- * usbusx2y.c - ALSA USB US-428 Driver
- *
- 2005-04-14 Karsten Wiese
- 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.
