In sound/usb/card.c and sound/usb/misc/ua101.c there are no spaces between the vendor and the device names, use this style in the other drivers too. This also helps keeping consistency when new drivers copies from the ones already in the mainline tree.

Version 0.8.7.2:
|
|
Call snd_card_free() instead of snd_card_free_in_thread() to prevent oops with dead keyboard symptom.
|
|
Tested ok with kernel 2.6.12-rc2.
|
|
|
|
2004-12-14 Karsten Wiese
|
|
Version 0.8.7.1:
|
|
snd_pcm_open for rawusb pcm-devices now returns -EBUSY if called without rawusb's hwdep device being open.
|
|
|
|
2004-12-02 Karsten Wiese
|
|
Version 0.8.7:
|
|
Use macro usb_maxpacket() for portability.
|
|
|
|
2004-10-26 Karsten Wiese
|
|
Version 0.8.6:
|
|
wake_up() process waiting in usX2Y_urbs_start() on error.
|
|
|
|
2004-10-21 Karsten Wiese
|
|
Version 0.8.5:
|
|
nrpacks is runtime or compiletime configurable now with tested values from 1 to 4.
|
|
|
|
2004-10-03 Karsten Wiese
|
|
Version 0.8.2:
|
|
Avoid any possible racing while in prepare callback.
|
|
|
|
2004-09-30 Karsten Wiese
|
|
Version 0.8.0:
|
|
Simplified things and made ohci work again.
|
|
|
|
2004-09-20 Karsten Wiese
|
|
Version 0.7.3:
|
|
Use usb_kill_urb() instead of deprecated (kernel 2.6.9) usb_unlink_urb().
|
|
|
|
2004-07-13 Karsten Wiese
|
|
Version 0.7.1:
|
|
Don't sleep in START/STOP callbacks anymore.
|
|
us428 channels C/D not handled just for this version, sorry.
|
|
|
|
2004-06-21 Karsten Wiese
|
|
Version 0.6.4:
|
|
Temporarely suspend midi input
|
|
to sanely call usb_set_interface() when setting format.
|
|
|
|
2004-06-12 Karsten Wiese
|
|
Version 0.6.3:
|
|
Made it thus the following rule is enforced:
|
|
"All pcm substreams of one usX2Y have to operate at the same rate & format."
|
|
|
|
2004-04-06 Karsten Wiese
|
|
Version 0.6.0:
|
|
Runs on 2.6.5 kernel without any "--with-debug=" things.
|
|
us224 reported running.
|
|
|
|
2004-01-14 Karsten Wiese
|
|
Version 0.5.1:
|
|
Runs with 2.6.1 kernel.
|
|
|
|
2003-12-30 Karsten Wiese
|
|
Version 0.4.1:
|
|
Fix 24Bit 4Channel capturing for the us428.
|
|
|
|
2003-11-27 Karsten Wiese, Martin Langer
|
|
Version 0.4:
|
|
us122 support.
|
|
us224 could be tested by uncommenting the sections containing USB_ID_US224
|
|
|
|
2003-11-03 Karsten Wiese
|
|
Version 0.3:
|
|
24Bit support.
|
|
"arecord -D hw:1 -c 2 -r 48000 -M -f S24_3LE|aplay -D hw:1 -c 2 -r 48000 -M -f S24_3LE" works.
|
|
|
|
2003-08-22 Karsten Wiese
|
|
Version 0.0.8:
|
|
Removed EZUSB Firmware. First Stage Firmwaredownload is now done by tascam-firmware downloader.
|
|
See:
|
|
http://usb-midi-fw.sourceforge.net/tascam-firmware.tar.gz
|
|
|
|
2003-06-18 Karsten Wiese
|
|
Version 0.0.5:
|
|
changed to compile with kernel 2.4.21 and alsa 0.9.4
|
|
|
|
2002-10-16 Karsten Wiese
|
|
Version 0.0.4:
|
|
compiles again with alsa-current.
|
|
USB_ISO_ASAP not used anymore (most of the time), instead
|
|
urb->start_frame is calculated here now, some calls inside usb-driver don't need to happen anymore.
|
|
|
|
To get the best out of this:
|
|
Disable APM-support in the kernel as APM-BIOS calls (once each second) hard disable interrupt for many precious milliseconds.
|
|
This helped me much on my slowish PII 400 & PIII 500.
|
|
ACPI yet untested but might cause the same bad behaviour.
|
|
Use a kernel with lowlatency and preemptiv patches applied.
|
|
To autoload snd-usb-midi append a line
|
|
post-install snd-usb-us428 modprobe snd-usb-midi
|
|
to /etc/modules.conf.
|
|
|
|
known problems:
|
|
sliders, knobs, lights not yet handled except MASTER Volume slider.
|
|
"pcm -c 2" doesn't work. "pcm -c 2 -m direct_interleaved" does.
|
|
KDE3: "Enable full duplex operation" deadlocks.
|
|
|
|
|
|
2002-08-31 Karsten Wiese
|
|
Version 0.0.3: audio also simplex;
|
|
simplifying: iso urbs only 1 packet, melted structs.
|
|
ASYNC_UNLINK not used anymore: no more crashes so far.....
|
|
for alsa 0.9 rc3.
|
|
|
|
2002-08-09 Karsten Wiese
|
|
Version 0.0.2: midi works with snd-usb-midi, audio (only fullduplex now) with i.e. bristol.
|
|
The firmware has been sniffed from win2k us-428 driver 3.09.
