|
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.
