| 5 | Version 0.8.7.2: |
| 6 | Call snd_card_free() instead of snd_card_free_in_thread() to prevent oops with dead keyboard symptom. |
| 7 | Tested ok with kernel 2.6.12-rc2. |
| 8 | |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 9 | 2004-12-14 Karsten Wiese |
| 10 | Version 0.8.7.1: |
| 11 | snd_pcm_open for rawusb pcm-devices now returns -EBUSY if called without rawusb's hwdep device being open. |
| 12 | |
| 13 | 2004-12-02 Karsten Wiese |
| 14 | Version 0.8.7: |
| 15 | Use macro usb_maxpacket() for portability. |
| 16 | |
| 17 | 2004-10-26 Karsten Wiese |
| 18 | Version 0.8.6: |
| 19 | wake_up() process waiting in usX2Y_urbs_start() on error. |
| 20 | |
| 21 | 2004-10-21 Karsten Wiese |
| 22 | Version 0.8.5: |
| 23 | nrpacks is runtime or compiletime configurable now with tested values from 1 to 4. |
| 24 | |
| 25 | 2004-10-03 Karsten Wiese |
| 26 | Version 0.8.2: |
| 27 | Avoid any possible racing while in prepare callback. |
| 28 | |
| 29 | 2004-09-30 Karsten Wiese |
| 30 | Version 0.8.0: |
| 31 | Simplified things and made ohci work again. |
| 32 | |
| 33 | 2004-09-20 Karsten Wiese |
| 34 | Version 0.7.3: |
| 35 | Use usb_kill_urb() instead of deprecated (kernel 2.6.9) usb_unlink_urb(). |
| 36 | |
| 37 | 2004-07-13 Karsten Wiese |
| 38 | Version 0.7.1: |
| 39 | Don't sleep in START/STOP callbacks anymore. |
| 40 | us428 channels C/D not handled just for this version, sorry. |
| 41 | |
| 42 | 2004-06-21 Karsten Wiese |
| 43 | Version 0.6.4: |
| 44 | Temporarely suspend midi input |
| 45 | to sanely call usb_set_interface() when setting format. |
| 46 | |
| 47 | 2004-06-12 Karsten Wiese |
| 48 | Version 0.6.3: |
| 49 | Made it thus the following rule is enforced: |
| 50 | "All pcm substreams of one usX2Y have to operate at the same rate & format." |
| 51 | |
| 52 | 2004-04-06 Karsten Wiese |
| 53 | Version 0.6.0: |
| 54 | Runs on 2.6.5 kernel without any "--with-debug=" things. |
| 55 | us224 reported running. |
| 56 | |
| 57 | 2004-01-14 Karsten Wiese |
| 58 | Version 0.5.1: |
| 59 | Runs with 2.6.1 kernel. |
| 60 | |
| 61 | 2003-12-30 Karsten Wiese |
| 62 | Version 0.4.1: |
| 63 | Fix 24Bit 4Channel capturing for the us428. |
| 64 | |
| 65 | 2003-11-27 Karsten Wiese, Martin Langer |
| 66 | Version 0.4: |
| 67 | us122 support. |
| 68 | us224 could be tested by uncommenting the sections containing USB_ID_US224 |
| 69 | |
| 70 | 2003-11-03 Karsten Wiese |
| 71 | Version 0.3: |
| 72 | 24Bit support. |
| 73 | "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. |
| 74 | |
| 75 | 2003-08-22 Karsten Wiese |
| 76 | Version 0.0.8: |
| 77 | Removed EZUSB Firmware. First Stage Firmwaredownload is now done by tascam-firmware downloader. |
| 78 | See: |
| 79 | http://usb-midi-fw.sourceforge.net/tascam-firmware.tar.gz |
| 80 | |
| 81 | 2003-06-18 Karsten Wiese |
| 82 | Version 0.0.5: |
| 83 | changed to compile with kernel 2.4.21 and alsa 0.9.4 |
| 84 | |
| 85 | 2002-10-16 Karsten Wiese |
| 86 | Version 0.0.4: |
| 87 | compiles again with alsa-current. |
| 88 | USB_ISO_ASAP not used anymore (most of the time), instead |
| 89 | urb->start_frame is calculated here now, some calls inside usb-driver don't need to happen anymore. |
| 90 | |
| 91 | To get the best out of this: |
| 92 | Disable APM-support in the kernel as APM-BIOS calls (once each second) hard disable interrupt for many precious milliseconds. |
| 93 | This helped me much on my slowish PII 400 & PIII 500. |
| 94 | ACPI yet untested but might cause the same bad behaviour. |
| 95 | Use a kernel with lowlatency and preemptiv patches applied. |
| 96 | To autoload snd-usb-midi append a line |
| 97 | post-install snd-usb-us428 modprobe snd-usb-midi |
| 98 | to /etc/modules.conf. |
| 99 | |
| 100 | known problems: |
| 101 | sliders, knobs, lights not yet handled except MASTER Volume slider. |
| 102 | "pcm -c 2" doesn't work. "pcm -c 2 -m direct_interleaved" does. |
| 103 | KDE3: "Enable full duplex operation" deadlocks. |
| 104 | |
| 105 | |
| 106 | 2002-08-31 Karsten Wiese |
| 107 | Version 0.0.3: audio also simplex; |
| 108 | simplifying: iso urbs only 1 packet, melted structs. |
| 109 | ASYNC_UNLINK not used anymore: no more crashes so far..... |
| 110 | for alsa 0.9 rc3. |
| 111 | |
| 112 | 2002-08-09 Karsten Wiese |
| 113 | Version 0.0.2: midi works with snd-usb-midi, audio (only fullduplex now) with i.e. bristol. |
| 114 | The firmware has been sniffed from win2k us-428 driver 3.09. |
