} <ffffffff80142ccf>{current_fs_time+79} Jun 24 18:43:03 localhost kernel: <ffffffff8015de10>{autoremove_wake_function+0} <ffffffff88198d9a>{:usb_midi:usb_midi_release+378} Jun 24 18:43:03 localhost kernel: <ffffffff801a2106>{__fput+118} <ffffffff801a037e>{filp_close+110} Jun 24 18:43:03 localhost kernel: <ffffffff801a053b>{sys_close+411} <ffffffff8010f446>{system_call+126} Jun 24 18:43:03 localhost kernel: or Jun 24 18:44:57 localhost kernel: scheduling while atomic: rosegardenseque/0x00000001/5740 Jun 24 18:44:57 localhost kernel: Jun 24 18:44:57 localhost kernel: Call Trace:<ffffffff803c1bf2>{thread_return+494} <ffffffff803c14aa>{schedule+122} Jun 24 18:44:57 localhost kernel: <ffffffff8030973f>{hcd_unlink_urb+1023} <ffffffff8030bb07>{usb_kill_urb+519} Jun 24 18:44:57 localhost kernel: <ffffffff8015de10>{autoremove_wake_function+0} <ffffffff80142ccf>{current_fs_time+79} Jun 24 18:44:57 localhost kernel: <ffffffff8015de10>{autoremove_wake_function+0} <ffffffff88198d9a>{:usb_midi:usb_midi_release+378} Jun 24 18:44:57 localhost kernel: <ffffffff801a2106>{__fput+118} <ffffffff801a037e>{filp_close+110} Jun 24 18:44:57 localhost kernel: <ffffffff801a053b>{sys_close+411} <ffffffff8010f446>{system_call+126} Jun 24 18:44:57 localhost kernel: Not sure how to get it in 1.1 mode, but here's lsusb -v attached...
