| * usbusy2y.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. |
